OPERATION UNDER USUAL CONDITIONS

ASSEMBLY AND PREPARATION FOR USE

Construction of Berm

WARNING

Make certain that the berm gate valve is closed and locked after installing and

draining the berm. In the event of tank rupture, an open berm gate valve would

permit fuel to drain from the berm. Undetected fuel leakage can result in an

explosion and cause death, severe personal injury, and damage to equipment.

CAUTION

Damage to tank may occur if chosen site is not free of sharp objects (rocks,

sticks, glass, etc.), and center of leveled area should not exceed 9.0-inches

(22.86-centimeters) below ground level. Retain a slight incline for draining

surface water.

NOTE

A minimum of 5.0-foot (1.52-meter) working clearance is necessary between the side

of the tank and the berm on all four sides. When a single berm is used to contain

more than one tank, maintain a 5.0-foot (1.52-meter) space between tanks. The

installation site should have less than a 3.0 degree grade in order to prevent creeping

of the tank.

NOTE

If possible, provide a 4.0-inch (10.16-centimeters) thick sand bottom for all collapsible

fuel storage tanks. To provide a berm drain for all collapsible fuel storage tanks, place

a 2.0-inch (5.08-centimeter) pipe with a gate valve through the bottom of the

discharge end of the berm in order to provide a means of draining accumulated water.

Position the drain assembly at the lowest point of the slope to aid in draining water or

sludge. The gate valve should be normally closed, and opened only to drain water

from the bermed area. Install a cloth, if provided, in the bermed area for all collapsible

fuel storage tanks.

3,000-Gallon (11,360 liters) Tank

NOTE

The following instructions are for a 13.0-foot by 13.0-foot (3.962-meter by 3.962-

meter) tank in flat (empty) dimensions.

1. Clear and level an area 29.0-feet by 29.0-feet (8.84-meters by 8.84-meters).

2. Slope all four sides of leveled area in toward the center. The center should be no more than 3.0-inches

(7.62-centimeters) below ground level, equal to an approximate slope of 1.0 degree.

3. Erect a 3.5-foot (1.07-meter) high berm around the outside of the sloped area.
