Occupational safety and health
Occupational safety and health, also commonly referred to as health and safety, occupational health and safety, occupational health, or occupational safety, is a multidisciplinary field concerned with the safety, health, and welfare of people at work. These terms also refer to the goals of this field, so their use in the sense of this article was originally an abbreviation of occupational safety and health program/department etc.
The goal of an occupational safety and health program is to foster a safe and healthy work environment. OSH may also protect co-workers, family members, employers, customers, and many others who might be affected by the workplace environment.
In common-law jurisdictions, employers have a common law duty to take reasonable care of the safety of their employees. Statute law may, in addition, impose other general duties, introduce specific duties, and create government bodies with powers to regulate workplace safety issues: details of this vary from jurisdiction to jurisdiction.
DefinitionAs defined by the World Health Organization "occupational health deals with all aspects of health and safety in the workplace and has a strong focus on primary prevention of hazards." Health has been defined as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." Occupational health is a multidisciplinary field of healthcare concerned with enabling an individual to undertake their occupation, in the way that causes least harm to their health. It contrasts, for example, with the promotion of health and safety at work, which is concerned with preventing harm from any incidental hazards, arising in the workplace.
Since 1950, the International Labour Organization and the World Health Organization have shared a common definition of occupational health. It was adopted by the Joint ILO/WHO Committee on Occupational Health at its first session in 1950 and revised at its twelfth session in 1995. The definition reads:
Those in the field of occupational health come from a wide range of disciplines and professions including medicine, psychology, epidemiology, physiotherapy and rehabilitation, occupational therapy, occupational medicine, human factors and ergonomics, and many others. Professionals advise on a broad range of occupational health matters. These include how to avoid particular pre-existing conditions causing a problem in the occupation, correct posture for the work, frequency of rest breaks, preventive action that can be undertaken, and so forth.
"Occupational health should aim at: the promotion and maintenance of the highest degree of physical, mental and social well-being of workers in all occupations; the prevention amongst workers of departures from health caused by their working conditions; the protection of workers in their employment from risks resulting from factors adverse to health; the placing and maintenance of the worker in an occupational environment adapted to his physiological and psychological capabilities; and, to summarize, the adaptation of work to man and of each man to his job.
HistoryThe research and regulation of occupational safety and health are a relatively recent phenomenon. As labor movements arose in response to worker concerns in the wake of the industrial revolution, worker's health entered consideration as a labor-related issue.
In the United Kingdom, the Factory Acts of the early nineteenth century arose out of concerns about the poor health of children working in cotton mills: the Act of 1833 created a dedicated professional Factory Inspectorate. The initial remit of the Inspectorate was to police restrictions on the working hours in the textile industry of children and young persons. However, on the urging of the Factory Inspectorate, a further Act in 1844 giving similar restrictions on working hours for women in the textile industry introduced a requirement for machinery guarding.
In 1840 a Royal Commission published its findings on the state of conditions for the workers of the mining industry that documented the appallingly dangerous environment that they had to work in and the high frequency of accidents. The commission sparked public outrage which resulted in the Mines Act of 1842. The act set up an inspectorate for mines and collieries which resulted in many prosecutions and safety improvements, and by 1850, inspectors were able to enter and inspect premises at their discretion.
Otto von Bismarck inaugurated the first social insurance legislation in 1883 and the first worker's compensation law in 1884 – the first of their kind in the Western world. Similar acts followed in other countries, partly in response to labor unrest.
Workplace hazardsAlthough work provides many economic and other benefits, a wide array of workplace hazards also present risks to the health and safety of people at work. These include but are not limited to, "chemicals, biological agents, physical factors, adverse ergonomic conditions, allergens, a complex network of safety risks," and a broad range of psychosocial risk factors. Personal protective equipment can help protect against many of these hazards.
Physical hazards affect many people in the workplace. Occupational hearing loss is the most common work-related injury in the United States, with 22 million workers exposed to hazardous noise levels at work and an estimated $242 million spent annually on worker's compensation for hearing loss disability. Falls are also a common cause of occupational injuries and fatalities, especially in construction, extraction, transportation, healthcare, and building cleaning and maintenance. Machines have moving parts, sharp edges, hot surfaces and other hazards with the potential to crush, burn, cut, shear, stab or otherwise strike or wound workers if used unsafely.
