Growing research has shown that AFFF (aqueous film-forming foam) extinguishers contain Per- and polyfluoroalkyl substances (PFAS) chemicals, which are harmful to people, wildlife and the environment.
However, new fluorine-free fire extinguishers now exist, removing the need for use of harmful chemicals, whilst ensuring fires can be extinguished quickly and safely.
The Issue with PFAS
PFAS chemicals are a group of over 1,000 industrial chemicals found in a range of household items including clothing, food packaging and cleaning products, and can leak into the air, soil and water. Worryingly, studies show that they are now appearing in the blood, tissues and bones of people – further showing the vast issue that these chemicals present. Health issues that PFAS can lead to include cancer, liver damage, obesity and fertility issues, including growth and behavioural issues. However, there is a lack of research on some of the 1,000 chemicals, meaning effects are unknown.
Additionally, they can take up to 1,000 years to degrade under natural conditions, resulting in them decomposing into natural matter which contributes to carbon in the atmosphere, increasing air pollution and damaging the ozone layer.
PFAS in Fire Extinguishers
PFAS are found as an unintentional by-product in AFFF extinguishers. Foam extinguishers are a common choice of extinguisher, due to their foam control to suppress fires, and being resistant to high temperatures.
Previously, alternatives for AFFF extinguishers included water based, dry powder and CO2 extinguishers. But due to a demand for environmentally friendly solutions, foam fluorine-free options are now available, giving users the reassurance that their health and environment will not be harmed by their use, whilst remaining confident that performance will not be compromised.
PFAS Regulations
Some PFAS chemicals have been banned since 2020, with more regulations set to follow to eliminate PFAS, which could include AFFF. These restrictions have been made in the effort to phase PFAS out, meaning users should try to stay ahead of regulations and safeguard against risk now.
Fluorine-Free Extinguisher
CheckFire have launched their new CommanderEDGE enviroFoam fluorine-free fire extinguisher range.
Features
Class A and Class B Compatible
The new enviroFoam fluorine-free extinguishers work with both Class A (combustible materials) and Class B (flammable liquids) fires. With Class A fires, they work by promptly cooling burning material, acting as a wetting agent and giving considerable coverage. In Class B fires, extinguishers cover a layer of dense foam to create a blanket, cutting off oxygen supply, thus extinguishing the fire. Additionally, foam cools the fire to prevent reignition, adding another layer of protection.
Various Sizes
Three sizes of the enviroFoam fluorine-free extinguishers are available – 3 litre, 6 litre and 9 litre – allowing them to meet the needs of every size and site type.
Corrosion Resistant Finish
Both size extinguishers benefit from a corrosion resistant finish on their outside shell, encased in a steel cylinder. The interior also features an anti-corrosive layer.
Compliant
With Kitemark certification, these extinguishers assure dependability in manufacturing. They are also MER approved, meaning that they are suitable for safe installation in the UK marine industry.
Ease of Use
In an emergency event, it is vital that extinguishers are used rapidly, to minimise the spread of fire and its impact. EnviroFoam Fluorine-free fire extinguishers feature an accessible design, for easy and ergonomic operation.
Economical Maintenance and Service
Additionally, the design allows for maintenance and service, ensuring they are in working order and are fully operational, to ensure property and life are protected.
CheckFire Green Range
An increasing understanding of sustainability throughout the world is highlighting the need for alternatives to environment harming chemicals. CheckFire have created The Green Range, featuring products that have greener credentials.
Outlook
Although there are no current changes enforcing the end of existing foam extinguishers usage, there could be a possible ban on PFAS introduced in the coming years.The EU are enforcing a ban on per- and polyfluoroalkyl substances in fire extinguishers in 2030, with the UK likely to follow suite. Therefore, it is a good idea to consider switching to fluorine-free foam options, allowing you to stay compliant whilst protecting health and the environment.
