Jobsite Fire Caused By Hot Work: Which Contractor Policy Responds First?

​Welding, torch cutting, roofing, grinding, and other hot work can ignite combustible materials long after the crew believes the area is safe. For contractors in Colorado Springs, CO, determining which policy responds first after a jobsite fire depends on what was damaged, who performed the work, and how the project’s insurance program was structured.

What Is Considered Hot Work?
Hot work generally includes operations that produce flame, heat, sparks, or hot debris capable of starting a fire.

Common examples include:

• Welding
• Brazing and soldering
• Torch-applied roofing
• Cutting metal with a torch
• Grinding
• Heat-gun use
• Thawing pipes with flame-producing equipment
• Certain asphalt and waterproofing operations

The fire may begin immediately, or sparks may smolder inside insulation, wall cavities, roofing materials, or debris before flames become visible. That delay can complicate both the investigation and the insurance claim.

There Is No Single Policy That Always Responds First
The first responding policy is determined by the type of loss rather than simply by the fact that a contractor caused the fire.

Several policies may become involved:

• Builder’s risk insurance for the construction project
• Commercial general liability for damage to third-party property
• Contractors equipment coverage for tools and machinery
• Workers compensation for injured employees
• Commercial auto for damage involving insured vehicles
• Umbrella or excess liability for claims above underlying limits

One fire can trigger multiple claims because different policies protect different property and parties.
In our work with clients, a common issue we see is contractors assuming that general liability automatically pays for everything damaged at a project. General liability and builder’s risk serve different purposes and may respond to separate portions of the same loss.

Builder’s Risk Often Handles Damage to the Project
Builder’s risk is generally designed to insure the structure under construction, installed work, and qualifying materials intended to become part of the project.

If hot work causes a fire that damages framing, roofing, installed mechanical systems, or materials awaiting installation, builder’s risk may be the primary source of property coverage.

Potentially covered property may include:

• The structure under construction
• Installed fixtures
• Building materials
• Materials stored at the jobsite
• Certain materials in transit
• Temporary construction components
• Debris removal after a covered fire

The builder’s risk insurer may pay for covered project damage and later seek reimbursement from the contractor or subcontractor believed to have caused the fire. This recovery process is called subrogation.

Whether subrogation is allowed may depend on waivers contained in the construction contract and policy.

When General Liability May Respond
Commercial general liability insurance may respond when the contractor’s hot work causes bodily injury or property damage to another party.

Examples include:

• Fire spreads to an adjacent building
• A customer’s existing property is damaged
• A neighboring tenant’s belongings are destroyed
• A visitor suffers burns or smoke inhalation
• The project owner seeks recovery for uninsured damage
• The builder’s risk insurer pursues the responsible contractor

General liability may help pay covered legal defense expenses, settlements, judgments, and property damage claims.

However, the policy may contain exclusions affecting damage to the contractor’s own work, property in its care, or specific operations. Coverage also depends on whether the contractor complied with policy conditions and accurately described its operations to the insurer.

Existing Structures Can Create Coverage Questions
Renovation projects are particularly complicated because the jobsite may include both new construction and an existing building.

Builder’s risk may cover the renovation work but provide limited or no coverage for the original structure unless existing building coverage was specifically included. If a subcontractor’s torch work damages both the new roof and the older building beneath it, more than one policy may be needed.

Possible coverage sources include:

• Builder’s risk for the renovation work
• The property owner’s building insurance
• The contractor’s general liability policy
• The subcontractor’s general liability policy

The construction contract should clarify which party insures the existing structure and whether it is included within the builder’s risk limit.

For renovation projects near Old Colorado City or the Broadmoor area, older construction materials, concealed cavities, and occupied spaces can increase both fire risk and claim complexity.

The Responsible Subcontractor’s Policy May Be Involved
When a subcontractor performs the hot work, its general liability policy may be the first liability policy examined. The general contractor may also be named in the claim because it controlled the jobsite, selected the subcontractor, or allegedly failed to enforce safety procedures.

The general contractor should verify that every hot-work subcontractor maintains:

• Commercial general liability
• Workers compensation
• Commercial auto when applicable
• Appropriate liability limits
• Completed operations coverage
• Required additional insured endorsements

Additional insured status may allow the general contractor to seek protection under the subcontractor’s liability policy for certain claims arising from the subcontractor’s work.