Biological hazards include infectious microorganisms such as viruses and toxins produced by those organisms such as anthrax. Biohazards affect workers in many industries; influenza, for example, affects a broad population of workers. Outdoor workers, including farmers, landscapers, and construction workers, risk exposure to numerous biohazards, including animal bites and stings, urushiol from poisonous plants, and diseases transmitted through animals such as the West Nile virus and Lyme disease. Health care workers, including veterinary health workers, risk exposure to blood-borne pathogens and various infectious diseases, especially those that are emerging.
Dangerous chemicals can pose a chemical hazard in the workplace. There are many classifications of hazardous chemicals, including neurotoxins, immune agents, dermatologic agents, carcinogens, reproductive toxins, systemic toxins, asthmagens, pneumoconiotic agents, and sensitizers. Authorities such as regulatory agencies set occupational exposure limits to mitigate the risk of chemical hazards. An international effort is investigating the health effects of mixtures of chemicals. There is some evidence that certain chemicals are harmful at lower levels when mixed with one or more other chemicals. This may be particularly important in causing cancer.
Psychosocial hazards include risks to the mental and emotional well-being of workers, such as feelings of job insecurity, long work hours, and poor work-life balance. A recent Cochrane review - using moderate quality evidence - related that the addition of work-directed interventions for depressed workers receiving clinical interventions reduces the number of lost work days as compared to clinical interventions alone. This review also demonstrated that the addition of cognitive behavioral therapy to primary or occupational care and the addition of a "structured telephone outreach and care management program" to usual care are both effective at reducing sick leave days.
By industrySpecific occupational safety and health risk factors vary depending on the specific sector and industry. Construction workers might be particularly at risk of falls, for instance, whereas fishermen might be particularly at risk of drowning. The United States Bureau of Labor Statistics identifies the fishing, aviation, lumber, metalworking, agriculture, mining and transportation industries as among some of the more dangerous for workers. Similarly psychosocial risks such as workplace violence are more pronounced for certain occupational groups such as health care employees, police, correctional officers and teachers.
ConstructionConstruction is one of the most dangerous occupations in the world, incurring more occupational fatalities than any other sector in both the United States and in the European Union. In 2009, the fatal occupational injury rate among construction workers in the United States was nearly three times that for all workers. Falls are one of the most common causes of fatal and non-fatal injuries among construction workers. Proper safety equipment such as harnesses and guardrails and procedures such as securing ladders and inspecting scaffolding can curtail the risk of occupational injuries in the construction industry. Due to the fact that accidents may have disastrous consequences for employees as well as organizations, it is of utmost importance to ensure health and safety of workers and compliance with HSE construction requirements. Health and safety legislation in the construction industry involves many rules and regulations. For example, the role of the Construction Design Management Coordinator as a requirement has been aimed at improving health and safety on-site.
The 2010 National Health Interview Survey Occupational Health Supplement identified work organization factors and occupational psychosocial and chemical/physical exposures which may increase some health risks. Among all U.S. workers in the construction sector, 44% had non-standard work arrangements compared to 19% of all U.S. workers, 15% had temporary employment compared to 7% of all U.S. workers, and 55% experienced job insecurity compared to 32% of all U.S. workers. Prevalence rates for exposure to physical/chemical hazards were especially high for the construction sector. Among nonsmoking workers, 24% of construction workers were exposed to secondhand smoke while only 10% of all U.S. workers were exposed. Other physical/chemical hazards with high prevalence rates in the construction industry were frequently working outdoors and frequent exposure to vapors, gas, dust, or fumes.
AgricultureAgriculture workers are often at risk of work-related injuries, lung disease, noise-induced hearing loss, skin disease, as well as certain cancers related to chemical use or prolonged sun exposure. On industrialized farms, injuries frequently involve the use of agricultural machinery. The most common cause of fatal agricultural injuries in the United States is tractor rollovers, which can be prevented by the use of roll over protection structures which limit the risk of injury in case a tractor rolls over. Pesticides and other chemicals used in farming can also be hazardous to worker health, and workers exposed to pesticides may experience illnesses or birth defects. As an industry in which families, including children, commonly work alongside their families, agriculture is a common source of occupational injuries and illnesses among younger workers. Common causes of fatal injuries among young farm worker include drowning, machinery and motor vehicle-related accidents.
