Permit to work
The permit-to-work system is a method whereby safety procedures are specified in writing on a form issued to seafarers who are assigned with a task which may involve work of a hazardous nature. Permits should only be used for the more hazardous tasks and the system should not become over-complicated.
The form should describe the work to be carried out and the necessary safety precautions. All probable hazards should be considered, a predetermined safe procedure should be adopted and the appropriate precautions should be written down in a correct sequence. The permit should contain a carefully planned checklist to identify, control or eliminate hazards and should state the emergency procedure in the event of an accident.
A permit should be issued only by an officer with experience in the work operation. The officer should ensure that the checks have been properly carried out and, together with the person in charge, sign the permit only when satisfied that it is safe for the work to proceed. The master should countersign any such permits. Procedures for locking off at points of isolation and signing for, and the subsequent cancellation of, permits and "making live" should be covered
Permit-to-work form – An Example
Note: The responsible officer should indicate the sections applicable by marks in the left-hand spaces next to the headings, and by deleting any subheading not applicable. The officer should insert the appropriate details when the sections for other work or additional precautions are used. The person in charge of the work should mark each applicable right-hand space when completing each check.
