Initial Inspection
When the equipment is received, all items should be carefully
checked against the bill of lading to be sure all crates and cartons
have been received. Examine units for shipping damage, removing
the units from the packaging if necessary. Units in question
should also be internally inspected. If any damage is noted, the
carrier should make the proper notation on the delivery receipt,
acknowledging the damage.