The 2010 NHIS-OHS found elevated prevalence rates of several occupational exposures in the agriculture, forestry, and fishing sector which may negatively impact health. These workers often worked long hours. The prevalence rate of working more than 48 hours a week among workers employed in these industries was 37%, and 24% worked more than 60 hours a week. Of all workers in these industries, 85% frequently worked outdoors compared to 25% of all U.S. workers. Additionally, 53% were frequently exposed to vapors, gas, dust, or fumes, compared to 25% of all U.S. workers.
Service sectorAs the number of service sector jobs has risen in developed countries, more and more jobs have become sedentary, presenting a different array of health problems than those associated with manufacturing and the primary sector. Contemporary problems such as the growing rate of obesity and issues relating to occupational stress, workplace bullying, and overwork in many countries have further complicated the interaction between work and health.
According to data from the 2010 NHIS-OHS, hazardous physical/chemical exposures in the service sector were lower than national averages. On the other hand, potentially harmful work organization characteristics and psychosocial workplace exposures were relatively common in this sector. Among all workers in the service industry, 30% experienced job insecurity in 2010, 27% worked non-standard shifts, 21% had non-standard work arrangements.
Due to the manual labour involved and on a per employee basis, the US Postal Service, UPS and FedEx are the 4th, 5th and 7th most dangerous companies to work for in the US.
Mining and oil and gas extractionThe mining industry still has one of the highest rates of fatalities of any industry. There are a range of hazards present in surface and underground mining operations. In surface mining, leading hazards include such issues as geological stability, contact with plant and equipment, blasting, thermal environments, respiratory health In underground mining operations hazards include respiratory health, explosions and gas, geological instability, electrical equipment, contact with plant and equipment, heat stress, inrush of bodies of water, falls from height, confined spaces. ionising radiation
According to data from the 2010 NHIS-OHS, workers employed in mining and oil and gas extraction industries had high prevalence rates of exposure to potentially harmful work organization characteristics and hazardous chemicals. Many of these workers worked long hours: 50% worked more than 48 hours a week and 25% worked more than 60 hours a week in 2010. Additionally, 42% worked non-standard shifts. These workers also had high prevalence of exposure to physical/chemical hazards. In 2010, 39% had frequent skin contact with chemicals. Among nonsmoking workers, 28% of those in mining and oil and gas extraction industries had frequent exposure to secondhand smoke at work. About two-thirds were frequently exposed to vapors, gas, dust, or fumes at work.
Healthcare and social assistanceHealthcare workers are exposed to many hazards that can adversely affect their health and well-being. Long hours, changing shifts, physically demanding tasks, violence, and exposures to infectious diseases and harmful chemicals are examples of hazards that put these workers at risk for illness and injury.
According to the Bureau of Labor statistics, U.S. hospitals recorded 253,700 work-related injuries and illnesses in 2011, which is 6.8 work-related injuries and illnesses for every 100 full-time employees. The injury and illness rate in hospitals is higher than the rates in construction and manufacturing – two industries that are traditionally thought to be relatively hazardous.
Workplace fatality and injury statistics
United StatesThe Occupational Safety and Health Statistics program in the Bureau of Labor Statistics of the United States Department of Labor compiles information about workplace fatalities and non-fatal injuries in the United States. The OSHS program produces three annual reports:
- Counts and rates of nonfatal occupational injuries and illnesses by detailed industry and case type
- Case circumstances and worker demographic data for nonfatal occupational injuries and illnesses resulting in days away from work
- Counts and rates of fatal occupational injuries
The Bureau also compiles information about the most dangerous jobs. According to the census of occupational injuries 4,679 people died on the job in 2014. In 2015, a decline in nonfatal workplace injuries and illnesses was observed, with private industry employers reporting approximately 2.9 million incidents, nearly 48,000 fewer cases than in 2014. The Bureau also uses tools like www.AgInjuryNews.org to identify and compile additional sources of fatality reports for their datasets.
