Fire Extinguisher Instructions:
Considerations Before Tackling A Fire
Fire extinguishers are designed to be as simple to operate as possible and you will find some basic fire extinguisher instructions on all appliances. Given the situations in which a fire extinguisher will be used, however, there are still some dangers involved so some guidance can be useful.
In the workplace, legislation requires that all staff should be properly trained in the action they need to take in the event of fire. This means that everyone needs to understand the emergency procedures with regard to fires, including whether or not they should use fire extinguishers. There should be clear guidance for all staff about who can operate fire extinguishers and in what circumstances. Staff who are required to operate fire fighting equipment should be given proper fire extinguisher training.
The following guidelines are a good basis for assessing whether it is appropriate to use a fire extinguisher or not:
- do not attempt to tackle a large or well established fire
- do not tackle a fire that has already produced lots of smoke. Smoke is poisonous and is what kills the majority of people who die in fires.
- before you tackle any fire, ensure you have a safe escape route. Don't allow the fire to come between you and your exit route.
- If at all possible, keep someone else with you, in case you need assistance or someone to get help.
- if the fire has spread rapidly, or it is starting to, give up and get out.

How To Use A Fire Extinguisher Safely
There is a well known acronym to help you remember the basic safety rules for using the most common types of fire extinguisher:
PASS: Pull, Aim, Squeeze and Sweep
- PULL out the pin in the top of the fire extinguisher.
- AIM the nozzle at the base of the fire.
- Stand about eight feet from the fire and SQUEEZE the fire extinguisher handle to discharge it. Release the handle again to stop.
- SWEEP the nozzle back and forth across the lower part of the fire. Watch carefully after extinguishing the fire in case it re-ignites.
Fire Extinguisher Instructions:
When NOT To Use A Fire Extinguisher
- If the fire is spreading rapidly. Only consider using a fire extinguisher if the fire is in the early stages.
- If you are not sure what is actually burning. Without knowing this you cannot be sure of using the correct fire extinguisher.
- If you do not have the proper fire extinguisher. Using the wrong type of fire extinguisher can be very dangerous in certain circumstances. For example, using a water fire extinguisher on an electrical fire can result in electrocution and possible death.
- If there is already a lot of smoke. Never risk inhaling smoke – you could be overcome very quickly. Many materials produce highly toxic gases.
Fire Extinguisher Instructions:
How To Use A Water Fire Extinguisher
Warning
Do not use on electrical fires of burning oil or fat.
How To Use- Direct the jet of water at the base of the fire and move it back and forth across the fire.
- Ensure all areas of the fire are out and check for hot spots after it appears to be extinguished
- If the fire is spreading vertically, start at the lowest point and work upwards.
Fire Extinguisher Instructions:
How To Use A Carbon Dioxide Fire Extinguisher
Warning
Do not use on burning deep fat fryers. Carbon dioxide extinguishers are not very effective at cooling fires, so check carefully afterwards in case of re-ignition. Carbon Dioxide is harmful in quantity, so care must be taken if used in a confined space. Ensure that the area is well ventilated as soon as possible after use. Take care not to hold the discharge horn as this can become very cold.
How To Use
- Direct the horn at the base of the fire and move across in a sweeping motion.
- When the fire appears to be out, check for a while afterwards for any areas of remaining fire and use the extinguisher again if necessary.
Fire Extinguisher Instructions:
How To Use A Foam Fire Extinguisher
Warning
Do not use on deep fat fryer fires. On burning liquids do not aim the foam directly into the liquid as this will send it into the liquid and make it ineffective. It could also cause splashing and therefore spread the fire around.
How To Use
- Where the burning liquid is inside a container, direct the jet of foam at the inside edge of the container or another vertical surface joining onto the container. This breaks the jet and allows the foam to flow gently over the surface of the liquid, smothering the fire.
- If the above is not possible, the jet of foam should be directed from a distance in a sweeping motion so that it drops down onto the surface of the fire without breaking it up.
Fire Extinguisher Instructions:
How To Use A Dry Powder Fire Extinguisher
Warning
Powder fire extinguishers are very versatile, but they do not cool fires very effectively, or penetrate electrical equipment very well, so there is a danger of fires starting up again after they appear to be out.
How To Use
- for fires on solid materials aim at the base of the fire and sweep across the fire in a steady motion.
- On fires involving liquids in containers or spilt liquids, the jet of powder should be directed at the nearest edge of the fire, and a sweeping motion used to work backwards from there.
- If the fire involves a flowing liquid, direct the jet at the base of the flames and sweep upwards.
- Before using on electrical fires, disconnect the power supply.
- When the fire appears to be out, allow the area to clear and check for any areas of remaining fire and use the extinguisher again.

How To Use A Wet Chemical Fire
Extinguisher
Warning
These are the only type of fire extinguishers that should be used on deep fat fires.
How To Use
- use the extended applicator or lance to apply the chemical in a slow circular movement.

Final Thoughts
If In Doubt:
- Do not tackle the fire if you are not confident about how to do so.
- Make sure that someone has called the emergency services.
- Put your own and other people's safety first – make sure everyone gets out.
- Never attempt to move anything which is on fire.
Follow these basic fire extinguishers instructions and you should be aware of the most important features of how to use a fire extinguisher safely. Proper fire extinguisher training is recommended for staff who are expected to know how to use a fire extinguisher as part of their job.
