Fire protection equipment extinguishes fires, prevents flames from spreading, and alerts building occupants to potential hazards. They also help facilities comply with fire regulations as determined by local fire marshals. Carbon monoxide and smoke detectors alert occupants to toxic gases and smoke so they can evacuate the area. Fire extinguishers combat small fires until firefighting teams respond. Fire hoses and fire hydrant and standpipe accessories ensure firefighters can move water from the water source to the fire. Firestops, barriers, and flame-resistant treatments help prevent flames from starting or spreading.
