About this deal

To make life easy, most fire extinguishers also clearly state what they contain on this band. This is important to know as you need to keep the right fire extinguishers to hand, depending on what type of fire risk you face in any given area. Colour coding works as follows:

Most class F extinguishers contain a solution of potassium acetate, sometimes with some potassium citrate or potassium bicarbonate. The extinguishers spray the agent out as a fine mist. The mist acts to cool the flame front, while the potassium salts saponify the surface of the burning cooking oil, producing a layer of foam over the surface. This solution thus provides a similar blanketing effect to a foam extinguisher, but with a greater cooling effect. The saponification only works on animal fats and vegetable oils, so most class F extinguishers cannot be used for class B fires. The misting also helps to prevent splashing the blazing oil. 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) 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. Cold Fire is an organic, eco-friendly wetting agent that works by cooling, and by encapsulating the hydrocarbon fuel, which prevents it from entering into the combustion reaction. Bulk Cold Fire is used in booster tanks and is acceptable for use in CAFS systems. Cold Fire is UL listed for A and B fires only. [28] Aerosol versions are preferred by users for cars, boats, RVs, and kitchens. Used primarily by law enforcement, fire departments, EMS, and the racing industry across North America. Cold Fire offers Amerex equipment (converted 252 and 254 models) as well as imported equipment in smaller sizes. Before you try to extinguish a fire using any fire extinguisher, including the AFFF type, you should first make sure that you are not in danger. You should always have clear access to an escape route and you should never attempt to take on the fire if the flames are too big or if there is too much smoke.Prevents reignition: The Aqueous Film Forming Foam creates a thin barrier between the flames and the burning surface and smothers the fire, preventing reignition EN3 does not recognise a separate electrical class – however there is an additional feature requiring special testing (35 kV dielectric test per EN 3-7:2004). A powder or CO 2 extinguisher will bear an electrical pictogramme as standard signifying that it can be used on live electrical fires (given the symbol E in the table). If a water-based extinguisher has passed the 35 kV test it will also bear the same electrical pictogramme – however, any water-based extinguisher is only recommended for inadvertent use on electrical fires. As with water extinguishers, foam extinguishers have a cooling effect on the fuel. On burning liquids, the foaming agent creates a barrier between the flame and the fuel, extinguishing the fire.

It is important for you to consider many aspects when deciding which fire extinguisher best suits your workplace or any given environment. You will want to be covered for every eventuality, and with this in mind we have devised a guide to aid in your decision making process, detailing the most important things to know when selecting a fire extinguisher. Fire Classes Given that foam fire extinguishers primarily use water, using one on a Class F fire would worsen the fire rather than extinguish it.

Halocarbon replacements, HCFC Blend B (Halotron I, American Pacific Corporation), HFC-227ea (FM-200, Great Lakes Chemicals Corporation), and HFC-236fa (FE-36, DuPont), have been approved by the FAA for use in aircraft cabins in 2010. [30] Considerations for halon replacement include human toxicity when used in confined spaces, ozone depleting potential, and greenhouse warming potential. The three recommended agents meet minimum performance standards, but uptake has been slow because of disadvantages. Specifically, they require two to three times the concentration to extinguish a fire compared with Halon 1211. [31] They are heavier than halon, require a larger bottle because they are less effective, and have greenhouse gas potential. [32] Research continues to find better alternatives.

Dry Powder Extinguisher (Special Powders)

Specifications of fire extinguishers are set out in the standard AS/NZS 1841, the most recent version being released in 2007. All fire extinguishers must be painted signal red. Except for water extinguishers, each extinguisher has a coloured band near the top, covering at least 10% of the extinguisher's body length, specifying its contents. Deep fat frying is the biggest cause of cooking fires but can be caused by a variety of reasons, such as unattended pots and pans. CO 2, a clean gaseous agent which displaces oxygen. Highest rating for 20lb (9.1kg) portable CO 2 extinguishers is 10B:C. Not intended for class A fires, as the high-pressure cloud of gas can scatter burning materials. CO 2 is not suitable for use on fires containing their own oxygen source, metals or cooking media, and may cause frostbite and suffocation if used on human beings. produces a foam that acts initially as a blanket, covering the surface area and smoothering the fire. The good news is that portable fire extinguishers are effective and are saving lives. According to a survey from companies in the four main trade associations in the UK fire sector, the number of fires being successfully extinguished by portable devices has increased from 80% in 2003 to 93% in 2021.

Blue Fire Extinguishers – (dry powder) Which are safe for use on gaseous fires, flammable liquid and electrical fires, as well as paper, wood, and fabric firesSweep: Sweep from side to side at the base of the fire – the fuel source – until the fire is extinguished. even indoors, as soon as the CO 2 dissipates any remaining embers can start reignition of the fire. Also, if you don’t have the appropriate fire extinguisher training and you don’t feel confident in using the extinguisher, the safest choice is to evacuate the building alongside everyone else and let the firefighters handle the problem. After that, the foam fire extinguisher will require a regular annual fire extinguisher service by a qualified engineer, along with daily visual inspections by the fire marshal. 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.
