BC agent is a sodium bicarbonate based dry chemical containing chemical additives, and is produced by an exclusive chemical process. The resultant agent is free-flowing, water repellent, non-abrasive, and when used as a fire suppressing agent, will produce no toxic effects. BC Dry Chemical is bluish-white in color to differentiate it from other dry chemical agents.

Post-fire cleanup of BC agent can be readily accomplished using a vacuum cleaner or a broom and dust pan.


BC Dry Chemical agent may be used to combat fires in flammable liquids, gases, and greases (Class B) including such fires when involved with energized electrical equipment (Class C). Specific applications include the protection of refinery applications and textile industry machinery.


On a pound for pound basis, BC agent is twice as effective in extinguisher applications as carbon dioxide. Various extinguishers charged with BC agent will function effectively at temperatures from –65 °F to 120 °F (–54 °C to 49 °C).


Never mix BC agent with phosphate based dry chemicals. A chemical reaction that is harmful to the extinguisher will take place, and may cause failure of the extinguisher.
