fire alarm is a unit made of several devices, which uses visual and audio signalization to warn people about a possible fire, smoke, or carbon monoxide occurrence in the area of coverage. Fire alarms are usually set in fire alarm systems to provide zonal coverage for residences and commercial buildings.
A fire proximity suit (also, silvers, silver bunker suit, or asbestos suit) is a suit designed to protect a firefighter or volcanologist from extremely high temperatures. They were first designed and used in the 1930s.
Chief fire officers and their deputies wear white helmets; regional and area commanders and their assistants wear silver helmets; and the national commander and their deputies wear black helmets. Trainee and recruit firefighters wear fluro-green helmets (previously red).
