In high-risk industrial environments, fire safety is a non-negotiable priority. One of the most important first lines of defense against fire is the proper use of fire extinguishers — but not all extinguishers are created equal. Understanding the types of extinguishers and their specific applications can make the difference between a small, contained incident and a costly emergency.
Why Fire Extinguisher Selection Matters
Different fuels require different extinguishing agents. Using the wrong type of extinguisher on a fire can be ineffective — and in some cases, even dangerous. In industrial settings where flammable materials, electrical equipment, and machinery are common, the right extinguisher can prevent injury, property damage, and extended downtime.
The Most Common Fire Extinguisher Types:
ABC Dry Chemical
Use for: Class A (ordinary combustibles), Class B (flammable liquids), and Class C (electrical fires)
Most versatile extinguisher for general use in industrial environments
Quickly suppresses fire by interrupting the chemical reaction
CO₂ (Carbon Dioxide)
Use for: Class B and C fires
Ideal for: Electrical rooms, server equipment, or flammable liquid storage
Leaves no residue — perfect for sensitive electronics
Water Mist
Use for: Class A fires
Benefits: Non-toxic, non-conductive, and safe for areas with people present
Often used in clean environments like labs or commercial kitchens
Foam
Use for: Class A and B fires
Common in: Fuel storage areas, machine shops, and areas with chemical use
Smothers fire and prevents re-ignition
Wet Chemical
Use for: Class K (cooking oils and fats)
Used primarily in: Commercial and industrial kitchens
Cools and reacts with oil to prevent reignition
