Storage Tank Protection

High Volume Foam Monitors

Design Considerations

Determining Water/Foam RequirmentsCalculating the area of a circle: r2 = ft2

FT2x *Application Rate = GPM Water/Foam Solution

GPM Water/Foam Sol. x % Concentrate = GPM Foam Concentrate.

GPM Foam Concentrate x Recommended Duration (NFPA 11) = Total Gallons of Concentrate required on scene

*Application Rate per Square Foot

NFPA 11 recommends a minimum 0.16 gpm/ft2application rate for Type III.

Although 0.16 is a minimum much of the industry uses it as a standard.

Williams Fire & Hazard Control recognizes as the tank diameter increases, increasing the application rate must be considered.

Williams Recommended Type III Application Rates For Hydrocarbon Storage Tanks

0 - 150 0.16 GPM/Ft2

151 - 200 0.18 GPM/Ft2

201 - 250 0.20 GPM/Ft2

251 - 300 0.22 GPM/Ft2

300 + 0.25 GPM/Ft2

Example calculation for a 150 Storage tank:

75 x 75 x 3.14 = 17,662.5 ft2

17,662.5 x .16 = 2,826 gallons per minute required flow

(2,826 GPM would practically be rounded up to 3,000 GPM)

3,000 GPM x .01% concentrate = 30.0 gallons concentrate per minute30.0 Gal/concentrate for 65 minutes = 1,950 total gallons concentrate required (minimum)

Add 100% for reserve inventory (if required)

Minimum Foam Application DurationsCombustible Liquids (flash point < 100 F) = 50 minutes

Flammable Liquids (flash point > 100 F) = 65 minutes

Crude Oils = 65 minutes

Alcohols = 65 minutes

Minimum Foam Concentrate InventoriesCalculation for minimum foam inventory is (where D = Tank Diameter):

Minimum Foam Inventory =

(D x D) x 0.785 x (Min Application Density) x (% Proportioning) x (Application Duration)

Example calculation for an 80 Diameter Tank in Crude Oil Service:

(80 x 80) x 0.785 x 0.16 x .03 x 65 1568 gallons

Add for 100% Reserve Inventory (if required) + 1568 gallons

Total Minimum Foam Inventory 3136 gallons

Monitor / Nozzle Packages

Product Detail:

Big Foot Trailer Mount 4,000 - 14,000 GPM

The Williams Big Foot Multi-Flow High-Volume Monitor is designed for the

extinguishment of massive petrochemical fires. The nozzle is constructed of all cor-

rosion resistant materials, such as anodized aluminum, stainless steel, and composite

plastics, and is capable of flows ranging from 4,000 - 14,000 GPM. The nozzle is

available with six separate stems in increments of 2,000 GPM each. The nozzle is

the self educting type, incorporating patented Hydro-Foam technology. Foam concentrate is supplied via remote jet ratio controllers, or

foam solution can be delivered from an independent proportioning system directly to the water inlets. The nozzle is constant flow, with straight

stream to full fog capabilities.

The trailer meets all applicable DOT regulations and is constructed of deep channel carbon steel. Ballast tanks are an integral part of the

trailer, providing stability and traction to counteract nozzle reaction forces. The internal water inlet manifold is constructed of 10 I.D. stainless

steel. Eight (8) ea., 5 storz (6 optional) inlet connections with caps are provided for water-foam solution supply. The full system capacity of

14,000 gpm requires a total of ten (10) 5 storz inlets. Each connection is protected from back flow using a six inch (6) full flow wafer check

valve. Two (2) ea., 4 inlets are provided (one each side) for foam concentrate supply. The tandem axle trailer has a gross vehicle weight rating

(GVWR) of 14,000 lbs. Mechanical/hydraulic surge brakes are activated via a heavy duty coupler terminating in a pintle hook connection. The

tongue is connected rigidly to the trailer using an A-frame arrangement for maximum stability. Non-skid designed upper decking. Stabilizing

jacks are provided at four points, providing maximum stability.

An operators panel is located aft of the nozzle. The elevated operating position provides a full view of fire ground operations. All controls

are manual gear operated and utilize state-of-the-art hydraulic systems to control vertical travel (+15 to +45), horizontal traverse (from 15

right/left of center), and nozzle fog/straight stream pattern.

Ambassador 1 x 6 Monitor/Nozzle

Advancing the Fire Fighters Ability with

Equipment and Knowledge.

Description:This Hybrid nozzle has the unique capability to perform as an automatic

pressure or fixed gallonage nozzle. During automatic operation the nozzle will

respond to varying flows to maintain a nearly constant tip pressure, thus maximiz-

ing effective range for a given discharge flow. Once the nozzle reaches the fixed

gallonage set point (1000-6000 GPM), it performs as a conventional fixed gallon-

age nozzle. This is desirable for foam proportioning operations on storage tank

fires or other hazards requiring specific application rates. This nozzle is capable of Hydro-Foam proportioning at rates up to 6000 GPM @

3% (3000 GPM @ 6%) using remote jet pump technology. The extensive Ambassador options list allows this nozzle to be Hydro-Chem

capable with PKW flow rates from 25 lbs/s to 100 lbs/s. The single 8 full flow stainless steel waterway construction provides minimum friction

loss, maximum efficiency, and years of trouble-free service. The standard tiller-bar control provides full monitor articulation of 360 rotation

and down to -15 and up to +75 vertical travel. Pattern control from straight stream to full fog is accomplished via a full wrap-around handle

attached to the outer sleeve.

Ranger3

Description:The Ranger, featuring Smart Nozzle Technology, was designed for

todays Industrial fire fighting and protection needs. Hazards involving flammable

liquids in storage and liquids under pressure have met their match with the New

Millennium Equipment from Williams Fire & Hazard Control, Inc.

The Ranger monitor/nozzle combination is capable of not only self-

educting foam concentrate, but can do so while maintaining a nearly constant

pressure (+/- 10%) and a constant foam percentage (1% or 3% selectable) regardless of the flow rate. Discharge flow rates from 1000-3000

USGPM (3800-11356 LPM) can be water only, Hydro-Foam (using jet pumps or automatic constant/selectable metering) or Hydro-Chem

for extinguishing liquids and gases under pressure. All this and the operator is still afforded the freedom of smooth, rapid horizontal and vertical

movement that only the Ranger can provide, raising this monitor/nozzle above all others.

This Hybrid nozzle has the unique capability to perform as an automatic pressure or fixed gallonage nozzle. During automatic

operation the nozzle will respond to varying flows to maintain a nearly constant tip pressure, thus maximizing effective range for a

given discharge flow. Once the nozzle reaches the fixed gallonage set point (1000-3000 GPM), it performs as a conventional fixed gal-

lonage nozzle. This is desirable for foam proportioning operations on storage tank fires or other hazards requiring specific application

rates. This nozzle is capable of Hydro-Foam proportioning at rates up to 3000 GPM @ 3%. It can automatically maintain a nearly

constant foam percentage (1% or 3%) throughout the entire flow range while self-educting. It can optionally be configured to pro-

portion foam from remote locations using jet pump technology (thus forfeiting the constant/selectable metering feature). The exten-

sive Ranger options list allows this nozzle to be Hydro-Chem capable (without Hydro-Foam capability) with PKW flow

rates from 25 lbs/s to 50 lbs/s. The single 6 full flow stainless steel waterway construction provides minimum friction loss, maximum

efficiency, and years of trouble-free service. The standard tiller-bar control provides full monitor articulation of 360 rotation and down to

-15 and up to +75 vertical travel. Pattern control from straight stream to full fog is accomplished via a full wrap-around handle attached to

the outer sleeve.
