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
  • Stable foam blanket provides burnback resistance and post-fire security
  • Foam blanket reseals when ruptured by personnel or equipment
  • Suitable for use with fresh or sea water

 

Performance Approvals

TridolC6 S3 meets the following International Standards:

  • Independently tested and certified to EN1568:2008 part 3.
  • Exceeds ICAO Level B fire performance and is certified to this performance level.
  • Audited and approved to Underwriters Laboratories UL162 (7th Edition).
  • Meets the requirements of IMO MSC.1/Circ.1312 .

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.

Equipment

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.

Compatibility

TridolC6 S3 is suitable for use in combination with:

  • Soft or hard, fresh, brackish or sea water.
  • Dry powder extinguishing agents either separately or as twin agent systems due to the C6 content.
  • Expanded protein-based or synthetic foams for application to a fire in sequence or simultaneously.

Storage

TridolC6 S3 is exceptionally stable in long-term storage. A shelf-life of at least ten years can be expected if it is stored properly.

Product Quality

TridolC6 S3 production is closely controlled and is audited by UL is accordance with their approval system.

Angus Fire operates a quality management system which complies with the requirements of BS EN ISO 9001.
