Cold work is a permit classification used by some organisations. It should never be read as a promise that a job has little risk. A cold work permit checklist helps the issuer and work team define the task, check the local conditions and decide whether other authorisations are needed before work starts.
Before using the checklist
Start with the actual method, equipment and surroundings. A task without visible sparks can still involve stored pressure, electricity, chemical exposure, falling objects or traffic. Review the site definition of cold work and the proposed equipment. HSE describes permits as a formal way to communicate specified work and precautions. It does not prescribe one universal cold-work form or classification for every workplace.
Copy and adapt: Use this original checklist within your controlled site process. Add the applicable references and retain evidence for each decision.
Cold Work Permit Checklist
| Review item | What to confirm or record |
|---|---|
| Task boundary | Identify the equipment, work location, tools and limits of the authorised activity. |
| Classification | Check the site definition against the actual method; ask the permit authority about uncertainty. |
| Risk assessment | Confirm the relevant assessment and method statement match the task and current conditions. |
| Energy and contents | Identify pressure, electrical, mechanical and chemical hazards and the controlled isolation references where applicable. |
| Access and work area | Check safe access, lighting, housekeeping, barriers and escape arrangements. |
| Interfaces | Review nearby lifting, vehicle movements, hot work and other permits affecting the same area. |
| People and equipment | Confirm relevant competence, equipment suitability and pre-use checks. |
| Additional controls | Record any gas testing, environmental protection, specialist permit or supervision required by the assessment. |
A worked example
Illustrative example: a team plans to remove a bolted cover using hand tools. Calling it cold work does not answer whether the equipment contains pressure or hazardous residue. The supervisor identifies the equipment and intended opening, then seeks the required isolation and process information from authorised personnel. If a powered cutting method is proposed later, the permit classification and controls are reviewed before that change is used.
Follow-up and records
Record the authorisation, validity, conditions for suspension and close-out requirements using the company system. Brief the crew on the boundaries. If the tools, method or location change, stop and ask whether the existing permit remains applicable. Do not quietly add a new activity under a broad description.
Record the date, location or asset, findings, action owner, due or hold point and closure evidence. Use Yes / No / Not applicable only with a reason where needed. A blank or unexplained tick should not hide an unresolved concern.
Track outstanding actions in your daily safety officer report. Review recurring problems through your safety committee action log.
Common questions
Does no visible spark mean cold work?
No. Use the site classification and an assessment of the method, equipment and environment. Visible sparks alone do not define all ignition hazards.
Can a cold work permit replace an isolation?
No. Link the relevant controlled isolation process and confirm it has been completed by the authorised people.
