Tridol C6 S6

6% Aqueous Film-Forming Foam (AFFF)

TridolC6 S6 is a superior quality synthetic Aqueous Film-Forming Foam (AFFF) concentrate for extinguishing and securing flammable hydrocarbon liquid fires.

TridolC6 S6 is a unique combination of hydrocarbon and fluorochemical surface active agents. It produces a vapour-sealing aqueous film that spreads rapidly over the fuel surface to provide rapid control and extinguishment.

  • Film-forming for fast flame knockdown and extinguishment.
  • Burnback resistance and post-fire security.
  • Foam blanket reseals when ruptured by personnel or equipment.

Performance Approvals

  • TridolC6 S6 is independently tested and certified to EN1568:2008 part 3.
  • Performance exceeds ICAO Level B fire performance and is certified to this performance level.
  • TridolC6 S6 is audited and approved to Underwriters Laboratories UL162 (7th Edition).

Environmental Impact

TridolC6 S6 is biodegradable and demonstrates low toxicity to aquatic organisms.

Applications

TridolC6 S6 is used in high risk situations where hydrocarbons (such as crude oil, diesel, and aviation kerosene) are stored, processed, or transported. It is used extensively on Rapid Intervention Vehicles (RIV) where fast extinguishment with limited quantities of foam is essential for saving life.

Other applications include hydrocarbon storage tanks, process areas, warehouses, power stations and offshore platforms. TridolC6 S6 provides a vapour suppressing foam blanket on unignited hydrocarbon spills.

Proportioning

TridolC6 S6 is intended for use at 6% (6 parts concentrate to 94 parts water).

TridolC6 S6 is readily proportioned using conventional foam proportioning equipment. TridolC6 S6 can be used with air aspirating discharge devices and non-aspirating. Devices include low expansion branchpipes, monitors, top pourers, rimseal pourers, as well as water and foam sprinklers. TridolC6 S6 is also suitable for base injection or subsurface application systems.  

Non-aspirated foam is suitable for shallow fuel fires and spill fires. Where a major fuel fire is involved, we always recommend the use of aspirated foam where a stable foam blanket is essential.
