4-10 50,000 Gallon Fabric Collapsible Tank Operation - Cont'd .
4-10.3 The tank T1CF is drawn down by suction from the operating transfer pump P1CF after opening the appropriate
valves, V3CF, V4CF, V8C, and V1 OCF.
4-10.4 The tanks can be drained through the drain connection D supplied with the tank.
4-10.5 It is important to note the following warnings and cautions in operating the 50,000 gallon fabric collapsible tanks.
WARNING
OVERFILL OF FABRIC COLLAPSIBLE TANKS
The fabric collapsible tanks are designed primarily for static liquid head pressure only. The
tank vents are set at 0.10 psig and are incapable of passing large volumes of liquid.
Overfilling will result in a spill through the vent and can, if filling under pressure, result in
overpressure and a tank rupture, causing a major and dangerous spill.
WARNING
CLEAR TANK VENTS
Prior to filling tank, inspect and make sure tank vents are always clear and clean. A plugged
tank vent can cause damage to the fabric tank or cause a loss of pump suction. Make sure
pressure relief feature is operating.
CAUTION
DAMAGED FABRIC TANKS
Prior to filling tanks, inspect for fabric flaws or breaks. Damaged fabric tanks must be
removed from service and repaired or replaced promptly. Failure to do so can result in a
major spill.
CAUTION
TANK DRAIN
Prior to filling tank, make sure the bottom drain valve is closed.
CAUTION
BERM DRAIN
Prior to filling tank, make sure the berm drain valve (if any) is closed.
CAUTION
TANK BERMS
Tank berms must be kept in good repair. The integrity of the berms is necessary to contain a
tank spill and isolate the resultant fire hazard to a single, relatively small area.
