What are the precautions to be taken before issuance of a general work permit?
Prior to issuing any work permit in industries, risk assessment is performed which involves identifying potential hazards, evaluating their severity, and implementing appropriate control measures to mitigate risks.
By addressing these hazards proactively, accidents can be prevented and protect workers from harm. Another key element of a work permit is ensuring effective communication among all departments involved and tools box to be given by the permit issuer and acceptor to the workers who are deployed to perform the job.
Clear instructions should be provided about the specific tasks being carried out, relevant safety procedures, and required personal protective equipment (PPE), all working together towards maintaining a safe working environment.
What is the cold work permit procedure?
Here are the steps for issuing general work permits in industries.
Step 1 : First, the permit issuer will analyze the job and perform the job preparation such as line isolation, and equipment preparation i.e. purging, venting, flushing, etc.
Step 2 : Next is to prepare the permit according to the job and hand it over to the service department. The service department will verify the permit with the job, do a signature to accept the job, notify the technician for the job, and give the toolbox talk.
Step 3 : The technician, taking the permit reaches the job location where the area operator will verify the job, permit, and job preparation and do the signature to approve the permit.
Step 4 : Then the technicians are allowed to perform the maintenance job. After completion of the job, the job acceptor will verify the completion of the job, notify the area operator, and after verification by the area operator inform to permit issuer.
Step 5 : After job completion and verification, permit closer procedure is followed, and the service department hands over the completed job to the process department (permit issuer).
