Acid can corrode the metal shell of the extinguisher. When it is rapidly pressurized, it may explode. They are no longer an approved extinguisher in many nations.
normally red, but different fires require different extinguishers which will vary in color.
The primary advantage of carbon dioxide (CO2) extinguishers over soda acid extinguishers is their effectiveness in suppressing fires without leaving a residue. CO2 extinguishers displace oxygen, smothering the fire, while soda acid extinguishers can leave behind a corrosive substance that may damage sensitive equipment. Additionally, CO2 extinguishers are suitable for use on electrical fires, whereas soda acid extinguishers are not recommended for such situations. This makes CO2 extinguishers more versatile and safer for various fire types.
Nitrogen can be used in fire extinguishers as gas propellant.
FIRE extinguishers are used to put out fire.
You can get fire extinguishers recharged at fire equipment companies, some hardware stores, and fire departments.
No, there are boats that do not need any fire extinguishers.
Fire extinguishers are best used on incipient (at the beginning) fires.
Some fire extinguishers are not directly pressurized, but have an external pressurized cartridge (or system of multiple cartridges) that is activated when pressure is needed. Also, in portable fire extinguishers, there may be either a pressure cartridge or a manual pump for some kinds of extinguishers. Another obsolete method (the soda-acid extinguisher) included a cylinder of sodium bicarbonate solution with a bottle of sulfuric acid, none of which was pressurized. When you inverted the extinguisher or pressed a plunger to spill the acid into the bicarb, the resulting CO2 gas would pressurize the container and blow the bicarb/water/acid solution out through the hose aimed at the fire.
In 1881, Almon M Granger patented a fire extinguisher which used the reaction between sodium bicarbonate and sulfuric acid to expel pressurized water. When the acid and bicarbonate mixed, carbon dioxide gas was released - which pressurized the water. These were still reasonably common up until the 1920s, but are not one of the common types of fire extinguishers used today.
Yes, fire extinguishers can be refilled by trained professionals to ensure they are ready for use in case of a fire emergency.
Class K fire extinguishers are designed to supplement kitchen fire suppression systems.
