There are a number of different chemicals. The most common are... Monammonium phosphate, Potassium bicarbonate and Sodium bicarbonate (aka baking powder)
A type chemical fire extinguisher.
BC type Dry powder extinguisher is the hydrocarbon extinguisher since it is used for extinguishing hydrocarbon fires.
No it does not, but it may not be usable if the pressurized gas gets discharged.
Would not bet my life on an extinguisher that is nearly 30 years old. The mention of a test button indicates this is a disposable extinguisher. Get another- they are fairly cheap.
dry ether is generally used as solvent in chemical reactions. to the best of my knowledge there is no reaction where ether is used as a catalyst.
A type chemical fire extinguisher.
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.
BC type Dry powder extinguisher is the hydrocarbon extinguisher since it is used for extinguishing hydrocarbon fires.
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.
liquid and electrical fires.
dry powder
Because that is what the Dry powder (or Dry Chem.) is made for.
A dry powder fire extinguisher is mostly recommended for use in vehicles and in the home. So basically they are usually used for small fire emergencies.
basically in DCP (dry chemical powder) fire extinguishers mono ammoniumphosphate is used. but some more chemicals compound are also used e.g. sodium bicarbonate, potassium bicarbonate, pottasium chloride etc.
