Tridol C6 S1

1% Aqueous Film-Forming Foam (AFFF)

Tridol^C6 S1 is a superior quality synthetic Aqueous Film-Forming Foam (AFFF) concentrate for extinguishing and securing flammable hydrocarbon liquid fires.

Tridol^C6 S1 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

Product details

Performance Approvals

TridolC6 S1 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 S1 is audited and approved to Underwriters Laboratories UL162 (7th Edition).

Applications

Tridol^C6 S1 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) 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.

Tridol^C6 S1 provides a vapour suppressing foam blanket on unignited hydrocarbon spills

Equipment

Tridol^C6 S1 is intended for use at 1% (1 part concentrate to 99 parts water).

Tridol^C6 S1 is readily proportioned using conventional foam proportioning equipment.

Tridol^C6 S1 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 S1 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.

Compatibility

Tridol^C6 S1 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

Tridol^C6 S1 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

Tridol^C6 S1 production is closely controlled and is audited by UL in accordance with their approval system.

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