What is 3% foam used for?
These formulations are also available for use at 3% on both hydrocarbons and polar solvent fuels. Class A foams may be used as a firefighting agent or as a fire barrier. When used as a wetting agent, the concentrate lowers the surface tension of the water, allowing better penetration into deep seated fires.
What are the differences between foam foam solution and foam concentrate?
What is the difference between foam concentrate and foam solution? Foam concentrate is a liquid foaming agent as received from the manufacturer. Foam solution is water into which foam has been introduced in the proper proportion.
Which are the types of foam concentrate?
The foam concentrate covered in this standard shall be of the following types :
- Type 3—To be used with 97 percent water and 3 percent concentrates,
- Type 6—To be used with 94 percent water and 6 percent concentrates, and.
- Type 1—To be used with 99 percent water and 1 percent concentrate.
What does 3% AFFF mean?
CHEMGUARD C3B 3% AFFF (Aqueous Film-Forming Foam) Concentrate combines fluoro- and hydrocarbon-surfactant technologies to provide superior fire and vapor suppression for Class B hydrocarbon fuel fires. Liquid drains from the foam blanket and forms an aqueous film that suppresses fuel vapor and seals the fuel surface.
Does AFFF foam expire?
If kept in the original unopened and airtight Chemguard supplied container and stored within the temperature range of 35ºF – 120ºF (2ºC – 49ºC) a shelf life of between 20-25 years can be expected.
What is class B foam used for?
Class B firefighting foams are commercial surfactant solutions that have been (and continue to be) stored and used for fire suppression, fire training, and flammable vapor suppression at military installations and civilian facilities and airports, well as at petroleum refineries and bulk storage facilities, and …
What are the types foam and foam making equipment?
Some of the equipments manufactured by the Company are Water Monitors, Foam Monitors, Water Foam Monitors, Portable Monitors, Foam Equipments, Foam Proportioning Skid, DCP Units, Spray Nozzles, Revolving Heads and Jumbo Curtain Nozzles, Deluge Valves, Water Spray, Foam & DCP Systems, etc.
Is Fire Fighting Foam toxic?
Firefighting foam contains numerous toxic chemicals known as “forever chemicals.” These chemicals do not break down quickly and stay around for a long time. They are linked to a variety of chronic and disabling illnesses and conditions, especially cancers.
Is Fire Fighting Foam corrosive?
Ship decks have aqueous firefighting foam (AFFF) stations that are used for fire fighting. The foam is, however, corrosive and can make holes in the decks. Right beneath those holes tends to be important rooms or tanks. They certainly wouldn’t want something dripping onto a person or equipment.
What makes 3% fluoroprotein foam concentrate so effective?
CHEMGUARD CFP3B 3% Fluoroprotein Foam Concentrate combines hydrolyzed protein with fluorochemical surfactants, foam stabilizers (metal salts), bactericide, corrosion inhibitors, freeze point depressants and solvents to provide superior fire and vapor suppression for Class B hydrocarbon fuel fires.
What are the NFPA standards for fluoroprotein foam?
CHEMGUARD CFP3B 3% Fluoroprotein Concentrate is designed in accordance with National Fire Protection Association (NFPA) Standard 11 for Low-, Medium-, and High-Expansion Foam. The concentrate is approved, listed, qualified under, or meets the requirements of the following specifications and standards:
How does fluoroprotein foam help in fire suppression?
The foam blanket blocks oxygen supply to the fuel and suppresses fuel vapor. Protein based foam agents produce a foam blanket with very good heat stability and burn-back resistance. The water content of the foam solution produces a cooling effect for additional fire suppression.
What should the temperature be for 3% fluoroprotein?
Typical expansion ratios for foam chambers are in range of 5:1 to 7:1. The recommended operational temperature range for CHEMGUARD CFP3B 3% Fluoroprotein Concentrate is 20 °F to 120 °F (-6.7 °C to 49 °C) per UL-162.
