Fire extinguisher

With a nearby fire extinguisher, you can quickly intervene if you notice a fire. It can make a big difference if you can extinguish the fire quickly. The difference can be between a small fire to a large spread in a short time if no one is acting. If you have no fire extinguisher ready, then it can be a disaster.

A fire extinguisher is used to extinguish smaller fires that have not yet grown up. There are some different fire extinguishers that you use in slightly different situations. These are divided into four different classes, A, B, C & D. Contact us at Safeguard, and we will help you choose your fire protection.

The legislation on fire protection differs from activity to activity. We at Safeguard help you find a solution that provides optimal security.

How is a fire extinguisher used?

Fire extinguishers should be easy to use for everyone at different ages when the accident occurs. It should also be clearly visible and easy to obtain. Below you see a checklist of how a fire extinguisher should be used.

  1. Pull out the fuse from the extinguisher     
  2. Loosen the hose     
  3. Try to stay under the smoke, and do not go closer to the fire than you need
  4. If it’s burning out, then think about how the wind blows, have the wind in your back     
  5. If it burns indoors, be sure to stay away from the smoke. There will also be more smoke as soon as you have started to extinguish the fire.
  6. Never take risks when it comes to fire. Rather go from there and close the door to the fire.
  7. A fire extinguisher can be worn around, but it should always stand up when you use it.     
  8. Press the trigger and try to extinguish the fire from the bottom up.
Water extinguishers A

A water extinguisher is mainly used to extinguish glow fires in, for example, fabric, paper, and wood, and is suitable for use in smaller fires. They are also frost-sensitive and should be stored indoors.

It takes about 20-30 seconds for the extinguisher to be emptied, and the throw length is about 4-5 meters.

It is good to avoid using it on, e.g., petrol or other petroleum products as it does not work well on these substances. Never use water to extinguish grease or oil, as this is directly fatal. Another thing to keep in mind is that water is live and not to be used on electronics.

Carbon dioxide extinguisher B

A carbon dioxide extinguisher is a gaseous extinguishing agent that penetrates the air and suffocates the fire. This fire extinguisher fits well in restaurant kitchens as it extinguishes fires in oils. Unfortunately, these extinguishers are ineffective as it takes about a six-kilo extinguisher to extinguish a small fire in, for example, a deep fryer.

The advantage is that the carbon dioxide is a pure extinguishing agent which does not leave any traces behind and does not lead to power. Therefore, it also fits well in cleaner environments such as laboratories.

The extinguisher has a very short throw length, so you need to get close to what´s burning to succeed in extinguishing the fire. The throw length is only 1-3 meters. It is also very wind sensitive and is not recommended for outdoor use. The extinguishing agent is -79 degrees, so the user must be careful not to touch the skin.

Foam fire extinguisher

Foam extinguisher is suitable for use in cultural environments when they mainly consist of water. The extinguisher should always be stored indoors as the foam does not withstand frost. It can be used against fires in fibrous material such as paper, wood, textiles. It can also be used for flammable liquids such as gasoline and oil.

It is not suitable for quench water-soluble liquids such as alcohol and acetone. The throw length for these extinguishers is 4-5 meters, and the emptying time is 30-35 seconds for a six-liter container.

A foam extinguisher is less suitable for electrical matters. If you still need to use the extinguisher for this, try to pull out the cord to the appliance that burns to reduce the risk of power transmission.

Powder Extinguisher ABC

Powder extinguishers are the most common and the best extinguisher for individuals. It is available in different sizes 2, 4, 6, 9, and 12 kilos. It takes different time to empty them, ranging from 10–30 seconds depending on your size.

A powder extinguisher extinguishes all types of fires and has a good range. When compared to the other hand, fire extinguishers, a powder extinguisher, have the best extinguishing effect per kilogram of extinguishing agents. Powder extinguisher does not lead to power, and therefore it is excellent even to extinguish electrical items. They work just as well both outside and inside as they are not frost-sensitive. They can also be used with advantage in cars and boats. But unfortunately, powder extinguishers are soiled and can be difficult to remove.

A powder extinguisher can work for up to 15 years if it is checked regularly and is dry. The Swedish Consumer Agency recommends that all fire extinguishers are checked every five years. Keep the fire extinguisher visible so you can easily access it if necessary.

One important thing to keep in mind is that a fire extinguisher can only be used once, then it must be recharged. It does not matter if you have sprayed a little or a lot. It still needs to be reviewed.

Fat extinguisher F

A fat extinguisher is recommended for restaurants and hotels. They are filled with extinguishing fluid that is good to use on burning oil and fat. These fires should never be extinguished with water as it can be extremely dangerous! The fat that burns can actually reach a temperature of 400 degrees. If you pour water on burning oil, the red-hot oil is thrown in all directions as an explosion.

If you are going to use a fat extinguisher, then it is good if you have gloves. You also need to walk close to the fire to extinguish it when the extinguisher has a short throw length. Burning fat is also a little tricky as it can self-ignite again at 330-340 degrees. Therefore, one must be vigilant and keep track of the oil or fat and make sure it is properly cooled.

Environmental extinguisher

An environmentally friendly fire extinguisher with effective fire protection.

Flour surfactants used in common fire extinguishers have been shown to remain in nature several years after emission. Therefore, work is now underway to reduce the use of this substance.

A hand fire extinguisher with foam extinguishes fires with a liquid such as oil and gasoline. These fire extinguishers have always contained fluoride to extinguish a liquid fire.

An environmentally friendly flour freeze is very effective and has the capacity to extinguish liquid fires. It is completely free of solvents and fluoride surfactants but is still very effective as a fire extinguisher.

In a regular fire extinguisher, foam liquid and water are mixed. The environmental extinguisher is built in a special way where the foam is in a separate container and mixed with water only when you use the fire extinguisher. This means that the extinguishing effect and the environmental impact will be much better than with the pressure-charged models.

Since the environmental extinguisher is now mixed with water and foam, you always have very high extinguishing power, and the life of the foam becomes many times longer.

Make regular checks on your fire extinguishers

  • Carefully check that your fire extinguisher has a whole hose     
  • Also, make sure that the extinguisher is full and has no visible damage 
  • Gently tap the gauge glass to make sure the gauge is working and not jammed.     
  • Also, check that the pressure gauge is green.     
  • Also, make sure that the seal remains

    Every year, rescue services in Sweden pull out about 10,000 fires in buildings. 60% of the efforts against building fires occur against housing, 20% against public buildings, and the rest against industries and other buildings.
