A stored-pressure fire extinguisher made by Amerex. 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.
An ABC dry chemical fire extinguisher made by Amerex. Monoammonium phosphate, ABC Dry Chemical, ABC Powder, tri-class, or multi-purpose dry chemical is a dry chemical extinguishing agent used on class A, class B, and class C fires. It uses a specially fluidized and siliconized monoammonium phosphate powder. [1]
Examples of automatic systems include fire sprinkler system, gaseous fire suppression, and condensed aerosol fire suppression. When fires are extinguished in the early stages loss of life is minimal since 93% of all fire-related deaths occur once the fire has progressed beyond the early stages.
A historical device used to squirt water onto a fire by hand. Also called simply a squirt or a syringe, these are perhaps the simplest and most ancient form of fire extinguisher. Known from the times of the Roman Empire but not documented in Europe until the 16th century.
Commonly referred to as "Fast Flow" or "High Performance" extinguishers. Available in 6 kg (13 lb), 9 kg (20 lb), and 14 kg (30 lb). capacities and contain ABC Dry Chemical, Purple-K, or sodium bicarbonate.
This was a common problem when carbon tetrachloride was used as a fire extinguisher: there have been deaths due to its conversion to phosgene reported. Carbon tetrachloride is a suspected human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
Purple-K, also known as PKP, is a dry-chemical fire suppression agent used in some dry chemical fire extinguishers. It is the second most effective dry chemical in fighting class B (flammable liquid) fires after Monnex (potassium allophanate), and can be used against some energized electrical equipment fires (USA class C fires).

The use of a cutting extinguisher is a fire extinguishing technique that combines abrasive waterjet cutting with water spray extinguishing, through a single handpiece or nozzle. The fire-fighter approaches the fire from outside the main fire area, then uses the cutting action to drill a small hole through a door or wall.
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.
1,1,1,2,3,3,3-Heptafluoropropane, also called heptafluoropropane, HFC-227ea ( ISO name), HFC-227 or FM-200, as well as apaflurane ( INN ), is a colourless, odourless gaseous halocarbon commonly used as a gaseous fire suppression agent.
