Hot Work Permit System
Hot work permit system confirms whether welding, cutting, grinding and similar spark- or heat-generating activities are controlled through a formal permit procedure, as queried in property insurance proposal forms.

Typical proposal-form questions
- Is a formal hot work permit required before welding, cutting, grinding or similar activities are carried out, whether by own staff or contractors?
- Does the permit process require area inspection, removal of combustibles, fire watch and post-work monitoring for a defined period?
- Are contractors contractually required to follow the same hot work permit procedure as own staff?
Evidence
- Hot work permit procedure document
- Sample completed permits
- Contractor fire safety instructions / contract clauses
Why it matters for underwriting
Hot work such as welding, cutting and grinding is one of the leading causes of large commercial fire losses, precisely because it introduces an open ignition source into environments that otherwise have no naked flame, often carried out by contractors unfamiliar with the site’s specific hazards. A formal permit system forces a deliberate pause before work starts to check for nearby combustibles, arrange a fire watch and plan post-work monitoring, converting an inherently risky activity into a controlled one. Underwriters see the presence and consistent enforcement of such a system as a strong indicator of overall risk management discipline.
Capturing the attribute and evidence
Proposal forms ask whether a permit is required before any hot work, what the permit process covers (area clearance, fire watch, post-work checks), and whether contractors are bound by the same requirements as own staff. Underwriters typically request the written procedure itself, sample completed permits showing the process is actually used in practice, and contractual clauses obliging external contractors to comply, since informal or inconsistently applied systems provide little real protection.
Effect on coverage, premium and conditions
A robust, consistently enforced permit system, including for contractors, supports standard rating and can be cited favourably in risk engineering reports. A missing system, or one that exists on paper but is not consistently followed, commonly leads to a condition requiring implementation or enforcement, and losses arising from hot work carried out without a permit are frequently subject to policy exclusions or claims deductions where a warranty has been breached.
Mitigation measures
Where a permit system is missing or weakly enforced, insurers and risk engineers typically recommend introducing a written hot work permit procedure covering area inspection, removal or protection of combustibles, an assigned fire watch during and after work, a defined post-work monitoring period, and contractual obligations requiring contractors to follow the same procedure as own staff.
