The permit
Your hot work permit, built to your site.
Every check is configured to your site's procedures, limits and roles. Add, remove or reorder steps, then every permit follows it.
Gas test limits
Your site's limits, such as O₂ 19.5–23.5%, LEL ≤10%, CO ≤25 ppm and H₂S ≤10 ppm, recorded with the time and the tester.
Fire watch
A named watch, the duration your site sets after work ends, and sign-off at close.
PPE
The equipment your site requires for the job, listed on the permit the crew signs.
Linked isolations
A linked lockout plan is required before the permit can be authorized.
Approval roles
Who requests, authorizes, issues and closes, matched to your site's roles.
At the job
For the welder and the fire watch.
Contractor sign-on per permit
External welders sign on to the permit they work under, with their company recorded.
Fire watch countdown
The post-work timer notifies the watch, who records each check before the permit closes.
PDF matches your current form
File or print the permit in the layout your site already uses.
Hot work checks
Built around the checks your insurer and OSHA 1910.252 expect, tailored to your site.
Each check is a step on the permit, set up around your site's own hot work procedure, signed in order before work starts and kept on the record.
