5.  Construction is one of the most challenging tasks, and the entire
process of construction involves several steps. If you think
construction only involves consultation, surveying, planning,
designing, and reviewing for approvals, there is more to it.

6. What is Work Permit in Construction?
• A Work Permit is a written form or document
used to authorize the jobs that endanger workers to
the serious hazards. It recognises the work to be
done, the hazards involved, and the necessary
preparation and the precautions for the job.
• It is an agreement between the Issuer & receiver
that the work to be done will be carried out in
accordance with the provisions stated in the
permit.

7.  The Work Permit system was developed to provide safety
in the workplace by controlling potential hazards inherent
to the industry.
e.g In the construction industry, work must be done under controlled
conditions to ensure the safety of workers and facilities.
· PURPOSE OF PERMIT SYSTEM
• Communication tool for understanding nature of the job and Identify
related hazards.
• Safety checklist that ensures proper procedures, equipment and
precautions are in place.

8. • Minimize risks to personnel and equipment.
• Work permits are not simple permission to carryout work,
but they determine how the work can be carried out safely.

 Second for workers directly involved in the task
 Third for safety department

19. In the case of operational plant, the Company normally has its own
permit system. The Operation Manager of the affected section of the
plant or his designated representative shall be the permit issuer. In a

28. The safety watch must be knowledgeable in:

31.  The Permit to Work is designed to provide a safe system
of work that can be applied to works identified by virtue
of perceived risks.
 This shall be applied to the Contractor controlled
Construction activities on the Project.
 Permit requirements for activities other than those
mentioned in this procedure will be re-evaluated
especially for potentially hazardous activities where an
extra degree of work control is felt to be appropriate.

32.  Compliance is key to all operators in the
Construction Industry.
Finally, “Accidents Bring Tears
