Construction and renovation fires
Construction and renovation are common circumstances for fires, which present particular difficulties to firefighters.
During construction, buildings often do not have elements that would protect them from fire, such as walls and sprinkler systems. Poor water supplies and the accumulation of flammable materials also present risks. Works often require heat or even open flame, and these can set off fires that smoulder for hours before being noticed. For this reason, work sites may need 24-hour fire watches.
Builder's risk insurance may cover damage from such fires.