A total of 5,147 workers died from a work-related injury in the U.S. in 2017, down slightly from the 2016 total of 5,190. The fatal injury rate was 3.5 per 100,000 full-time equivalent workers, also down from 3.6 in 2016.
About 2.8 million nonfatal workplace injuries and illnesses were reported by private industry employers in 2017, occurring at a rate of 2.8 cases per 100 full-time workers. Both the number of injuries and illnesses and the rate of these cases declined from 2016.
European UnionIn most countries males comprise the vast majority of workplace fatalities. In the EU as a whole, 94% of death were of males. In the UK the disparity was even greater with males comprising 97.4% of workplace deaths. In the UK there were 171 fatal injuries at work in financial year 2011–2012, compared with 651 in calendar year 1974; the fatal injury rate declined over that period from 2.9 fatalities per 100,000 workers to 0.6 per 100,000 workers. Of course the period saw the virtual disappearance from the UK of some historically risky industries.
Russian FederationOne of the decisions taken by Communists during the reign of Stalin was the reduction in the number of accidents and occupational diseases to zero. The tendency to decline remained in the RF in the early 21st century, and the same methods of falsification are used, so that the real occupational morbidity and the number of accidents are unknown.
After the destruction of the USSR, the enterprises became owned by new owners who were not interested in preserving the life and health of workers. They did not spend money on equipment modernization, and the share of harmful workplaces increased. The state did not interfere in this, and sometimes it helped employers. At first, the process of growth was slow - due to the fact that in the 1990s this was compensated by mass de-industrialization. In the 2000s, this method of restraining the growth of the share of harmful workplaces was exhausted. Therefore, in the 2010s the Ministry of Labor adopted the Federal law 426-FZ, which equated the issuance of personal protective equipment to the employee to real improvement of working conditions; and the Ministry of Health made significant changes in the methods of risk assessment in the workplace. This explains the "decline" in the proportion of workers working in harmful conditions after 2014 - it happened not in practice, but only on paper.
Specialists from the Izmerov Research Institute of Occupational Health analyzed information about the health status of workers and the assessment of their working conditions using the new methods of risk assessment. Their findings show that new "methods" do not provide a real picture of working conditions. This is most clearly shown by the results obtained at enterprises producing aluminum. For example, the share of jobs with very harmful working conditions decreased by an order of magnitude. But the reduction of the level of harmful factors at these enterprises did not happen at all; and the proportion of workers suffering from chronic intoxication with fluorine compounds was 38.7%.
In the opinion of the state inspector, the use of punishment against the guilty manager is too rare: "The practice of court decisions shows that disqualification of the leader is possible, but for this he or she must kill 5-7 employees, or more". Responsibility for wrong decisions is absent or very low; and punishment of guilty executives in the construction industry usually does not occur.
NationalNational management system standards for occupational health and safety include AS/NZS 4801-2001 for Australia and New Zealand, CAN/CSA-Z1000-14 for Canada and ANSI/ASSE Z10-2012 for the United States. Association Française de Normalisation in France also developed occupational safety and health management standards. In the United Kingdom, non-departmental public body Health and Safety Executive published Managing for health and safety, an online guidance. In Germany, the state factory inspectorates of Bavaria and Saxony had introduced the management system OHRIS. In the Netherlands, the management system Safety Certificate Contractors combines management of occupational health and safety and the environment.
Internationalwas published in March 2018.
Previously, the International Labour Organization published ILO-OSH 2001, also titled "Guidelines on occupational safety and health management systems" to assist organizations with introducing OSH management systems. These guidelines encourage continual improvement in employee health and safety, achieved via a constant process of policy, organization, planning & implementation, evaluation, and action for improvement, all supported by constant auditing to determine the success of OSH actions. From 1999 to 2018, the occupational health and safety management system standard OHSAS 18001 was adopted as a British and Polish standard and widely used internationally. OHSAS 18000 comprised two parts, OHSAS 18001 and 18002 and was developed by a selection of leading trade bodies, international standards and certification bodies to address a gap where no third-party certifiable international standard existed. It was intended to integrate with ISO 9001 and ISO 14001.
