There are six classes of fires to define the type of fire, and most importantly, the type of fire extinguisher to use to put out the fire. Here are the fire classes and the types of extinguishers you should use: Class A - Solids (wood, paper, plastic) require water, foam, dry powder, and wet chemical extinguishers. Class B - Flammable liquids (fuel, oil, paraffin) require foam, dry powder, and CO2 gas extinguishers. Class C - Flammable gasses (propane, methane, butane) require dry powder extinguishers. Class D - Burning metals (aluminum, magnesium, titanium) require dry powder (M28/L2) extinguishers. Class E - Electrical items require dry powder or CO2 gas extinguishers. Class F - Cooking oils and fats require wet chemical extinguishers.
As long as your fire extinguisher has class k[cooking fire]labeled on the front.
ALL fire extinguishers are designed to put out fires. A Dry extinguisher uses a powder or gas rather than a liquid, and cuts off the oxygen to the fire. They can be used in freezing conditions where a water type extinguisher would be useless.
There really aren't impacts on the environment, unless you were to spray the Dry powder outdoors for no reason.

The white stuff in fire extinguishers is typically a chemical called dry chemical powder or monoammonium phosphate. This powder is a fire suppression agent that is effective for extinguishing different types of fires, such as those involving flammable liquids, gases, and electrical equipment. When released, the powder smothers the fire and helps to cool the fuel, preventing it from reigniting.
no they do not. they contain carbon dioxide, potassium bromide, and chalk. nothing in that is harmful.
Sufficient carbon dioxide would in theory douse the fire. Dry powder sodium bicarbonate is used in extinguishers this releases CO2.
Dry chemical fire extinguishers use a powder substance, such as sodium bicarbonate or monoammonium phosphate, to smother the fire and interrupt the chemical reaction. HCFC 123 fire extinguishers contain a clean agent called HFC-123, which is a halocarbon compound that extinguishes fires by removing heat and interrupting the chemical reaction. The main difference is in the extinguishing agent used, with dry chemical extinguishers being more versatile but leaving residue, while HCFC 123 extinguishers are cleaner and more suitable for sensitive equipment.
False class D which i think is dry powder can only be used on electrical fires.
Dry powder chemical is a form of chemical substance that is in a powdered or granular form and does not contain any liquid components. It is commonly used for fire extinguishers, as the dry powder composition helps to smother and extinguish fires by interrupting the chemical reaction that sustains them.
Because that is what the Dry powder (or Dry Chem.) is made for.
