40-LB. DEMOLITION CRATERING CHARGE
The 40-lb. demolition cratering charge is a metal
cylinder containing explosive.
A metal ring
(lifting/lowering loop) on the top of the container is
used to lower the charge into a hole.
If this ring is missing, classify it as a MAJOR defect.
Inspect the charge for heavy rust or any penetration
that might cause the explosive to absorb moisture.
These conditions are MAJOR defects.