National legislation and public organizationsOccupational safety and health practice vary among nations with different approaches to legislation, regulation, enforcement, and incentives for compliance. In the EU, for example, some member states promote OSH by providing public monies as subsidies, grants or financing, while others have created tax system incentives for OSH investments. A third group of EU member states has experimented with using workplace accident insurance premium discounts for companies or organisations with strong OSH records.territories have enacted and administer harmonised Work Health and Safety Legislation in accordance with the Intergovernmental Agreement for Regulatory and Operational Reform in Occupational Health and Safety. Each of these jurisdictions has enacted Work Health & Safety legislation and regulations based on the Commonwealth Work Health and Safety Act 2011 and common Codes of Practice developed by Safe Work Australia. Some jurisdictions have also included mine safety under the model approach, however, most have retained separate legislation for the time being. In August 2019 Western Australia committed to join nearly every other State and Territory in implementing the harmonised Model WHS Act, Regulations and other subsidiary legislation. Victoria has retained its own regime, although the Model WHS laws themselves drew heavily on the Victoria approach.
CanadaIn Canada, workers are covered by provincial or federal labour codes depending on the sector in which they work. Workers covered by federal legislation are covered by the Canada Labour Code; all other workers are covered by the health and safety legislation of the province in which they work. The Canadian Centre for Occupational Health and Safety, an agency of the Government of Canada, was created in 1966 by an Act of Parliament. The act was based on the belief that all Canadians had "...a fundamental right to a healthy and safe working environment." CCOHS is mandated to promote safe and healthy workplaces to help prevent work-related injuries and illnesses. The CCOHS maintains a useful list of OSH regulations for Canada and its provinces.
European UnionIn the European Union, member states have enforcing authorities to ensure that the basic legal requirements relating to occupational health and safety are met. In many EU countries, there is strong cooperation between employer and worker organisations to ensure good OSH performance as it is recognized this has benefits for both the worker and the enterprise. In 1996, the European Agency for Safety and Health at Work was founded.
Member states of the European Union have all transposed into their national legislation a series of directives that establish minimum standards on occupational health and safety. These directives follow a similar structure requiring the employer to assess the workplace risks and put in place preventive measures based on a hierarchy of control. This hierarchy starts with elimination of the hazard and ends with personal protective equipment.
However, certain EU member states admit to having lacking quality control in occupational safety services, to situations in which risk analysis takes place without any on-site workplace visits and to insufficient implementation of certain EU OSH directives. Based on this, it is hardly surprising that the total societal costs of work-related health problems and accidents vary from 2.6% to 3.8% of GNP between the EU member states.
IrelandThe main health and safety law in Ireland is the Safety, Health and Welfare at Work Act 2005, which replaced earlier 1989 legislation. The Health and Safety Authority, based in Dublin, is responsible for enforcing health and safety at work legislation.Ministry of Labour is the authority responsible for issues relating to labour environment. The National Institute for Labour Safety and Hygiene is the technical public Organization specialized in occupational safety and health.Swedish Work Environment Authority is the government agency responsible for issues relating to the working environment. The agency should work to disseminate information and furnish advice on OSH, has a mandate to carry out inspections, and a right to issue stipulations and injunctions to any non-compliant employer.Ministry of Manpower is responsible to ensure the safety, health and welfare of workers while working, in a factory, or even the area surrounding the factory where labourers work. There are a few rules that control the safety of workers, for example Occupational Safety Act 1970 or Occupational Health Act 1992. The sanctions, however, are still low and the violations of these laws are still at a high rate - with a maximum of 15 million rupiahs fine and/or a maximum of 1 year in prison.Occupational Safety and Health Act 1994. Malaysia has a statutory mechanism for worker involvement through elected health and safety representatives and health and safety committees. This followed a similar approach originally adopted in Scandinavia.the People's Republic of China, the Ministry of Health is responsible for occupational disease prevention and the State Administration of Work Safety for safety issues at work. On the provincial and municipal level, there are Health Supervisions for occupational health and local bureaus of Work Safety for safety. The "Occupational Disease Control Act of PRC" came into force on May 1, 2002. and Work safety Act of PRC on November 1, 2002. The Occupational Disease Control Act is under revision. The prevention of occupational disease is still in its initial stage compared with industrialised countries such as the US or UK.Department of Employment and Labour is responsible for occupational health and safety inspection and enforcement in commerce and industry apart from mining and energy production, where the Department of Mineral Resources is responsible.
