Where blasting materials are used, a manager must be appointed to be responsible for the control, management and direction of the work. The appointment must be made in writing, and the original letter of appointment, bearing the signature of the person making the
appointment, as well as the signature of the appointee, accepting the appointment, must be sent to the Chief Inspector of Explosives and a copy thereof must be retained by the appointee. Whenever the appointed
manager is necessarily away from his place of work owing to illness or for any other reasons whatsoever, he must ensure that a competent person is appointed, as aforesaid, to act as his deputy.
