A contract to incinerate foam containing fluorinated compounds has been called into question.
Funding supports assessment of firefighter exposure through multiple pathways.
A deluge-type fire suppression system had been accidentally activated.
Williams Fire & Hazard Control's Thunderstorm W813A is an aqueous film forming foam concentrate that combines flourocarbon and hydrocarbon surfactant to provide superior fire and vapor suppression for Class B, polar solvent, and hydrocarbon fuel fires.
Wisconsin state legislators voted Tuesday to tighten restrictions on the presence of per- and polyfluoroalkyl substances, referred to by some as "forever chemicals," in firefighting foam.
This fourth article in a series will address other water-based systems such as water spray, water mist, foam, and foam water.
Dynax's DX5011 is designed to be used in synthetic and protein-based alcohol-resistant firefighting foam agents such as AR-AFFF (Alcohol-Resistant Aqueous Film Forming Foam) and AR-FFFP (Alcohol-Resistant Film Forming Flouroprotein).
Foam chemistry is a delicate balancing act. A large component of this year’s Xtreme Industrial Fire & Hazard Training conducted at Brayton Fire Training Field involved acquainting industrial firefighters with the conflicting factors that make new fire foams difficult to develop.
Contamination issues at fire training facilities (particularly airports and defense sites) from intensive training use over decades, is raising government pressure, and focusing attention on the environmental costs of legacy PFOS and PFOA usage.
An internal floating roof's purpose is to create a seal between the tank and the atmosphere. Sealing a tank leaves no gap through which to distribute foam. Foam can be pumped in through a manhole.
