Here OTEN Maritime studies show you how a hose team can get close enough to a fire, whilst effectively protecting themselves from a fire in order to put it out with a dry powder extinguisher.
something you have to be careful of is in the US dry powder is for metal fires dry chemical powder might be multi purpose or only liquid for liquids and electric!
This works great with BC and Purple K, but ABC is a single use powder, It should be used alone. ABC Powder is designed to melt and cling to burning surfaces it does not work well with water.
