Halotron is a clean agent fire extinguishing agent that is used to put out fires without leaving behind residue or harmful byproducts. It is environmentally friendly and widely used in situations where water or other chemical agents may be damaging or ineffective.
You would not want to use a pressure water extinguisher on any electrical fire due to the possibility of electricity being conducted through the water and injuring someone. A CO2, dry chemical or "clean agent" (e.g., "Halogenated") extinguisher would be a better choice for an electrical fire, knowing that dry chemical powder will make quite a mess.
No, compressed air should not be used to recharge a dry chemical fire extinguisher. These extinguishers require specific dry chemical agents that are designed for fire suppression, and using compressed air could compromise their effectiveness or damage the extinguisher. Recharging should only be performed by certified professionals using the proper materials and methods according to manufacturer guidelines. Always refer to the extinguisher's manual or consult a fire safety expert for proper maintenance.
Type A - water, Foam and dry chemical
You need to use a Class B extinguisher on flammable liquids.

Yes. They are rated for the type of fire they can be used against, and the capacity of the extinguisher.
A car extinguisher may be necessary for putting out several different types of fires, so it should be a Class A:B:C extinguisher, normally dry powder. For an irreplaceable classic, one might consider a CO2 or a "clean agent" extinguisher, to avoid the damage potential of dry powder chemical extinguishers.
The amount of fire retardant in a fire extinguisher varies depending on its type and purpose. For example, a standard 5-pound ABC dry chemical extinguisher typically contains about 5 pounds of dry chemical agent. Larger extinguishers, such as those used in commercial settings, can hold significantly more, ranging from 10 to 50 pounds or more. Always check the specifications on the extinguisher for precise details.
