In the United States they can last for several years, but must be inspected annually.
A portable fire extinguisher will take between 10 and 60 seconds to be empty, unless it is larger than 40 pounds. A fixed fire extinguisher may last between 40 seconds and four minutes (the latter to fill an airplane hangar with high-expansion foam).
A fire extinguisher is a fire protection device used to put out or control small fires, usually in emergency situations. A typical self-expelling fire extinguisher empties its contents in under a minute.
Well if your using a big water/foam (usually silver) extinguisher they last about 1 minute More Or Less. A co2 extinguisher (normal size) about... 11 seconds Other ones usually 10 to 20 seconds.
If an extinguisher has been partially discharged, it should be recharged or replaced at once. Some extinguishers- notably the dry powder type, will begin to leak the propellant gas, and lose all pressure within a few days. This is due to powder preventing the release valve from fully seating. The amount of time the contents of an extinguisher will continue being expelled from an extinguisher when the extinguisher is "opened" to extinguish a fire depends on the size of an extinguisher and how the user chooses to employ it (continuous or in bursts). Most easily portable extinguishers will last for less than a minute if held open for continuous use.
Pull Aim Squeeze Sweep This acronym refers specifically to the steps which need to be taken in order to properly use a fire extinguisher. First you 'Pull' the pin in the extinguisher in order to unlock it; then you 'Aim' the nozzle towards the base of the fire with one hand, while holding the extinguisher in the other (doesn't matter which hand you use as long as you're comfortable holding it); then you 'Squeeze' the trigger to initiate extinguishing; and last you 'Sweep', so that while aiming at the base of the fire you are going steadily side to side as you extinguish!!! Hope this helps!!!
apparently, the answer is somehow yes. the fire extinguisher in the basement somehow exploded and the top of it where the trigger thing is went straight through the sheetrock of the ceiling!that had to be one strong strong explosion if it broke through the sheetrock. the question is: what made it explode? the thing probably was last serviced over 10-15 years ago!
A fire extinguisher requires routine maintenance and testing to ensure proper function during an emergency. The date, which is often found on a service tag attached to the extinguisher, will either indicate the date of the last test, or the date on which re-certification is required. For most areas in North America, Extinguishers in commercial buildings are to be inspected and re-certified annually, and extinguisher systems in food preparation/commercial kitchen areas semi-annually. In many cases, there is a chart on the flip-side of the service tag, which is to be signed monthly by a responsible person from wherever the extinguisher is installed. This person is often an in-house health and safety representative, who simply checks that the pressure gauge of the extinguisher is in the green or 'charged' zone, and that the extinguisher is accessible and visibly in good condition.
The best type of fire extinguisher for use on flammable liquid fires is a portable fire extinguisher that can extinguish every single class of fire as defined by EN3 (A-B-E-D-F), NFPA/ANSI/UL (A-B-C-D-K) standards. This class of extinguisher should also be capable of extinguishing, in the flammable liquids class (B), both polar and non-polar fuels (polar: alcohols, ethers and esters; non-pollar: gasoline, etc.). In-depth research will show that in the last 100-years only a new Technology known as FFC (Fire Fighting Catalyst) by FireStopper® has produced the only reliable, independently tested and rated, listed, all fire-class effective fire extinguisher that meets the above requirements and more. As an added bonus, this new water-based "Green" Technology is freeze resistant to -100°F (-73.3°C) without harmful anti-freeze additives usable in the harshest environments of the planet.
It is 75 rounds, which would last you about 20 seconds constant fire, and would cost maybe $1.
Most fire extinguishers discharge in less than 30 seconds if the valve is held open the whole time. Larger extinguishers last longer. Commercial extinguishers might run for several minutes, such as a foam system for filling an aircraft hangar.
