In this post, we break down OSHA fire extinguisher use and explore the different class types to ensure you're equipped for any workplace fire emergency.
Understanding Fire Extinguisher Types
Fire extinguishers are labeled by class (A, B, C, D), each designed for a specific type of fire. Choosing the correct extinguisher is crucial to safely suppress flames before they become unmanageable. Learn more about extinguisher classifications at femalifesafety.org.
Class A
Designed for ordinary combustibles like paper, wood, and cloth.
Class B
For use on flammable liquids such as gasoline, oil, and solvents.
Class C
Intended for electrical fires involving live wires, outlets, or equipment.
Class D
Used for combustible metals like magnesium, sodium, and aluminum.
Multipurpose extinguishers are labeled with multiple classes (e.g., A-B-C) and are effective for most fire types found in homes and workplaces.
Understanding which extinguisher suits which fire type gives you the confidence to act swiftly and safely in an emergency.
OSHA Standards for Fire Extinguishers
What Does OSHA Require?
Under OSHA standard 29 CFR 1910.157:
(c)(1): Fire extinguishers must be clearly identified and easily accessible.
(c)(3): The use of carbon tetrachloride or chlorobromomethane extinguishing agents is prohibited.
Choosing an OSHA-Certified Fire Extinguisher
When selecting an OSHA-approved fire extinguisher, be sure to:
- Choose the correct class for your potential hazards.
- Select a size that you can comfortably lift and use.
- Ensure the extinguisher is labeled as OSHA/UL approved.
How to Suppress a Fire: The P.A.S.S. Method
The P.A.S.S. method is taught in most workplace safety training courses:
- P - Pull: Pull the pin to break the tamper seal.
- A - Aim: Aim low, pointing the nozzle at the base of the fire.
- S - Squeeze: Squeeze the handle to release the extinguishing agent.
- S - Sweep: Sweep the nozzle from side to side at the base until the fire is out.
If the fire reignites, repeat the last three steps. Always ensure your property has working extinguishers and a backup plan like fire insurance in case of emergency.
