Can be used to extinguish ABC type fires
Certified by TIS 332-2537
Dry chemical powder is not a conductor of electricity, so it can extinguish class C fires. However, it should be considered, for example, if it is a computer lab, it should not be used because it will cause damage to electronic equipment due to its weak salt properties.
Dry chemical powder is effective in covering and extinguishing fires well because its dispersion has the effect of covering and extinguishing a lot of fires and it is heavier than air, so it can block oxygen in the air from reacting with fuels well.
Cheap, easy to find.
The cost of repackaging the substance is not very expensive.

Disadvantages

When sprayed, it will be a powdery dust, making the area of use dirty and difficult to clean.
There is a chance that the fire will flare up again, i.e. it will not be completely extinguished.
It is harmful to electronic devices.
It can be used only once. Whether it is used up or not, it must be filled with new extinguishing agent.
Chemicals should not be sprayed if the source of the fire is not visible because the powder will spread, causing eyestrain and making it impossible to see the source or exit. It may cause panic and run away, which is dangerous. Phosphate ion therefore has a longer service life and maintains its effectiveness for a long time.
