FAQ
What type of fires are 500ml fire extinguishers suitable for?
These extinguishers are primarily designed for Class A fires – ordinary combustibles like wood, paper, and textiles. They may also offer limited effectiveness on Class B fires (flammable liquids) but shouldn't be relied upon as the sole solution for these types of incidents.
How long will a 500ml extinguisher last?
The duration of discharge varies depending on the specific model and the size of the fire, but most 500ml extinguishers will provide approximately 10-20 seconds of sustained spray. Always aim for the base of the flames and use short bursts to conserve the extinguishing agent.
What should I do if a 500ml extinguisher runs out?
If the extinguisher empties before fully extinguishing the fire, immediately evacuate the area and call emergency services (999). Do not attempt to re-enter the burning building under any circumstances.
How do I store my 500ml fire blanket?
Store your fire blanket in an easily accessible location – ideally near a heat source like the kitchen stove or within sight of escape routes. Ensure it's rolled loosely and hung on a hook or stored in a readily available container to prevent wrinkles that could hinder deployment.
What makes a good 500ml fire blanket?
Look for blankets made from inherently flame-resistant materials like fiberglass or treated wool. A tightly woven fabric will provide better protection, and a size of approximately 90cm x 90cm offers ample coverage for smothering small flames.
Can I use a fire blanket on an electrical fire?
While a fire blanket can help contain the spread of heat and flame from an electrical fire, it's crucial to ensure the appliance is switched off at the mains before attempting to cover it. Never touch exposed metal with a wet hand.
Are 500ml extinguishers suitable for use by children?
While these extinguishers are compact, they should always be used under adult supervision. Ensure children understand the correct operating procedures and that the extinguisher is stored out of their reach to prevent accidental activation.
What’s the best way to aim a 500ml fire extinguisher?
Direct the nozzle at the base of the flames, aiming for the fuel source rather than the flames themselves. Use short, controlled bursts to effectively suppress the fire and maintain your position relative to the heat.
How do I check my 500ml fire extinguisher before use?
Inspect the pressure gauge regularly – it should be within the green zone indicating sufficient pressure for operation. Also, verify that the nozzle is clear of obstructions and that the extinguisher remains undamaged during storage.
What if the extinguisher malfunctions?
Immediately evacuate the area and contact emergency services. Do not attempt to repair or disassemble the extinguisher yourself – leave this to qualified professionals. Refer to the manufacturer's instructions for reporting any issues.