The main statutory legislation on Health and Safety in the jurisdiction of the Department of Labour is Act No. 85 of 1993: Occupational Health and Safety Act as amended by Occupational Health and Safety Amendment Act, No. 181 Of 1993.
Regulations to the OHS Act include:
- General Administrative Regulations, 2003
- Certificate of Competency Regulations, 1990
- Construction Regulations, 2014
- Diving Regulations 2009
- Driven Machinery Regulations, 1988
- Environmental Regulations for Workplaces, 1987
- General Machinery regulations, 1988
- General Safety Regulations, 1986
- Noise induced hearing loss regulations, 2003
- Pressure Equipment Regulations, 2004
In 2007, the Taiwan Occupational Safety and Health Management System, which defined the basic regulations about occupational safety standard, was released.
United Arab Emirateswas introduced in February 2010 to regulate the implementation of occupational health and safety in the emirates of Abu Dhabi.
United KingdomHealth and safety legislation in the UK is drawn up and enforced by the Health and Safety Executive and local authorities under the Health and Safety at Work etc. Act 1974. HASAWA introduced a general duty on an employer to ensure, so far as is reasonably practicable, the health, safety and welfare at work of all his employees; with the intention of giving a legal framework supporting 'codes of practice' not in themselves having legal force but establishing a strong presumption as to what was reasonably practicable. The previous reliance on detailed prescriptive rule-setting was seen as having failed to respond rapidly enough to technological change, leaving new technologies potentially un-regulated or inappropriately regulated. HSE has continued to make some regulations giving absolute duties but in the UK the regulatory trend is away from prescriptive rules, and towards 'goal setting' and risk assessment. Recent major changes to the laws governing asbestos and fire safety management embrace the concept of risk assessment. The other key aspect of the UK legislation is a statutory mechanism for worker involvement through elected health and safety representatives and health and safety committees. This followed a similar approach in Scandinavia, and that approach has since been adopted in countries such as Australia, Canada, New Zealand and Malaysia.
For the UK, the government organisation dealing with occupational health has been the Employment Medical Advisory Service but in 2014 a new occupational health organisation - the Health and Work Service - was created to provide advice and assistance to employers in order to get back to work employees on long-term sick-leave. The service, funded by government, will offer medical assessments and treatment plans, on a voluntary basis, to people on long-term absence from their employer; in return, the government will no longer foot the bill for Statutory Sick Pay provided by the employer to the individual.
The UK has now left the European Union. A transition period is in place while the EU and UK negotiate new arrangements for a trade deal, which will end on 31 December 2020. An employer's responsibility to protect the health and safety of people affected by their work activities remains unchanged during the transition period.
United StatesIn the United States, President Richard Nixon signed the Occupational Safety and Health Act into law on December 29, 1970. The act created the three agencies which administer OSH, the Occupational Safety and Health Administration, National Institute for Occupational Safety and Health, and the Occupational Safety and Health Review Commission. The act authorized the Occupational Safety and Health Administration to regulate private employers in the 50 states, the District of Columbia, and territories. The Act establishing it includes a general duty clause requiring an employer to comply with the Act and regulations derived from it, and to provide employees with "employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm".
OSHA was established in 1971 under the Department of Labor. It has headquarters in Washington, DC and ten regional offices, further broken down into districts, each organized into three sections; compliance, training, and assistance. Its stated mission is to assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance. The original plan was for OSHA to oversee 50 state plans with OSHA funding 50% of each plan, although it has not worked out that way: there are currently 26 approved state plans, and no other states want to participate. OSHA manages the plan in the states not participating.
OSHA develops safety standards in the Code of Federal Regulations and enforces those safety standards through compliance inspections conducted by Compliance Officers; enforcement resources are focussed on high-hazard industries. Worksites may apply to enter OSHA's Voluntary Protection Program ; a successful application leads to an on-site inspection; if this is passed the site gains VPP status and OSHA no longer inspect it annually nor visit it unless there is a fatal accident or an employee complaint until VPP revalidation. VPP sites generally have injury and illness rates less than half the average for their industry.
