11.1 As the safety of the handling of explosives
is affected by the degree of security attained, consideration should
be given to all security measures necessary to prevent unauthorized
access to explosives, including appropriate checks that all packages
are received in good order and condition at all stages of the handling
operation. Explosives should neither be moved nor handled unless the
relevant permits have been issued and such tasks should be undertaken
in accordance with the conditions specified in the relevant permits.
