There is no single fire extinguisher which works on all classes of fire. What are the different classes of fire?

Lithium-ion battery fires are a growing problem. As they are used in portable devices, electric vehicles, e-bikes and e-scooters, and renewable energy storage systems, there is an increasing number of fires being linked to lithium-ion batteries. If a battery goes into thermal runaway, the chain of events that follows is smoke, explosion and fire. In all cases, it is recommended that users should never leave li-ion battery-based devices on charge when out of the house or in communal areas. When dealing with Lithium-Ion battery fires, water-based extinguishers will provide an essential cooling effect, but they are not able to form a thermal barrier around the fire. When you run out of water-based extinguishant, you’ve run out of fire suppressing power. The battery forms its own flammable gases (including oxygen) and heat, and will re-ignite, burning until the cell fully discharges its energy. Aim: Aim low, pointing the nozzle or hose at the base of the fire. (Do not touch the horn on a CO2 extinguisher since it becomes very cold and can damage skin.Powder is completely ineffective, as it has no cooling effect, and will not cling to vertical surfaces of the cell. water is an electrical conductor, making the extinguisher unsuitable if the class of fire has an electrical supply, or for use near live electrical equipment. Fire extinguishers should ideally only be used by someone who has been trained to do so – and the following text does not count as training. Moreover, a fire extinguisher should only be activated once the fire alarm has been triggered and you have identified a safe evacuation route. Evacuate the building immediately if you still feel unsure about using a fire extinguisher or if doing so is clearly the safest option.

Do not move forward unless it is safe, and you should always remain at least one metre from the fire When choosing the right fire extinguisher, it is important to know that no single type of fire extinguisher can be used on all types of fires. Your fire risk assessment should identify which types of fires are most likely to occur in your building/premises, making this a good place to start. In 2017, it was reported that nearly four in 10 construction workers were using the wrong type of fire extinguisher to deal with electrical fires – a survey revealed. In addition, electrical fires have become more common causes of fire due to a greater reliance on electrical products and batteries. In 2021, electricity was the top reported cause of fire (19%) according to a fire industry survey, so it’s important to know which extinguishant should be used. These fire extinguishers and agents are intended for use on Class D fires and specific metals, following special techniques and manufacturer’s recommendations for use. The extinguishing agent can be applied from a fire extinguisher or by scoop and shovel. Using a scoop or shovel is often referred to as a hand propelled fire extinguisher. Water mist extinguishers are a type of water fire extinguisher that uses distilled water and discharges it as a fine spray instead of a solid stream. Water mist extinguishers are used where contaminants in unregulated water sources can cause excessive damage to personnel or equipment. Typical applications include operating rooms, museums, and book collections.the solution used in wet chemical extinguishers is alkaline, which means it can cause corrosion of some metals. produces a foam that acts initially as a blanket, covering the surface area and smoothering the fire. Foam extinguishers work similarly to water extinguishers by having a cooling effect on the fuel. The foaming agent works by creating a barrier between the flame and the fuel.
