Process

A process for the production of carbonate based dry fire extinguishing agent

Area

Extinguish the BC type fire

Uses

This product is used for Extinguish the BC type fire

Dry Chemicals (carbonate based) are one of the most widely used type of fire extinguisher that are effective mainly on Class B and C fires. This agent works by evolving carbon-dioxide and eliminates oxygen from fire and replacing it with carbon dioxide.
