  2. Firefighting foam - Wikipedia

    en.wikipedia.org/wiki/Firefighting_foam

    Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, thus achieving suppression of the combustion . Firefighting foam was invented by the Moldovan engineer and chemist Aleksandr Loran in 1902.

    en.wikipedia.org/wiki/Perfluorinated_compound

    They are components of fire-fighting foam. [1] Fluorosurfactants (PFAS) reduce surface tension by concentrating at the liquid-air interface due to the lipophobicity of polyfluorocarbons. Chlorofluorocarbons are also perfluorinated compounds, many of which were formerly used as refrigerants until they were implicated in ozone degradation.

    Fire-fighting foam; Insect baits for control of leaf-cutting ants from Atta spp. and Acromyrmex spp. In 2019, it was decided to only keep one acceptable purpose: [71] Insect baits with sulfluramid (CAS No. 4151-50-2) as an active ingredient for control of leaf-cutting ants from Atta spp. and Acromyrmex spp. for agricultural use only

    Concerns have been raised that Phos-Chek harms fish and aquatic life; and that it causes long-term effects on soils, insects, and microbiology. [13] A group based in Oregon called Forest Service Employees for Environmental Ethics sued the U.S. Forest Service, claiming the service violated the Clean Water Act by spraying Phos-Chek without assessing the product's harmful effects on waterways.

    The source of contamination was later found to be a military fire-fighting exercise site in which PFAS containing fire-fighting foam had been used since the mid-1980s. [126] Additionally, low-level contaminated drinking water has also been shown to be a significant exposure source of PFOA, PFNA, PFHxS and PFOS for Swedish adolescents (ages 10 ...

  7. Fire retardant gel - Wikipedia

    en.wikipedia.org/wiki/Fire_retardant_gel

    The stacking of the bubblets is similar to aspirated fire fighting foam or compressed air foam systems, except that bubblets are water filled, whereas foam bubbles are only filled with air. Due to the high specific heat of water, it requires more energy to raise the temperature of water than air.
