Fire extinguisher. 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. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i ...
Purple-K. Purple-K, also known as PKP, is a dry-chemical fire suppression agent used in some dry chemical fire extinguishers. [ 1] 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). [ 2]
Carbon tetrachloride fire extinguisher poster, USA, 1941–1944. A well-known brand of fire grenade was the "Red Comet", which was variously manufactured with other fire-fighting equipment in the Denver, Colorado area by the Red Comet Manufacturing Company from its founding in 1919 until manufacturing operations were closed in the early 1980s.
Fire hydrant in Charlottesville, Virginia, United States. A fire hydrant, fireplug, or firecock (archaic) [1] or "Johnny Pump" is a connection point by which firefighters can tap into a water supply. It is a component of active fire protection. Underground fire hydrants have been used in Europe and Asia since at least the 18th century.
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.
History. HMIS was introduced in 1981 as a resource for the paint and coatings industry, by the National Paint and Coatings Association, derived from systems developed by PPG Industries and DuPont. [3] Despite being a resource for the paint and coding industry, it soon expanded to general industries also looking to comply with OSHA regulations.
A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their combustion. [1] [2] Fire retardants may also cool the fuel through physical action or endothermic chemical reactions.
The flash point is a descriptive characteristic that is used to distinguish between flammable fuels, such as petrol (also known as gasoline ), and combustible fuels, such as diesel . It is also used to characterize the fire hazards of fuels. Fuels which have a flash point less than 37.8 °C (100.0 °F) are called flammable, whereas fuels having ...
