MP-5 gas mask


The MP-5 gas mask is the standard gas mask of the Polish Armed Forces. This mask is designed to protect the user's respiratory tract from airborne toxic agents, radioactive dust and bacterial aerosols. For protection against toxic industrial agents such as ammonia or carbon monoxide, specific combined filters should be used additionally. The design also allows for the collection of fluids and conversation.
The masks are currently manufactured by Maskpol.

Development

In the mid-1980s, the Department of Respiratory Protection of the Military Institute of Chemistry and Radiometry in Warsaw began work on a new gas mask. It was to replace the previously introduced MP-4 masks. This study had the working name MP-5.
The first design had two screw-in absorbers. It also had a headgear from the MP-4 mask and polycarbonate goggles. However, one absorber located centrally was ultimately used.
