Visual Inspection Procedure
Tanks should be visually inspected every three to six months, depending upon frequency of use.
a.
Position tank on a clean, smooth surface, so that it is easily accessible on all sides.
b.
Inflate the tank to shape (approximately 1 PSI).
c.
Inspect hardware for damage and sharp edges. Sharp edges should be filed smooth to prevent damage to the
tank body. Damaged hardware should be replaced. (Paras. 3-6 and 3-7).
d.
Torque all bolts on clamp fittings. Use 70 ± 5 ft. lbs.
e.
Inspect tank body by rolling from side to side. Carefully inspect for cuts, tears, bruises, chafe markets, loose
edges, or any surface looseness.
f.
Whenever damage is discovered, even if it extends only through the external covering, repairs should be made at
once.

Emergency Repairs with Sealing Clamps
(1)
Small slits, tears or cuts (not to exceed 6* inches in length will be repaired with sealing clamps. (Fig. 3-1).

The size of the damaged tank area (opening) needing repair govern the size and applicability of the clamp
to effect a tank repair. The following criteria is furnished as guidance in selection of appropriate size clamp:
(a)
For holes (tears) up to 2 inches in length, install the 3 inch sealing clamp.
(b)
For holes (tears) 2 to 4 inches in length, install the 5 inch sealing clamp.
(c)
For holes (tears) 4 to 61 inches in length, install the 71 inch clamp.
(3)
It may be necessary to increase the size of the tears slightly with a pocket knife in order to be able to
insert the bottom plate of the sealing clamp.
(4)
Slip the bottom plate of the sealing clamp through the hole or tear and rotate it until it is centered and
parallel to the tear.
