BC Fire Extinguishers (Dry Chemical) & Purple K Fire Extinguishers

BC fire extinguishers (dry chemical) are specifically designed for Class B and C fires. The extinguishing agent used is sodium bicarbonate. Purple K fire extinguishers are a high-performance version of class BC extinguishers that are extremely effective at knocking down fires. They use potassium bicarbonate as the extinguishing agent.

  • Oil and gas refineries
  • Mining operations
  • Airports
  • Naval ships
  • Military facilities
  • Service stations

Class B fires include flammable liquids like gasoline and oil, as well as flammable gasses. Class C fires include those caused by and including energized electrical equipment, such as appliances, and computers.

BC Fire Extinguishers are used for both Class B and C fires. Class B fires involve flammable liquids such as oil, alcohol, gasoline, and flammable gasses. Meanwhile, Class C fires are caused by energized electrical equipment appliances; these include fires related to power source connections, such as computers or appliances.

The two types of BC fire extinguishers are Dry Chemical extinguishers and Purple K fire extinguishers. Dry chemical extinguishers use sodium bicarbonate to extinguish Class B and C fires, and Purple-K extinguishers are higher-performance extinguishers that use potassium bicarbonate to extinguish fires more effectively.

No, Purple-K is a high-performance BC fire extinguisher that uses Potassium Bicarbonate to extinguish fires more effectively than a regular dry chemical extinguisher (sodium bicarbonate). It can be used for Class B: flammable liquids and gas fires, or Class C: energized electrical equipment fires.
