Two in one / fire extinguisher

Two in one

“Two in one”is combining the functionality of a throwing fire extinguisher and powder extinguisher for existing and effective initial fire suppression activities. How to work a powder fire extinguisher to put out early fire suppression is that extinguisher powders are diffused around space by using a throwing fire extinguisher. Despite using a throwing extinguisher, if fire suppression isn’t complete, you can use powder extinguisher.
