INSPECTION OF BOOSTER CANS

11. Inspect booster cans as follows:

(a) Inspect cans for leaks, holes, or any evidence that the TNT charge is wet.

(b) Examine the booster for deformations which might interfere with its movement inside the depth charge central tube. See that the joint between the can and head is tight and in good condition.

(c) Use a ring gauge with an inside diameter of 4.145 inches (plus 0.000, minus 0.003) and a length of 1.0 inch (plus or minus 0.030) to check the diameter of booster cans. The booster cans should pass freely through this gauge.

(d) Inspect the detonator envelope and see that it is in good condition and securely sol-dered in the booster can.

(e) if there is any indication that the booster is defective, set the unit aside for repairs or, if aboard ship, return it to a depot for replacement.
