Why the post-work watch matters
A spark that lands in insulation or a wall cavity can smolder unseen long after the welder packs up. That is why OSHA and the fire code require the fire watch to stay at least 30 minutes after hot work ends, and why NFPA 51B, insurers, and many facility permits call for longer watches and additional monitoring afterward.
What’s included
- Monitoring for the full period your permit requires — 30 minutes, 1 hour, or longer
- Systematic sweeps of the work area and adjacent spaces, above and below
- Extended monitoring for high-risk sites like refineries, roofs, and older wood structures
- Written, timestamped sign-off for your permit file
- Coverage that lets your skilled trades leave on time instead of standing watch
Post-Work Monitoring FAQ
Can you only cover the post-work period?
Yes. Many crews keep their own watch during the work and bring us in for the post-work period, especially at the end of the day. Tell us when work ends and how long your permit requires.
