The first step is to look at what materials are present in the area to be protected from fire. These can be divided into six fire classes involving different substances: Fires in combustible metals, such as magnesium, titanium, zirconium, sodium, lithium, and potassium. Choosing fire extinguisher types for the relevant class of fire could literally be the difference between life and death. So here’s a useful guide on how to choose the right type and class of fire extinguisher for the appropriate scenario, including colour codes, fire classes and uses. The principal advantage of Carbon Dioxide (CO 2) fire extinguishers is that the agent does not leave a residue after use. This can be a significant factor where protection is needed for delicate and costly electronic equipment. Other typical applications are food preparation areas, laboratories, and printing or duplicating areas. Carbon dioxide extinguishers are listed for use on Class B and Class C fires. Because the agent is discharged in the form of a gas/snow cloud, it has a relatively short range of 3 ft to 8 ft (1 m to 2.4 m). This type of fire extinguisher is not recommended for outdoor use where windy conditions prevail or for indoor use in locations that are subject to strong air currents, because the agent can rapidly dissipate and prevent extinguishment. The concentration needed for fire extinguishment reduces the amount of oxygen in the vicinity of the fire and should be used with caution when discharged in confined spaces.

Powder is completely ineffective, as it has no cooling effect, and will not cling to vertical surfaces of the cell. Specialist lithium-ion battery fire extinguishers should contain Aqueous Vermiculite Dispersion (AVD). This extinguishing agent is made up of Vermiculite particles chemically suspended in water, discharged in a fine mist which provides both a cooling effect and forms a heatproof barrier around the burning battery cell to prevent propagation and re-ignition. Vermiculite has strong thermal insulation properties and therefore prevents heat transfer from the burning cell to its surroundings. How to use a fire extinguisher This type of extinguisher is most suitable for class B and electrical fires. They contain pure, compressed CO 2 (carbon dioxide) gas which is discharged through a horn as a strong jet of gas. These are often the most popular choice of fire extinguisher, and work by starving the fire of oxygen and therefore putting it out.Electrical fires - electrical equipment: once the electrical item is removed, the fire changes class The five different types of portable fire extinguishers are water, powder, foam, wet chemical and carbon dioxide (CO2). There are as many as 15 if you count the supplementary portable fire extinguishers. Anyone who may have to use a portable fire extinguisher should be trained by a professional to do so. carbon dioxide is a non-conductor, so can be used on live electrical equipment (so is often suitable for server rooms). Fires in cooking appliances that involve combustible cooking media (vegetable or animal oils and fats). There is no single fire extinguisher which works on all classes of fire. What are the different classes of 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. Disadvantages are that the powder does not soak into materials and does not have an effective cooling effect on the fire, which can result in the fire reigniting. The powder is hazardous if inhaled, so they should be used in well-ventilated areas and are not suitable for offices and domestic premises. The powder damages soft furnishings, machinery, etc, and needs a lot of cleaning up after use. They cannot be used on chip pan fires (Class F). the fire extinguisher fire rating for class B, C, F and electrical fires is lower than other types of fire extinguisher aligned with this class of fires. 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.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. 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. Our monthly member e-newsletter keeps you informed of current industry issues and legislative changes, as well as forthcoming events and webinars, and podcast releases. These contain only pressurised carbon dioxide gas and therefore leave no residue. Carbon Dioxide (CO2) extinguishers are used on fires involving burning liquids (Class B), and electrical fires, such as of large computer equipment, so are practical in offices. CO2 works by suffocating the fire and does not cause damage to the electrical items or cause the system to short circuit.

Keeping Everyone Safe Activity Ideas

AFFF (aqueous film-forming foam) and FFFP (film-forming fluoroprotein) fire extinguishers are rated for use on both Class A and Class B fires. As the name implies, they discharge a foam material rather than a liquid or powder. They are not suitable for use in freezing temperatures. An advantage of this type of extinguisher when used on Class B flammable liquid fires of appreciable depth is the ability of the agent to float on and secure the liquid surface, which helps to prevent reignition. 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. They work by cooling the fire and reducing the oxygen supply. These devices are likely to replace wet chemical extinguishers for the extinction of deep fat fryer fires, and leave no residue or collateral damage. Like water extinguishers, they are recyclable and do not contain any chemicals. However, they cannot be used on Class D fires (metals). Fires in flammable liquids, combustible liquids, petroleum greases, tars, oils, oil-based paints, solvents, lacquers, alcohols, and flammable gases.Keep collections to yourself or inspire other shoppers! Keep in mind that anyone can view public collections - they may also appear in recommendations and other places. A jet nozzle is eschewed in favour of a spray nozzle, which creates a fine spray courtesy of the higher pressure. Hitting a broader surface area this extracts heat more rapidly. Surfactants can be added to help the water penetrate further into burning material. Foam extinguishers (cream label) Smoke alarms are an absolute must for all households. One should be fitted on each floor of your home and they should also be periodically tested. Choose one with a test button that spares your ears by sounding the alarm at a reduced volume. Meanwhile, carbon monoxide detectors are essential to alert members of your household to the presence of this highly dangerous gas. even indoors, as soon as the CO 2 dissipates any remaining embers can start reignition of the fire.