It has 73 specialists in local offices to provide tailored information and training to employers and employees at little or no cost. Similarly OSHA produces a range of publications, provides advice to employers and funds consultation services available for small businesses.
OSHA's Alliance Program enables groups committed to worker safety and health to work with it to develop compliance assistance tools and resources, share information with workers and employers, and educate them about their rights and responsibilities. OSHA also has a Strategic Partnership Program that zeros in on specific hazards or specific geographic areas. OSHA manages Susan B. Harwood grants to non-profit organisations to train workers and employers to recognize, avoid, and prevent safety and health hazards in the workplace. Grants focus on small business, hard-to-reach workers and high-hazard industries.
The National Institute for Occupational Safety and Health, created under the same act, works closely with OSHA and provides the research behind many of OSHA's regulations and standards.
Professional roles and responsibilitiesThe roles and responsibilities of OSH professionals vary regionally, but may include evaluating working environments, developing, endorsing and encouraging measures that might prevent injuries and illnesses, providing OSH information to employers, employees, and the public, providing medical examinations, and assessing the success of worker health programs.

Differences between countries and regions
Identifying safety and health hazards
Hazards, risks, outcomesThe terminology used in OSH varies between countries, but generally speaking:
- A hazard is something that can cause harm if not controlled.
- The outcome is the harm that results from an uncontrolled hazard.
- A risk is a combination of the probability that a particular outcome will occur and the severity of the harm involved.
Hazard identificationHazard identification or assessment is an important step in the overall risk assessment and risk management process. It is where individual work hazards are identified, assessed and controlled/eliminated as close to source as reasonably as possible. As technology, resources, social expectation or regulatory requirements change, hazard analysis focuses controls more closely toward the source of the hazard. Thus hazard control is a dynamic program of prevention. Hazard based programs also have the advantage of not assigning or implying there are "acceptable risks" in the workplace. A hazard-based program may not be able to eliminate all risks, but neither does it accept "satisfactory" – but still risky – outcomes. And as those who calculate and manage the risk are usually managers while those exposed to the risks are a different group, workers, a hazard-based approach can by-pass conflict inherent in a risk-based approach.
The information that needs to be gathered from sources should apply to the specific type of work from which the hazards can come from. As mentioned previously, examples of these sources include interviews with people who have worked in the field of the hazard, history and analysis of past incidents, and official reports of work and the hazards encountered. Of these, the personnel interviews may be the most critical in identifying undocumented practices, events, releases, hazards and other relevant information. Once the information is gathered from a collection of sources, it is recommended for these to be digitally archived and to have a physical set of the same information in order for it to be more accessible. One innovative way to display the complex historical hazard information is with a historical hazards identification map, which distills the hazard information into an easy to use graphical format.
Risk assessmentModern occupational safety and health legislation usually demands that a risk assessment be carried out prior to making an intervention. It should be kept in mind that risk management requires risk to be managed to a level which is as low as is reasonably practical.
This assessment should:
- Identify the hazards
- Identify all affected by the hazard and how
- Evaluate the risk
- Identify and prioritize appropriate control measures.
The assessment should be recorded and reviewed periodically and whenever there is a significant change to work practices. The assessment should include practical recommendations to control the risk. Once recommended controls are implemented, the risk should be re-calculated to determine if it has been lowered to an acceptable level. Generally speaking, newly introduced controls should lower risk by one level, i.e., from high to medium or from medium to low.
Contemporary developmentsOn an international scale, the World Health Organization and the International Labour Organization have begun focusing on labour environments in developing nations with projects such as Healthy Cities. Many of these developing countries are stuck in a situation in which their relative lack of resources to invest in OSH leads to increased costs due to work-related illnesses and accidents. The European Agency for Safety and Health at Work states indicates that nations having less developed OSH systems spend a higher fraction of their gross national product on job-related injuries and illness – taking resources away from more productive activities. The ILO estimates that work-related illness and accidents cost up to 10% of GDP in Latin America, compared with just 2.6% to 3.8% in the EU." There is continued use of asbestos, a notorious hazard, in some developing countries. So asbestos-related disease is, sadly, expected to continue to be a significant problem well into the future.
