T-STORM WTS31 3% AFFF (Aqueous Film-Forming Foam) Concentrate from Williams Fire & Hazard Control combines fluoro- and hydrocarbon-surfactant technologies to provide superior fire and vapor suppression for Class B hydrocarbon fuel fires.

Description

T-STORM WTS31 3% AFFF (Aqueous Film-Forming Foam) Concentrate from Williams Fire & Hazard Control combines fluoro- and hydrocarbon-surfactant technologies to provide superior fire and vapor suppression for Class B hydrocarbon fuel fires. This synthetic foam concentrate is intended for firefighting applications at 3% solution in fresh, salt, or hard water.

T-STORM WTS31-FP foam solution utilizes three suppression mechanisms for rapid fire knockdown and superior burnback resistance:

  • The foam blanket blocks oxygen supply to the fuel.
  • Liquid drains from the foam blanket and forms an aqueous film that suppresses fuel vapor and seals the fuel surface.
  • The water content of the foam solution produces a cooling effect for additional fire suppression.

The environmentally-mindful T-STORM WTS31-FP 3% FreezeProtected AFFF Concentrate formulation contains short-chain, C-6 fluorochemicals manufactured using a telomer-based process. The telomer process produces no PFOS, and these C-6 materials do not breakdown to yield PFOA. The fluorochemicals used in the concentrate meet the goals of the U.S. Environmental Protection Agency 2010/15 PFOA Stewardship Program and the current ECHA Directive (EU) 2017/1000.

Approvals, Listings, and Standards

T-STORM WTS31 3% AFFF Concentrate is designed in accordance with National Fire Protection Association (NFPA) Standard 11 for Low-, Medium-, and High-Expansion Foam. The concentrate is approved, listed, qualified under, or meets the requirements of the following specifications and standards:

  • UL Standard 162, Foam Liquid Concentrates
  • ULC S564, Category 2 Foam Liquid Concentrates

Application

T-STORM WTS31 3% AFFF Concentrate is intended for use on Class B hydrocarbon fuel fires with low water solubility, such as crude oils, gasolines, diesel fuels, and aviation fuels. It is not suitable for use on polar fuels with appreciable water solubility, such as methyl and ethyl alcohol, acetone, and methyl ethyl ketone. The concentrate also has excellent wetting properties that can effectively combat Class A fires.

To provide even greater fire protection capability, T-STORM WTS31 foam solution may be applied simultaneously with WILLIAMS FIRE & HAZARD CONTROL PKW dry chemical for a twin-agent system.

T-STORM WTS31 can be ideal for fixed, semi-fixed, and emergency response firefighting applications such as:

  • Fuel or chemical storage tanks
  • Industrial chemical and petroleum processing facilities
  • Truck/rail loading and unloading facilities
  • Flammable liquid containment areas
  • Aircraft hangars
  • Mobile equipmen

Foaming Properties

T-STORM WTS31-FP 3% Freeze-Protected AFFF Concentrate may be effectively applied using most conventional foam discharge equipment at a 3% dilution with fresh, salt, or hard water. For optimum performance, water hardness should notexceed 500 ppm expressed as calcium and magnesium.

T-STORM WTS31-FP Concentrate requires low energy to foam and the foam solution may be applied with aspirating and nonaspirating discharge devices. Non-aspirating devices, such as handline water fog/stream nozzles or standard sprinkler heads, typically produce expansion ratios from 2:1 to 4:1. Aspirating low-expansion discharge devices typically produce expansion ratios from 3.5:1 to 10:1, depending on the type of device and the flow rate. Medium-expansion discharge devices typically produce expansion ratios from 20:1 to 60:1.

Proportioning

The recommended operational temperature range for T-STORM WTS31-FP 3% Freeze-Protected AFFF Concentrate is -20 °F to 120 °F (-29 °C to 49 °C) per UL-162. However, the diluted solution will freeze at 32 °F (0 °C). This foam concentrate can be correctly proportioned using most conventional, properly calibrated, in-line proportioning equipment such as:

  • Balanced and in-line balanced pressure pump proportioners
  • Balanced pressure bladder tanks and ratio flow controllers
  • Around-the-pump type proportioners
  • Handline nozzles with fixed eductor/pick-up tubes

For immediate use: The concentrate may be diluted with fresh or sea water to a 3% pre-mix solution.
For delayed use: Consult Technical Services for guidance regarding suitability of a stored pre-mix solution (fresh water only).

Materials of Construction Compatibility

To help avoid corrosion, galvanized pipe and fittings should never be used in contact with undiluted T-STORM WTS31-FP 3% Freeze-Protected AFFF Concentrate. Refer to Johnson Controls Technical Bulletin “Acceptable Materials of Construction” for recommendations and guidance regarding compatibility of foam concentrate with common materials of construction in the firefighting foam industry.

Storage and Handling

T-STORM WTS31-FP 3% Freeze-Protected AFFF Concentrate should be stored in the original supplied package (HDPE totes, drums, or pails) or in the recommended foam system equipment as outlined in Johnson Controls Technical Bulletin “Storage of Foam Concentrates”. The product should be maintained within the recommended temperature range. If the concentrate freezes during transport or storage, full product serviceability can be restored upon thaw with gentle re-mixing.

Factors affecting foam concentrate’s long-term effectiveness include temperature exposure and cycling, storage container characteristics, air exposure, evaporation, dilution, and contamination.
The effective life of T-STORM WTS31-FP Concentrate can be maximized through optimal storage conditions and proper handling. T-STORM concentrates have demonstrated effective firefighting performance with contents stored in the original package under proper conditions for more than 10 years.

Mixing T-STORM WTS31-FP Concentrate with other foam concentrates for long-term storage is not recommended. Use in conjunction with comparable 3% AFFF products for immediate incident response.

Inspection

T-STORM WTS31-FP 3% Freeze-Protected AFFF Concentrate should be inspected periodically in accordance with NFPA 11, EN 13565-2 or other relevant standard. A representative concentrate sample should be sent to Johnson Controls Foam Analytical Services or other qualified laboratory for quality analysis per the applicable standard. An annual inspection and sample analysis is typically sufficient unless the product has been exposed to unusual conditions.

Quality Assurance

T-STORM WTS31-FP 3% Freeze-Protected AFFF Concentrate is subject to stringent quality controls throughout production, from incoming raw materials inspection to finished product testing
and is manufactured in an ISO 9001:2008 certified facility.
