Fire extinguishers of this type contain an ammonium phosphate base agent. Multipurpose agents are used in exactly the same manner as ordinary dry chemical agents on Class B fires. For use on Class A fires, the multipurpose agent has the additional characteristic of softening and sticking when in contact with hot surfaces.
Although many people look for only class A, B, or C fire extinguishers, there is an extinguisher that does the job of all three of these. ABC extinguishers are filled with a dry chemical agent known as mono ammonium phosphate and can fight all of these fires. This agent is corrosive and must be scrubbed off the surfaces once the first is out.
What type of fire extinguisher is harmful to human health?
Ammonium phosphate is the most often used ingredient in dry chemical fire extinguishers (with some ammonium sulfate). These chemicals can produce health problems linked with inhalation, such as upper respiratory irritation with symptoms such as coughing or chest tightness.
The type of fire extinguisher you need depends on the type of fire you need to put out: Class A Fires – fires caused by combustibles like wood, metal, cloth, paper, rubber, and plastics. Class B Fires – fires caused by flammable liquids like gasoline and grease. Class C Fires – fires caused by energized electrical equipment or wiring.

What type of liquid is used in fire extinguishers?
Water is the primary liquid used in these extinguishers, although sometimes other additives are also included. A drawback for pure water fire extinguishers is that it is not suitable for use in freezing conditions since the water inside will freeze and render the extinguisher unusable.
What are the different types of chemical fire extinguishers?
Types of agents available include sodium bicarbonate base and potassium bicarbonate base. Dry chemical type extinguishers have special treatments that ensure proper flow capabilities by providing resistance to packing and moisture absorption (caking). Fire extinguishers of this type contain an ammonium phosphate base agent.
What type of fire extinguisher should I use for lithium-ion battery fires?
A Class D fire extinguisher is your best bet when dealing with Lithium-ion battery fires. Class D fire extinguishers are required for combustible metals such as lithium, magnesium and potassium, which need a non-reactive medium to extinguish them. Water is ineffective when it comes to large Lithium fires like that of an electric vehicle fire.
What is the chemical extinguishing agent made of?
The extinguishing agent can be comprised of, but is not limited to, solutions of water and potassium acetate, potassium carbonate, potassium citrate, or a combination of these chemicals (which are conductors of electricity). The liquid agent typically has a pH of 9.0 or less.
