Fire Safety Flashcards

Fire Safety Basics

• Fire Triangle: Composed of Heat, Fuel, and Oxygen; essential for fire ignition and sustenance.
• Extinguisher Function: Contains agents to eliminate one element of the fire triangle, effectively putting out the fire.

Fire Extinguishers Overview

• All Purpose Fire Extinguisher: Effective against Classes A, B, and C fires; discharges in 8-10 seconds; should be positioned 8-10 feet from fuel sources.
• Class K Fire Extinguisher: Combat Class K fires with a potassium acetate foam; lasts up to 40 seconds; used from a distance of 10-12 feet.

Classifications of Fires

• Class A: Common fires from ordinary materials (wood, paper, plastics); identified by a green triangle; water is the primary extinguishing agent.
• Class B: Involves flammable liquids and gases; represented by a red square; requires foam, CO2, dry chemicals, and sometimes water fog.
• Class C: Electrical fires denoted by a blue circle; best extinguished with CO2 and dry chemical extinguishers.
• Class D: Fires from combustible metals (magnesium, sodium, etc.); indicated by a yellow star; specialized techniques needed, as common extinguishers may exacerbate the fire.
• Class K: Involves cooking oils and fats; extinguished with low pH foam to cool and smother flames.

Fire Characteristics

• Electrical Fires: Most common industrial fire type; require appropriate extinguishing methods.
• Extinguishing a Fire: Achieved by smothering (depriving oxygen), eliminating fuel, or using an extinguishing agent effectively.

Fire Safety Protocols

• Pull: Pull the pin of the extinguisher before use.
• Aim: Target the base of the fire for effective extinguishing.
• Squeeze: Squeeze the handle to release the extinguishing agent.
• Sweep: Sweep the nozzle at the base of the fire to ensure complete coverage.

Preventative Measures (PMs)

• PM 1: Maintain tidy workspaces free from clutter to reduce fire hazards.
• PM 2: Be aware of the chemicals in your area and understand their handling and storage, referencing the MSDS binder.
• PM 3: Familiarize yourself with fire emergency procedures and your expected actions.
• PM 4: Contact professional help immediately to prevent fires from escalating.
• PM 5: Know REG's emergency action plan for fires and locate the Emergency Procedures Booklet for guidance.
