This is an electric blasting cap.
Electric blasting caps must be
handled with extreme care. Do not
drop them or hit them.
First, inspect the markings on the
box containing the blasting cap. If
the markings are misleading as to
the strength of the cap, classify the
defect as MAJOR. If the markings
are unidentifiable as to the strength
of the cap, the defect is MINOR.
Next, remove the electric blasting
cap from the box and inspect it for
splits, cracks, or any other exposure
of the charge. Inspect for corrosion.
These are all CRITICAL defects.
