A cold work permit is a written permit for hazardous work or environments that do not have a source of ignition. A cold work permit is a formal document that details the work procedures and precautions required to work safely, and authorizes the work to take place.
As part of a permit to work system, a cold work permit’s primary purpose is to eliminate the risk associated with and ensure the safety of worker(s) in the workplace. It is a formal document that authorises that the job is ready to be completed safely. There are many circumstances when a cold work permit is required but some common situations include: chemical cleaning and the use of solvents, handling toxic chemicals and substances, painting activity, and scaffolding. Many jurisdictions around the world require a cold work permit, as part of a permit to work system, to meet health and safety standards.
A cold work permit contains precautions that need to be taken before the work is started. For example, stating that appropriate personal protective equipment (PPE) is worn before chemical cleaning. It then contains the authorization that the standards have been satisfied to start work and the specific time period it is valid for. Additionally, it often contains the procedure upon completion of the work. Ensuring that the worker and workplace is returned back to safety.
A cold work permit tends to be issued by a project manager or a supervisor. They authorise that the precautions and procedures have taken place and the job can be completed safely. Cold work permits are used in a wide variety of industries and tend to be focused around maintenance and construction tasks.
