SCOPE / This procedure explains the proper operation of a firefighting foam tote station.
HEALTH
Special PPE & Special Hazards / Normal personal protective equipment (PPE), full firefighting gear for operations inside the fire control or hot zone.
SAFETY / Care must be taken. Fire water system is pressurized. (Above 125 psi). Nozzle fouling can cause unwanted water flow into the foam concentrate tote.
REFERENCE
DOCUMENTS / SAF 015, SAF 018, SAF 019, SAF 048
MSDS for Annul 1% freeze protected foam
Task Force Tips manual for Midforce nozzles
SPECIAL MATERIALS & EQUIPMENT / Ansul Foam concentrate
TFT Midforce Nozzles
QUALITY / Hydrant or station monitor must be completely open and firewater system pressure above 125 psi to assure maximum flow and performance.
ENVIRONMENTAL / Fire fighting foam is an alkaline surfactant, Notify the WWTU when used.

OVERVIEW

The Firefighting Foam Tote Station (FFTS) was designed as a quick attack fire extinguishing platform. The FFTS will provide foam to a Master Stream as well as a hand held hose line. The FFTS is intended for use by shift asset personnel in the immediate vicinity of an uncontrolled fire. Foam master stream operations may be initiated by asset employees in the area of the fire. The FFTS is easy to operate and extremely efficient. It is designed to operate from the refinery fire water pressure. Requiring only 125 PSI operating water pressure the FFTS hold 265 gallon storage of fire fighting foam concentrate the foam station is capable of supplying finished foam for over 15 min @ 1500gpm. or over 3 hours at 100gpm.

The station comes equipped with an automatic self educting 1500 gpm nozzle. The nozzle will adjust its flow automatically to produce the best possible fire stream. In addition there is a 100 foot hand held hose line provided that can supply 90 gpm of foam for use on smaller spills and fires.

Procedure No. SAF 073 Rev. No. 0

1.0 Activations / __1.1 Verify all outlet valves are closed.
CAUTION
Always completely open the hydrant valves. Failure to do so will restrict water flow and cause hydrant leaks from its drain holes.
__1.2 OPEN hydrant or P.I.V. valve. Using special wrench or hand wheel, turn oprerating nut counter-clockwise until it will no longer turn freely. This usually takes about 15-20 revolutions to accomplish.
__1.3 OPEN the monitor nozzle valve and position it towards the desired target.
__1.4 Remove cover from FFTS.
__1.5 OPEN quarter turn plug valve (A) on bottom of tote. This will fill the foam concentrate manifold.
WARNING
Fouling of the nozzle can cause reverse flow of water through the foam concentrate hose. Causing overfilling of the foam tote that result in contaimination of the concentrate or spillage through the tote vent.
2.0 Foam Operations – MONITOR / __2.1 Assure foam concentrate pick-up hose is connected to the nozzle.
__2.2 OPEN ball valve (B) on the concentrate manifold, foam concentrate should be flowing through the pick-up hose and finish foam flowing out of the nozzle.
__2.3 Apply foam by banking the stream off of structures, bounding off the ground or raining down onto the fire using a side to side motion.
CAUTION
Excess water will destroy finished foam. Be sure that other water streams are not impacting the area being foamed.
3.0 Foam Operations- HANDLINE / __3.1 Remove all 100’ of hose from the hose bin, and then OPEN the hydrant outlet valve supplying the RED hose attached to the hose bin inlet pipe.
__3.2 OPEN ball valve on the inlet of hose bin
__3.3 OPEN ball valve (C) on the concentrate manifold, OPEN firefighting nozzle slowly. Foam concentrate should be flowing through the pick-up hose. and finish foam flowing out of the nozzle in approximately 5 seconds.
__3.4 Apply foam by banking the stream off of structures, bouncing off the ground, or raining down onto the fire using a side to side motion.
4.0 Water Operations-HANDLINE / __4.1 See step 3.1 and 3.2
__4.2 Rotate eductor bypass selector valve to the WATER position by disengaging the silver lock button and rotating ¾ “to the water position.
__4.3 Open firefighting nozzle.
5.0 Decommissioning / __5.1 CLOSE main foam concentrate valves (A,B,C)
__5.2 CLOSE hydrant or station monitor main valve and disconnect RED supply hose from outlet valve and hose bin inlet. Remove firefighting nozzle.
__5.3 DRAIN (yellow) hose line by walking hose from the male end back to the FFTS. Load hose into the bin accordion style and attach nozzle.
__5.4 DRAIN the Foam concentrate line by disconnecting the pick-up hose from the monitor nozzle and opening (B) valve on the foam concentrate manifold.
NOTE: NOTE: Refill or top off foam tote with Ansul 1% freeze protected foam concentrate. See Safety Team for foam and loading instructions.
__5.5 Once drained reconnect Pick-up hose to the monitor nozzle and close (B) valve. Attach RED water supply hose to the inlet of the hose line eductor close hose bin inlet valve and put on the station cover.
__5.6 Winterize hydrant in cold weather, per SAF048.
