How To Avoid Contamination And Injury Risks From Aqueous Fire Fighting Foam (AFFF)
Safety concerns have been raised recently following a number of news stories linking fire fighting foam to cases of water contamination and personal injury. Although the incidents in question took place in the USA, they have provoked worry in the UK, where fire fighting foam is widely used by fire fighters, military and civilian businesses as well as airports and shipping.
What is the background to this story, and what are the dangers associated with fire fighting foam? In this article, we give an overview of the controversy and propose a way for you to avoid such risks in your own fire prevention strategy.
Is Aqueous Film Forming Foam (AFFF) safe?
AFFF is used throughout the USA by public firefighting departments, as well as by private business, offices and factories. It has historically been seen as a safe and effective fire suppressant, but two recent incidents at the Wright-Patterson Air Force Base have thrown this into question.
The first involved an injury to a firefighter during a training exercise on the base. Michael Strouse, an experienced firefighter, was injured when a fire fighting pipe burst and sprayed his face with high pressure fire suppressant. He immediately began to experience the symptoms of chemical burns, as well as difficulty breathing and sore eyes. The condition worsened over the following 24 hours, leading to Strouse being signed off work for three months.
At the same time, two drinking water wells on the base needed to be closed as result of suspected groundwater contamination from AFFF use. The two incidents have prompted a nationwide review of the use of AFFF fire suppressant by the US Defence Department, as there are concerns that the dangers are more widespread than currently recognised. Early reports from another Air Force Base in Colorado have suggested another link to groundwater contamination, indicating that there may be many more undiscovered cases.
Dangers to health and the environment.
The risk of personal injury after direct exposure to chemicals is something that all fire suppressant manufacturers must strive to reduce. However, environmental dangers from water contamination pose a much more widespread and insidious risk to human health. This is due to the potentially dangerous compounds contained in AFFF.
The most hazardous components are two perfluorinated compounds:
- Perfluoro-octane sulfonic Acid (PFOS)
- Perfloro-octanoic Acid (PFOA)
The AFFF tested in Colorado contained 20 times the recommended safe level of each of these compounds.
What are the health risks?
If leached into the water supply in sufficient quantities, perfluorinated compounds can cause a wide range of serious, long-term health risks. These include:
- A number of cancers, including kidney and testicular cancer.
- Increased cholesterol and obesity
- Thyroid disruption
- Ulcerative colitis
- Liver damage
- Complications in pregnancy leading to low birth weights in new-born babies.
These are clearly serious issues, and although there are other sources of perfluorinated compounds than firefighting foam, if water contamination is a risk, then any environmental release must be managed or controlled – better still prevented!
Impact in the UK.
So far, there have been no investigations into the safety of firefighting foam in the UK, but many businesses are pre-empting a possible investigation by reviewing the fire suppressant foams they use. And that’s not to say that there won’t be additional regulations introduced in the UK as a result of this. Environmental and health and safety regulations become more stringent with each passing year. Prevention is also better than cure, so it is far more cost-effective to pre-empt the risk of contamination and personal injury, rather than deal with it after the event.
