A Permit to Work System provides a formal and disciplined approach to assessing the risks of a job and specifying the precautions to be taken when performing hot work and/or working in a confined space.
The permit to work system:
-
specifies the work to be done and
-
the equipment to be used
-
specifies the precautions to be taken when performing the task
-
gives permission for work to start
-
advises others that work is being performed
-
provides a check to ensure that all safety considerations have been taken into account, including the validity of permits and certificates and compliance to policies and procedures
-
provides a checking mechanism that all work has been completed to satisfaction
