It is generally used in situations where water from a fire sprinkler would damage expensive equipment, or where water-based fire protection is impractical, such as museums, banks, clean rooms and hospitals. The HFC-125 clean agent is stored in a pressurized container and introduced into the hazard as a gas.
Condensed aerosol fire suppression systems employ a fire-extinguishing agent consisting of very finely divided solid particles, suspended in an inert gas. Those superfine aerosol particles are pyrotechnically generated via the combustion of an aerosol-forming agent (AFA) which is stable at room temperature and does not need to be stored in a ...
Gaseous fire suppression, also called clean agent fire suppression, is the use of inert gases and chemical agents to extinguish a fire. These agents are governed by the National Fire Protection Association (NFPA) Standard for Clean Agent Fire Extinguishing Systems – NFPA 2001 in the US, with different standards and regulations elsewhere.
Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.
Halon systems are among the most effective and commonly used fire protection systems used on commercial aircraft. Halon 1301 is the primary agent used in commercial aviation engine, cargo compartments, and auxiliary power unit fire zones. [9] [10] Efforts to find a suitable replacement for Halon 1301 have not produced a widely accepted replacement.
A stored-pressure fire extinguisher. A fire extinguisher is a handheld active fire protection device usually filled with a dry or wet chemical used to extinguish or control small fires, often in emergencies.
Fire extinguishers are one of the most common manual fire suppression devices and are required in all commercial buildings and vehicles. [2] Fire extinguishers can be used with little to no training and are meant for small incipient stage fires. The most common extinguisher is the ABC extinguisher and are found in most offices and homes.
An Ansul fire suppression system in a hospital cafeteria Fire suppression systems are used to extinguish, control, or in some cases, entirely prevent fires from spreading or occurring. Fire suppression systems have an incredibly large variety of applications, and as such, there are many different types of suppression systems for different ...
