Fire safety is crucial, especially in commercial kitchens and food establishments where the risk of cooking oil fires is high. One of the most effective tools for dealing with such fires is a wet chemical fire extinguisher. Unlike other extinguishers, this type is specifically designed to tackle Class F fires, which involve flammable cooking oils and fats. The fire protection Sydney experts will walk you through how to use a wet chemical fire extinguisher safely and effectively to control a fire before it escalates.
What is a Wet Chemical Fire Extinguisher?
A wet chemical fire extinguisher is specially designed to put out fires caused by deep fat fryers, cooking oil, and grease. It contains a potassium-based solution that reacts with burning oil, forming a foam-like barrier that cools the flames and prevents reignition.
These extinguishers are primarily used in commercial kitchens, restaurants, and food processing facilities, making them an essential part of any fire protection equipment order for businesses dealing with high-risk cooking environments.
When to Use a Wet Chemical Fire Extinguisher
This extinguisher is specifically for:
- Class F Fires – Fires involving cooking oil or grease.
- Some Class A Fires – Involving solid combustibles like wood or paper (though not the primary use).
It is not suitable for electrical, gas, or metal fires.
Step-by-Step Guide to Using a Wet Chemical Fire Extinguisher
Using a wet chemical extinguisher correctly is vital to ensuring fire safety. Follow these steps suggested by fire services in Sydney carefully:
Step 1: Assess the Fire and Evacuate if Necessary
Before using any fire extinguisher, assess the situation. If the fire is too large or spreading rapidly, evacuate immediately and call the fire department. Never attempt to extinguish a fire if it has reached an uncontrollable stage.
Step 2: Identify the Correct Fire Extinguisher
Confirm that you are using a wet chemical fire extinguisher (usually marked with a yellow label). Using the wrong extinguisher, such as a water or CO₂ extinguisher, on an oil fire can be dangerous and make the fire worse.
Step 3: Follow the PASS Technique
To use the extinguisher effectively, follow the PASS method:
- Pull the Pin – This unlocks the extinguisher and prepares it for use.
- Aim at the Base of the Fire – Point the nozzle at the lowest part of the flames, not at the top.
- Squeeze the Handle – Release the extinguishing agent steadily.
- Sweep Side to Side – Move the nozzle in a sweeping motion to cover the entire fire area.
Step 4: Apply the Wet Chemical Agent Gently
Unlike other extinguishers, the wet chemical should be applied in a controlled manner to avoid splashing hot oil. Hold the nozzle at a safe distance and apply the agent slowly to smother the fire and cool the oil.
Step 5: Wait and Observe
After applying the wet chemical solution, wait for a few minutes to ensure the fire does not reignite. The cooling effect of the extinguisher helps prevent re-ignition, but if the flames persist, repeat the process or seek professional help.
Step 6: Call for Professional Assistance
Even if the fire appears extinguished, contact emergency services or fire protection companies in Sydney to inspect the area. If you obtained the extinguisher from fire extinguisher suppliers near me, they might offer inspection and recharging services.
Safety Tips When Using a Wet Chemical Fire Extinguisher
- Do not use water – Water can cause burning oil to splatter, worsening the fire.
- Maintain a safe distance – Stay at least one meter away while using the extinguisher.
- Ventilate the area after extinguishing – To clear out smoke and extinguisher residue.
- Regular maintenance – If you source extinguishers from fire extinguisher companies, ensure they offer regular fire maintenance in Sydney.
Proper Storage and Maintenance
For businesses, keeping fire extinguishers in optimal condition is crucial. If you purchase from a fire extinguisher wholesale supplier, ask about regular maintenance, refilling, and inspections. Properly stored and well-maintained extinguishers ensure safety and compliance with fire safety regulations.
