Williams Fire & Hazard Control
Announces Streamline of ThunderStorm® Foam Products
This bulletin serves as formal communication that Williams Fire & Hazard Control, now part of Tyco Fire Protection Products, is retiring AR-AFFF fire fighting foam ThunderStorm® F-601B effective immediately as part of product rationalization effort. Customers should purchase ThunderStorm® AR-AFFF FC-601A (FC-601A) as an alternative product. FC-601A has been tested to be compatible with F-601B.

The Ambush™ System is designed to provide effective “system based” full-surface AND seal fire protection for external floating roof storage tanks.
Effective full-surface fire protection may be delivered by an experienced response team deploying significant water and foam resources via large-volume (Big Gun) manned transportable fire monitors, which are staged some distance from a burning tank — offering “over the top” trajectory and safe attack distances. This projection of water/foam solution onto the surface of the tank from a ground position is referred to as a “Type 3 Application”.
As a seal protection option, traditional fixed foam systems (foam chambers, or foam pourers) are referred to as providing a “Type 2 Application” — delivering a “cascading application” of water/foam solution from unmanned systems affixed to the tank itself. This method of delivery commonly results in lower application volume targeting the seal area. This delivery proves inadequate to extinguish a full-surface fire scenario.
Delivered from outside the tank, consideration must be given to “fallout” of a Type 3 application — the water/foam solution that does not land inside the tank due to wind or general stream erosion from the ground assault. The benefit of a fixed system “Type 2 Application” is a potential increase in foam application density, ie gallons-per-minute required per square foot of storage tank surface area. Mounted to the rim of the tank, the Ambush™ configuration delivers a Type 3 Application toward the center of the tank for full surface protection, while simultaneously delivering lateral Type 2 application streams along the tank wall for seal fire protection. The elevated position of the Ambush™ system at the tank rim reduces / eliminates wind erosion and delivers a more forceful seal area application — reducing application times and using less water and foam concentrate than a strict “Type 3 Application”.
As a fixed system component, the Ambush™ provides a quicker response time and less man power than a portable large volume delivery approach. Also, as a fixed system the Ambush™ requires less flow rate due to lower recommended application densities (gpm per ft2 of surface area exposed). Finally, use of the system requires less specialized training and exposes less personnel to a hazardous situation.
The Ambush™ System is available in several different sizes. Each size functions similarly. The stream is broken into 4 components. The Left/Right discharge streams are equal to each other and deliver foam left/right of the unit against the tank wall. The upper stream discharges foam at a slight angle toward the center of the tank. The fourth stream discharges foam back against the tank’s shell and protects the area just below the unit with a small stream.
As the multiple foam streams projecting toward the center of the tank converge, they extinguish the fire in the center of the tank then build back toward the tank’s shell. At the same time, the left/right streams project foam around the circumference of the tank extinguishing any fire near the tank shell. As the tank shell fire is extinguished, this coverage begins to grow toward the center of the tank to meet the foam blanket being established by the upper stream. Soon after, the entire tank will have a full foam blanket.

Dual Agent Foam Chamber
Recent responses have led Williams Fire & Hazard Control to develop this new COMPLIANCE+ product for automated incipient response to Internal Floating Roof Tanks.
Gorilla - 500 Lb PKW Dry Chemical Vessel
This package offers 500 lbs of dry chemical to sustain both ground and monitor based attacks — perfect for rollover events, terminal response, or any other three-dimensional scenario.
Center Shot / Flex Nozzle
Williams' nozzle design is intended to maximize reach and foam application for various scenarios.
Fire field logistics are ranked nearly as high as equipment on hand and personnel available when facing industrial responses. Large fires require large volumes of water, which sometimes require multiple large diameter water supply hoses. The most convenient, reliable, and safest means of distributing large volumes of water over an entire facility is by constructing underground water delivery systems with above ground hydrant manifolds. These hydrant manifolds are then used in conjunction with large diameter water supply hose to supply the necessary water to pumps, fire nozzles, and foam proportioning equipment.
• By more efficiently supplying water, swivel hydrants could reduce the number of necessary hydrant locations by as much as 50% (depending on hydrant layout and size)
