- Color Code: White.
- Use Cases: These extinguishers are perfect for areas where other extinguishers might leave harmful residue.
- Not to Use On: Water mist extinguishers are generally safe for most fires, but their effectiveness can vary. Always check the manufacturer’s guidelines before use.
6. Wet Chemical Extinguishers
- Description: Wet chemical extinguishers are specifically designed for Class F fires involving cooking oils and fats. They are also effective on Class A fires.
- Color Code: Yellow.
- Use Cases: These extinguishers are vital in commercial kitchens and food processing areas.
- Not to Use On: Wet chemical extinguishers should never be used on flammable liquid or gas fires or fires involving electrical equipment.
How to Use Fire Extinguishers
Knowing how to use a fire extinguisher properly is essential to controlling a fire before it spreads. Follow these steps to ensure you use the extinguisher safely and effectively.
1. Assess the Situation
Before acting, assess the situation to ensure the fire is small, contained, and not spreading. Always make sure that your escape route is clear and safe.
2. Alert Others
It is crucial to raise the alarm immediately to inform others in the area. Ensure that everyone evacuates the building, and call the fire department, even if you think you can manage the fire yourself.
Step-by-Step Guide on Using Extinguishers (P.A.S.S. Technique)
- Pull: Pull the pin at the top of the extinguisher to break the tamper seal.
- Aim: Aim the nozzle or hose at the base of the fire from a safe distance.
- Squeeze: Squeeze the handle to release the extinguishing agent.
- Sweep: Sweep the nozzle from side to side at the base of the fire until it seems to be out.
When Not to Use a Fire Extinguisher
In certain circumstances, using a fire extinguisher may not be the safest option. Here are some scenarios when you should avoid using one.
Do Not Use If:
- The fire is too large or spreading uncontrollably.
- The area is filled with smoke.
- You are unsure which type of extinguisher to use.
- Your escape route is blocked.
Evacuation Over Extinguisher Use
Always prioritize evacuation over trying to fight a fire. If the fire is beyond control or the extinguisher proves ineffective, leave the building immediately.
Fire Extinguisher Maintenance and Inspection
Fire extinguishers require regular maintenance and inspection to ensure they function properly in an emergency. Here’s what you need to know to keep them in good working order.
How Often and Why Extinguishers Need Servicing
Fire extinguishers must be serviced at least once a year by a qualified professional. Regular servicing guarantees that the extinguisher will function properly in case of an emergency.
Who Should Perform Inspections and Maintenance?
Only qualified professionals should handle servicing and maintenance. Additionally, a responsible person should conduct visual checks every month to spot any obvious damage or tampering.
Signs That an Extinguisher Needs Servicing or Replacement
- Physical Damage: Look for dents, rust, or leaks.
- Pressure Gauge: If the needle is outside the green zone, it could indicate overcharging or undercharging.
- Broken Seals: A broken or missing tamper seal or safety pin means the extinguisher may be compromised.
- Expired: Check if the extinguisher has exceeded its recommended lifespan.
Responsibilities of Business Owners and Premises Managers
Business owners and premises managers play a critical role in fire safety. Here are the essential responsibilities they must manage.
Risk Assessment
It is essential to conduct and document fire risk assessments regularly. This ensures that the correct type and number of fire extinguishers are available for each area of the premises.
Training
Owners and managers must ensure that all employees are trained in fire safety, particularly how to use fire extinguishers and the building’s evacuation procedures.
Maintenance
They must schedule regular professional servicing of fire extinguishers and ensure that monthly visual checks are conducted.
