What is 3% AFFF used for?
CHEMGUARD C3B 3% AFFF Concentrate is intended for use on Class B hydrocarbon fuel fires with low water solubility, such as crude oils, gasolines, diesel fuels, and aviation fuels.
Is AFFF banned?
The new law bans the use of PFAS-containing firefighting foam, or “AFFF,” effective October 1, 2021. The Task Force was first convened after the accidental release of PFAS from an aircraft hangar at Bradley International Airport.
What is the difference between AFFF and AR-AFFF?
Using plain AFFF concentrate as a base material, a high molecular weight polymer is added during the manufacturing process. When AR-AFFF is used on a polar solvent fuel fire, the polar solvent fuel tries to absorb water from the foam blanket.
Is AFFF a hazardous material?
AFFF constitutes a U.S. Occupational Safety and Health Administration hazardous material because of its physical hazards, such as skin and eye irritation. Discharge of wastewater and runoff containing AFFF on land, at sea, or to surface water bodies is also subject to regulation under the Clean Water Act.
How do you mix AFFF?
The low surface tension of the water-foam solution enables the aqueous film, although heavier than the burning liquid, to float on top of the liquid surface. Fomtec AFFF 1% A should be used at 1% proportioned solution (1 part concentrate in 99 parts of water) in brackish, fresh or sea water.
What is AFFF made of?
Synthetic foams Aqueous film forming foams (AFFF) are water-based and frequently contain hydrocarbon-based surfactant such as sodium alkyl sulfate, and fluorosurfactant, such as fluorotelomers, perfluorooctanoic acid (PFOA), or perfluorooctanesulfonic acid (PFOS).
Does all fire fighting foam contain PFAS?
Class A firefighting foams are used for wild fires and structural fires and do not contain PFAS chemicals. However, there are cases when AFFF is used because there may be a liquid fuel in the structure or wild fire region-such as gas stations, or oil cans.
Does all AFFF contain PFAS?
All AFFF products contain PFAS. This applies to foams used in the past and those being sold today. Foam currently in stock or new foam that is labeled as AFFF or AR-AFFF, contains perfluoroalkyl or polyfluoroalkyl substances, or both, as active ingredients (DOD 2018; Darwin 2004).
Is AFFF Class A or B?
The vast majority of Class B firefighting foam that is currently in stock or service in the United States is AFFF or AR-AFFF. All AFFF products contain PFAS. This applies to foams used in the past and those being sold today.
Is Class A foam a wetting agent?
Although class A foam contains wetting agents that reduce the surface tension of the contained water, it should not be confused with the wetting agents which are used exclusively for improving the penetration of water into deep-seated fires in class A fuels.
What is AFFF made from?
What kind of firefighting foam does Chubb use?
Chubb offers a comprehensive range of Angus Fire firefighting foam and BioCentral water enhancing products and services to help control and extinguish hydrocarbon and polar solvent fires. The new range of Angus Fire Integrity foams incorporate both fluorine free and fluorinated foams, which contain only pure C6 fluorosurfactants.
Where to store chemguard C3b 3% AFFF concentrate?
CHEMGUARD C3B 3% AFFF Concentrate should be stored in the original supplied package (HDPE totes, drums, or pails) or in the recommended foam system equipment as outlined in Tyco Fire Protection Products Technical Bulletin “Storage of Foam Concentrates”. The product should be maintained within the recommended temperature range.
What kind of water enhancer does Chubb use?
BLAZETAMER380™ water enhancer BLAZETAMER380™ from BioCentral Laboratories is proudly represented by Chubb. It represents the latest in water enhancer technology and has been tried and tested in various places around the world and has numerous approvals.
Are there any PFOS in chemguard 3% AFFF?
The environmentally-mindful CHEMGUARD C3B 3% AFFF Concentrate formulation contains short-chain, C-6 fluorochemicals manufactured using a telomer-based process. The telomer process produces no PFOS, and these C-6 materials do not breakdown to yield PFOA.
