Usually nothing. But the extinguisher should be checked once a month to see if it is holding a charge.
Dry dust of mono ammonium phosphate
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.
Sodium chloride dry powder
DCP fire extinguishers use dry chemical powder as the extinguishing agent, typically composed of monoammonium phosphate. This powder effectively interrupts the chemical reaction in the fire by smothering the flames and preventing re-ignition. DCP extinguishers are suitable for Class A, B, and C fires, making them versatile for various types of fires.
Blood is not an effective extinguishing agent for fires. Water, foam, or chemical fire extinguishers are typically used to put out fires.
Nitrogen is preferred over carbon dioxide as a propellant in DCP (dry chemical powder) fire fighting systems because nitrogen is an inert gas, which means it does not react with the chemicals in the dry powder. This ensures the stability and effectiveness of the fire extinguishing agent. In contrast, carbon dioxide can react with some dry chemical powders, potentially reducing the extinguishing efficiency of the system.
The grainy insoluble substance in a fire bucket is typically sand or a fire extinguishing agent like dry chemical powder or foam. These substances are used to smother fires by cutting off the oxygen supply.
A Class D fire extinguisher is recommended for extinguishing a metal fire.
HCFC 123 is the raw base material use to produce a halogeanated, safe/effective and environment friendly fire extinguishing chemical agent called "halotron I". It was introduce in early 1990's to replace the "banned" fire extinguishing agents like, Halon 1211 and BCF's, which were found to have a severe ozone depleting potentials. In contrast, hcfc 123 base fire extinguishing agents has a near zero ozone depletion potentials.
water, carbon dioxide, dry chemical, and halogenated hydrocarbons.
A Class A fire extinguisher is recommended for extinguishing wood fires.
Most powders found in the kitchen will actually cause a fire to explode out of control. Let's say, "No" to your question, and direct you to use baking soda, which is safe and will smother a fire.
