Typical Usages:
 
BC or "Regular" dry chemical extinguishers use a siliconized sodium bicarbonate based dry chemical to extinguish Class B — flammable liquids and Class C — electrically charged fires. They are best suited for use in places such as garages, light manufacturing plants and warehouses where appreciable quantities of flammable liquids are present, and/or areas where wiring or appliances are present.
