Tridol C6 S3

3% Aqueous Film-Forming Foam (AFFF)

TridolC6 S3 is a superior quality synthetic Aqueous Film-Forming Foam (AFFF) concentrate for extinguishing and securing flammable hydrocarbon liquid fires.

TridolC6 S3 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 S3 is measured primarily against Underwriters Laboratories Standard UL 162 (7th edition).
  • Independently Tested and Certified to EN1568:2008 Part 3.
  • Performance exceeds ICAO Level B fire performance and is certified to this performance level.

Environmental Impact

TridolC6 S3 is biodegradable and demonstrates low toxicity to aquatic organisms.

Applications

TridolC6 S3 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 S3 provides a vapour suppressing foam blanket on unignited hydrocarbon spills. 

Proportioning

TridolC6 S3 is intended for use at 3% (3 part concentrate to 97 parts water). TridolC6 S3 is readily proportioned using conventional foam proportioning equipment.

TridolC6 S3 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 S3 is also suitable for base injection or sub surface 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.
