Fire safety: Fire extinguisher use and selection

Fire extinguishers are the first line of defense in any fire. Knowing their locations and how to use them is crucial for safety and property protection on the jobsite.

Key Tips:

• Call 911: In the event of a fire, sound the alarm and call 911.
• Locate Extinguishers: Before starting work, identify the nearest fire extinguisher.
  • Travel distance to a fire extinguisher varies based on hazards, typically ranging from 30 to 75 feet.³
  • Ensure an appropriately sized and type-specific extinguisher is close to your work area, especially when dealing with flammable liquids or high-hazard tasks (e.g., hot work).
• Use the Right Extinguisher: Match the extinguisher type to the fire:
  • Class A: Wood, paper, many plastics, cloth
  • Class B: Flammable liquids, grease, gas, oils
  • Class C: Electrical fires
  • Class D: Combustible metals
• Understand Limitations: Be aware of extinguisher limitations in duration and range:
  • Smaller extinguishers may last 8-30 seconds¹.
  • Discharge range varies; many ABC dry chemical extinguishers have a range of less than 20 feet, with smaller ones under 10 feet².
• For Small Fires Only: Use extinguishers on small or incipient fires.
• Positioning: Always keep yourself between the fire and the exit to avoid being trapped.
• P.A.S.S. Method:
  • Pull the pin
  • Aim at the base of the fire
  • Squeeze the handle
  • Sweep side to side