A certificate of insurance alone does not establish the full scope of coverage. The actual endorsement and policy terms control.

Workers Compensation Covers Injured Employees
If an employee is burned, suffers smoke inhalation, or is injured while responding to the fire, workers compensation is generally the relevant coverage for the employee’s work-related injury.

Benefits may include qualifying:

• Medical treatment
• Lost wages
• Rehabilitation
• Disability payments
• Death benefits

General liability usually excludes bodily injury to the contractor’s own employees when workers compensation applies.

If another contractor’s employee is injured, multiple insurers may investigate employment status, jobsite control, and whether any third party contributed to the injury.

Tools and Equipment Need Separate Protection
Builder’s risk may insure building materials but exclude reusable contractor tools and equipment. General liability does not usually pay for the contractor’s own burned equipment.

Contractors equipment or inland marine coverage may protect items such as:

• Welders
• Torches
• Generators
• Compressors
• Lifts
• Scaffolding
• Power tools
• Testing devices

Rented equipment may require separate coverage or specific contractual protection. Contractors should confirm whether rented, leased, and borrowed equipment is included and whether any sublimits apply.

How Waivers of Subrogation Affect the Claim
Construction contracts often include waivers of subrogation. These provisions may limit an insurer’s ability to pursue another project participant after paying a covered claim.

For example, a builder’s risk insurer may pay for fire damage to the project but be prevented from seeking reimbursement from a contractor if the owner and contractor agreed to waive subrogation rights for insured property losses.

The effect depends on:

• The contract wording
• The builder’s risk policy
• Which parties are protected
• Whether the loss falls within the waiver
• Whether gross negligence or another exception applies

Contractors should not assume that every waiver is enforceable or broad enough to prevent recovery. Contract language should be reviewed before work begins.

Hot-Work Exclusions and Policy Conditions
Some insurance policies impose specific conditions, limitations, or exclusions for hot work. Coverage problems may arise when a contractor performs operations that were not disclosed or fails to follow required safeguards.

The insurer may investigate whether the contractor used:

• A written hot-work permit
• A trained fire watch
• Fire extinguishers
• Combustible-material removal
• Protective curtains or blankets
• Post-work monitoring
• Proper ventilation
• Required separation distances

Failure to use precautions does not automatically eliminate coverage, but it can affect liability findings and may violate policy conditions or underwriting representations.

What Investigators Review After a Fire
After a significant jobsite fire, insurers may hire fire investigators, engineers, contractors, and legal counsel.

The investigation may examine:

• The fire’s point of origin
• Which contractor performed hot work
• Equipment used
• Work timing
• Weather and ventilation
• Safety procedures
• Permit records
• Fire-watch logs
• Photographs and surveillance footage
• Witness statements
• Contract and insurance requirements

Preserve documents and equipment immediately. Do not discard torches, extension cords, fuel containers, protective blankets, or damaged tools unless authorized.

Steps to Take After a Hot-Work Fire
Contractors in Colorado Springs, CO should:

1. Call emergency services.
2. Protect workers and the public.
3. Notify the project owner and general contractor.
4. Report the incident to applicable insurers.
5. Preserve the fire scene when safe.
6. Photograph damage and equipment.
7. Collect witness information.
8. Secure hot-work permits and fire-watch logs.
9. Gather contracts and insurance certificates.
10. Avoid admitting liability before the investigation is complete.

Notify every potentially relevant insurer promptly. Delayed reporting can make investigation more difficult and may affect coverage.

Preventing Hot-Work Claims
A formal hot-work program should include:

• Written permits
• Area inspection before work
• Removal or shielding of combustibles
• Proper extinguishing equipment
• Trained fire-watch personnel
• Continuous monitoring during work
• Post-work monitoring
• Clear subcontractor responsibilities
• Daily documentation
• Stop-work authority

Monitoring should continue after the operation ends because hidden materials can smolder before igniting.

Conclusion
After a hot-work fire, builder’s risk often responds first to covered damage involving the construction project, while general liability may address damage to other property, third-party injuries, or recovery claims against the responsible contractor. Workers compensation and equipment coverage may also apply, making coordinated policies, clear contracts, and documented safety procedures essential.
