Permit to Work System: Step-by-Step Guide

What is a work permit?

A work permit in safety is a formal document that specifies the type, scope, location, and duration of high-risk or non-routine activities that require special precautions to prevent accidents or injuries. A work permit also identifies the potential hazards involved in the activity and the measures to be taken to control them. It ensures that the necessary precautions are taken before, during, and after the work is done. A work permit is usually issued by a competent person who has assessed the risks and verified the safety conditions before, during, and after the work.

A work permit is signed by the person who authorizes the work and the person who performs the work to ensure that they understand and comply with the safety requirements. It is used to ensure that all necessary precautions are taken to minimize the risks associated with the work and to protect workers, the public, and the environment¹.

What is a Permit to Work System?

A permit-to-work system is a formal and documented procedure that is used to control and manage hazardous or potentially hazardous work activities and ensures that the work activities are carried out safely and efficiently. It is a way of communicating and controlling the risks associated with hazardous work, such as working at heights, confined spaces, hot work, electrical work, etc.

A Permit to Work System typically involves the following steps:

  • The work requester identifying the scope, location, duration, and hazards of the work
  • Assessing the risks and implementing the necessary control measures
  • The work authorizer reviews the work request and approves or rejects it based on the risk assessment and the availability of resources. Obtaining authorization from a competent person to proceed with the work
  • The work performer receives the permit to work and follows the instructions and precautions specified in it.
  • Displaying the permit at the work site and informing all relevant parties
  • The work supervisor monitors the work progress and ensures compliance with the permit to work conditions.
  • The work verifier inspects the work site and confirms that the work has been completed satisfactorily and that the site has been restored to a safe state.
  • Closing the permit when the work is completed or suspended and returned to the work authorizer.

A Permit to Work System helps to prevent accidents, injuries, and damages by ensuring that the work is planned, coordinated, and supervised properly. It also helps to comply with the legal and regulatory requirements for health and safety in the workplace.
