Tridol C6 S6 LT
6% Low Temperature Aqueous Film-Forming Foam (AFFF-LT)
TridolC6 S6 LT is a superior quality synthetic Aqueous Film-Forming Foam (AFFF) concentrate for extinguishing and securing flammable hydrocarbon liquid fires.
TridolC6 S6 LT 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
- Suitable for use with fresh or sea water
Performance Approvals
- The fire performance of TridolC6 S6 LT is measured primarily against internal test procedures.
- Independently tested and certified to EN 1568: 2008 Part 3
Applications
TridolC6 S6 LT is used in high risk situations where hydrocarbons (such as crude oil, gasoline, diesel fuel, and aviation kerosene) are stored, processed, or transported. It is used extensively on Rapid Intervention Vehicles (RIV) at major international airports and military bases where fast extinguishment with limited quantities of foam is essential for saving life. Other applications include hydrocarbon storage tanks, process areas, warehouses, road/rail loading racks, power stations, marine terminals, and offshore platforms.
TridolC6 S6 LT provides a vapour suppressing foam blanket on unignited hydrocarbon spills.
TridolC6 S6 LT can also be used as a wetting agent in combating fires in Class A materials such as wood, paper, and tyres.
Equipment
TridolC6 S6 LT is intended for use at 6% (6 parts concentrate to 94 parts water).
TridolC6 S6 LT is readily proportioned using conventional foam proportioning equipment such as portable and fixed (in-line) foam venturi proportioners, handline nozzles/branchpipes with pick-up tubes, balanced pressure variable flow proportioners, balanced pressure bladder tank proportioners, and around-the-pump proportioners.
TridolC6 S6 LT can be used with air aspirating discharge devices such as low expansion branchpipes, monitors, top pourer sets, rimseal foam pourers, foam/water sprinklers, and base (sub-surface) injection systems.
TridolC6 S6 LT can be used with non-aspirating discharge devices such as spray/fog branchpipes and nozzles, monitors, and spray/fog sprinklers.However, non-aspirated application is not recommended as the primary method of attack for major fires where a stable foam cover is essential.

Compatibility
TridolC6 S6 LT 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.
- Expanded protein-based or synthetic foams for application to a fire in sequence.
Storage
TridolC6 S6 LT is exceptionally stable in long-term storage. A shelf-life of at least ten years can be expected if it is stored properly.
Reliability
TridolC6 S6 LT is produced to rigorous quality control standards to ensure consistent fire performance and excellent product reliability.
