Firefighting foam is a type of chemical that is used for the suppression of fires. It cools the burning fuel and prevents it from coming into contact with oxygen. The invention of firefighting foam was credited to Russian engineer Aleksandr Loran, who first invented it in 1902. It can be found in most fire departments, and firefighters use it to put out home and building blazes. This article discusses its uses and history.

PFAS is a carcinogen that is absorbed through the skin and is known to increase the risk of cancer in firefighters. Fortunately, the use of PFAS-free firefighting foam is no longer required for municipal fire departments, which have been warned of the health risks of these chemicals. As a result, the Federal Aviation Administration (FAA) has now mandated its use. However, the New Hampshire Legislature has not taken any action to curb this threat.

PFOS and PFOA are two compounds that were used in AFFF in the past. The PFOS in AFFF manufactured by 3M Corporation prior to 2004 still contains this chemical. PFOS-based AFFF was phased out by U.S. manufacturers in 2002, but some still exist in other countries. PFOA is another chemical that was used in some foams, though it was largely phased out by 2015 due to the health risks. It is important to confirm with the manufacturer if the AFFF contains this substance.

PFAS-containing FirefightingFoam are still being used by U.S. military bases despite congressional orders to phase them out. Even after the military has been told to do so, it may take several more years to comply with the new regulations. While the military has banned the use of PFAS-containing firefighting foam, the government has not done much about this issue. There are still hurdles, but the market is paving the way for a more environmentally friendly foam.

Although the development of AFFFs has made advances in the past decade, there are still a number of concerns. PFASs have been linked to cancer and have limited shelf life. Some of these chemicals are not suitable for the environment. The PFAS-containing firefighting foams are now considered safe for use in the military. The use of firefighting foams is now legal in all 50 states. It is widely available in most chemical stores and fire stations.

The use of firefighting foams in municipal fire departments is limited. In the case of Class A fires, AFFFs are most often used for the suppression of fuel fires. Some of them contain fluorine, but they are not toxic. The use of PFASs in AFFFs is strictly regulated by the government. Some of these chemicals are deemed harmful to human health and the environment, so they are banned in municipal firefighting areas.
