Description
Fomtec Enviro USP can be used at 2% with fresh water for low, medium and high expansion discharge devices. For sprinkler systems it should be used in 3% proportioning. For use on class A type fires induction ratio of 0.5-1% is recommended depending on application and discharge device. Fomtec Enviro USP can be used with sea water when used as a 6% mixture. For polar solvents it recommended to use between 6% to 9% depending on fuel type and water quality.
Application
Fomtec Enviro USP is intended for use on class B hydrocarbon fuel fires such as oil, diesel and aviation fuels as well as class A fires such as wood, paper, textiles etc.
Fomtec Enviro USP is especially suited whenever a fluorine-free alternative (PFAS) with high fire performance is required. Approved for use in sprinkler systems as per UL listing. Suitable for mobile firefighting by use of aspirating foam discharge devices such as foam branchpipes and monitors, where appli- cation rates and technique can be adjusted to the specifics
of each incident. Or in systems designed for use with the product based on recommended minimum applications rates, application duration and discharge devices.

Fire performance & Foaming
The fire performance of this product has been measured and documented according to “International Approvals” stated in this document. The design parameters depend on type of system and application. The use of the product should follow design guidelines. The foaming properties are depending on equipment used and other variables such as water and ambient temperatures. Average expansion 7:1, average ¼ drainage time 25:00 minutes using UNI 86 test nozzle.
Equipment
Fomtec Enviro USP can easily be proportioned at the correct dilution using conventional proportioning equipment.
The equipment should be designed to the foam type. Fomtec Enviro USP should be used with approved sprinklers or aspirating foam discharge devices giving an expansion of more than 7:1 for optimal performance.
Sprinkler application
Sprinkler applications are especially challenging for any foam due to the very low operating pressure and the very low expansion reached. Applying foam through a sprinkler is a very forceful application method and requires foam that can handle direct application and partial submersion into the fuel without losing its fire performance and burnback resistance. Foams that shall be regarded as suitable for Sprinkler applica-tions shall also be able to withstand limited time of water deluge directly onto the foam blanket without losing its burnback properties. Fomtec Enviro USP has passed these tests showing superior extinguishing and burnback properties. Refer to the FM Approval Guide and UL Listing for acceptable system con-figurations used with this concentrate and specific sprinkler SINs and their associated minimum application rates.
Compatability
Fomtec Enviro USP can be used together with foam compatible powders and other expanded foams. It is only intended for use with fresh water.
Fomtec Enviro USP concentrate should not be mixed with other foam concentrates.
For material compatibility please refer to Fomtec Technical Advices FTA 20 addressing the topic.
Tested to Boeing Specification Support Standard BSS7432 with conformity on all test parameters.
Environmental
Fomtec Enviro USP is formulated using raw materials specially selected for their fire performance and their environmental profile. The product is totally free from fluorinated surfactants and polymers and other organohalogens, and therefore it does not contain any PFAS. Fomtec Enviro USP is 100% biodegrad-able. The handling of spills of concentrate or foam solutions should however be undertaken according to local regulations. Normally sewage systems can dispose foam solution based on this type of foam concentrate, but local sewage operators should be consulted.
Full details will be found in the Material Safety Datasheet
(MSDS). For more detailed information please consult Fomtec Technical Advices FTA 40.
Storage/Shelf life
Stored in original unbroken packaging the product will have a long shelf life. Shelf life in excess of 10 years will be found in temperate climates. As with all foams, shelf life will be depen-dent on storage temperatures and conditions.
For storage recommendations and material compatibility please refer to our Fomtec Technical Advices FTA 10 addressing the topic.
Inspection/Testing/Maintenance
The foam concentrate should be tested annually. The testing should be made by a suitable laboratory for analysis of foam concentrates and should measure: pH, specific gravity, expansion, drainage time. Storage containers should be inspected and reevaluated for the suitability of the storage location in regard to temperature fluctuations (temperature should be as stable as possible). Exposure to direct sunlight should be avoided.