Augmented Reality, Virtual Reality and Artificial IntelligenceThe impact of technologies on health and safety is an emerging field of research and practice. The opportunities for improving health and safety through use of augmented reality are now endless. There are emerging technologies for which the range of health and safety implications are not well understood and the impacts of machine learning and its impact on worker health and safety and the health and safety profession is still emerging. New technologies and ways of working introduce new risks and challenges for WHS and workers’ compensation, but they also have the potential to make work safer and reduce workplace injury.
Nanotechnologyis an example of a new, relatively unstudied technology. A Swiss survey of one hundred thirty eight companies using or producing nanoparticulate matter in 2006 resulted in forty completed questionnaires. Sixty five per cent of respondent companies stated they did not have a formal risk assessment process for dealing with nanoparticulate matter. Nanotechnology already presents new issues for OSH professionals that will only become more difficult as nanostructures become more complex. The size of the particles renders most containment and personal protective equipment ineffective. The toxicology values for macro sized industrial substances are rendered inaccurate due to the unique nature of nanoparticulate matter. As nanoparticulate matter decreases in size its relative surface area increases dramatically, increasing any catalytic effect or chemical reactivity substantially versus the known value for the macro substance. This presents a new set of challenges in the near future to rethink contemporary measures to safeguard the health and welfare of employees against a nanoparticulate substance that most conventional controls have not been designed to manage.
CoronavirusMany countries' health and safety at work arrangements are currently focused on protection against the spread of COVID-19. Both broad and industry-specific workplace hazard controls for COVID-19 have been proposed to minimize risks of disease transmission in the workplace.
The National Institute of Occupational Safety and Health National Occupational Research Agenda established an externally-lead Covid-19 workgroup to provide exposure control information specific to working in manufacturing environments. The workgroup identified disseminating information most relevant to manufacturing workplaces as a priority, and that would include providing content in Wikipedia. This includes evidence-based practices for infection control plans, and communication tools.
Occupational health disparitiesOccupational health disparities refer to differences in occupational injuries and illnesses that are closely linked with demographic, social, cultural, economic, and/or political factors.
EducationThere are multiple levels of training applicable to the field of occupational safety and health. Programs range from individual non-credit certificates, focusing on specific areas of concern, to full doctoral programs. The University of Southern California was one of the first schools in the US to offer a Ph.D. program focusing on the field. Further, multiple master's degree programs exist, such as that of the Indiana State University who offer a master of science and a master of arts in OSH. Graduate programs are designed to train educators, as well as, high-level practitioners. Many OSH generalists focus on undergraduate studies; programs within schools, such as that of the University of North Carolina's online Bachelor of Science in Environmental Health and Safety, fill a large majority of hygienist needs. However, smaller companies often do not have full-time safety specialists on staff, thus, they appoint a current employee to the responsibility. Individuals finding themselves in positions such as these, or for those enhancing marketability in the job-search and promotion arena, may seek out a credit certificate program. For example, the University of Connecticut's online OSH Certificate, provides students familiarity with overarching concepts through a 15-credit program. Programs such as these are often adequate tools in building a strong educational platform for new safety managers with a minimal outlay of time and money. Further, most hygienists seek certification by organizations that train in specific areas of concentration, focusing on isolated workplace hazards. The American Society for Safety Engineers, American Board of Industrial Hygiene, and American Industrial Hygiene Association offer individual certificates on many different subjects from forklift operation to waste disposal and are the chief facilitators of continuing education in the OSH sector. In the U.S. the training of safety professionals is supported by National Institute for Occupational Safety and Health through their NIOSH Education and Research Centers.
In Australia, training in OSH is available at the vocational education and training level, and at university undergraduate and postgraduate level. Such university courses may be accredited by an Accreditation Board of the Safety Institute of Australia. The Institute has produced a Body of Knowledge which it considers is required by a generalist safety and health professional, and offers a professional qualification based on a four-step assessment.
One form of training delivered in the workplace is known as a "toolbox talk". According to the UK's Health and Safety Executive, a toolbox talk is a short presentation to the workforce on a single aspect of health and safety. Such talks are often used, especially in the construction industry, by site supervisors, front line managers and owners of small construction firms to prepare and deliver advice on matters of health, safety and the environment and to obtain feedback from the workforce.
