A single spark from a welder’s torch can burn down your building. It’s happened thousands of times.
OSHA cites hot work violations constantly. NFPA estimates that 18,000 fires per year are caused by welding, cutting, and grinding operations. The average loss? Over $50,000 per incident.
Most of these fires were preventable. The companies just didn’t have — or didn’t follow — a Hot Works Policy.
If your team does any welding, cutting, grinding, or high-heat work, you need a formal Hot Works Policy. Not someday. Now.
Here’s why it matters — and how to build one fast.

What Is a Hot Works Policy?
A Hot Works Policy is your written game plan for controlling fire risk during high-heat operations.
It covers:
- Who can perform hot work
- Where it can be done safely
- What safety controls must be in place
- How to get authorization through permits
- When fire watches are required
Hot work includes:
- Welding (all types)
- Cutting and torch operations
- Grinding that creates sparks
- Soldering and brazing
- Any work producing flames, sparks, or heat above 500°F
No exceptions. If it creates heat or sparks, it’s hot work.
Why You Can’t Skip This
Some business owners think, “We’ve been welding for years without a policy. We’re fine.”
Then a fire happens. Your welder gets burned. Someone gets hurt trying to escape. And everything changes.
The property damage is bad. The worker injuries are worse. The insurance costs follow you for years.
Here’s What a Fire Costs You
Direct Property Damage:
- Building repairs: $50,000–$500,000+
- Equipment replacement
- Inventory loss
- Business interruption
The Human Cost — Your Employees Pay First
Before your building burns, your people get hurt.
- Burns — Second and third-degree burns requiring surgery, skin grafts, months of recovery
- Smoke inhalation injuries — Lung damage that can be permanent
- Injuries during evacuation — Falls, crush injuries, panic-related trauma trying to escape
- Psychological trauma — PTSD from surviving a workplace fire
- Death — Hot work fires kill workers every year
Every one of these injuries hits your workers compensation insurance. Hard.
The Experience Mod Impact
One serious burn injury can destroy your insurance costs for years.
A worker suffers third-degree burns. Medical treatment costs $150,000. They’re out of work for 8 months.
That claim:
- Raises your experience modification rate immediately
- Stays on your record for 3 years minimum
- Increases your workers comp premiums 20-40% or more
- Follows you even if you switch carriers
If your current workers comp premium is $50,000/year, a bad experience mod from one fire-related injury could cost you an extra $20,000 per year. For three years. That’s $60,000 in additional premiums — on top of the medical costs insurance already paid.
And if multiple workers are injured? Your experience mod could spike 50% or higher. Some businesses never recover.
See our post on how your experience modification rate works and why preventing injuries is critical.
And that’s just the tip of the iceberg. The real hit comes from uninsured costs—often 2, 3, or even 4 times the claim itself.
So if your insured claim was $75,000 and your uninsured costs were 3.5× higher, that’s another $262,500 out of pocket. Aren’t you glad insurance covered the $75K? Use our Safety ROI Calculator to estimate the true cost for your business.
Examples of Uninsured Costs:
- Lost contracts while you’re shut down
- Overtime rebuilding operations
- Customer trust damage
- Employee morale hit
- Potential lawsuits
Regulatory Consequences
- OSHA fines up to $16,550 per violation
- Investigations
- Potential criminal charges for gross negligence
Insurance Impact
- Claim hits your loss history
- Premiums spike for 3+ years
- Some carriers drop you entirely
- Higher deductibles on renewal
One preventable fire can cost you six figures. Sometimes it costs you the business.
OSHA and NFPA Aren’t Optional
OSHA’s 29 CFR 1910.252 requires formal procedures for hot work operations.
NFPA 51B sets the industry standard for hot work safety.
Insurance carriers expect compliance with both. Without a documented Hot Works Policy, you’re exposed on every front:
- Regulatory
- Legal
- Financial
- Operational
What Your Hot Works Policy Must Include
Don’t overcomplicate it. Cover these eight elements:
1. Purpose and Scope
State clearly: this policy exists to protect employees from injury and prevent fires during all hot work operations.
Define who it applies to:
- Your employees
- Contractors
- Subcontractors
- Temporary workers
- Anyone performing hot work on your property
2. Definitions
Define key terms so there’s no confusion:
- Hot Work — Any operation producing heat, sparks, or flames
- Hot Work Permit — Written authorization required before starting
- Fire Watch — Designated person monitoring for fires during and after hot work
- Designated Hot Work Area — Pre-approved space with permanent fire safety features
- Authorized Operator — Trained personnel approved to perform hot work
3. Roles and Responsibilities
Assign accountability:
Hot Work Program Manager
- Oversees the entire program
- Approves permits
- Ensures training compliance
- Reviews incidents
Supervisors
- Inspect work areas before hot work begins
- Verify fire safety equipment is in place
- Ensure fire watches are posted
- Stop work if conditions become unsafe
Authorized Operators
- Complete required training
- Follow all safety procedures
- Use proper PPE
- Report hazards immediately
Fire Watches
- Monitor during all hot work
- Watch for 30-60 minutes after work stops
- Know how to use fire extinguishers
- Have authority to stop work
4. Hot Work Permit System
Every hot work operation needs a permit. No exceptions outside designated hot work areas.
The permit process:
- Worker requests authorization
- Supervisor inspects the area
- All fire hazards are removed or protected
- Fire watch is assigned
- Permit is signed and posted at work site
- Work proceeds under supervision
- Fire watch continues after work stops
Permits expire daily. New permit required each day.
5. Designated Hot Work Areas: Skip the Daily Permit
If your team does hot work regularly, designated hot work areas can save time while maintaining safety.
What Is a Designated Hot Work Area?
A designated area is a permanent space specifically designed and approved for hot work operations. Once established, daily permits aren’t required — but all other safety protocols still apply.
Requirements for Designation:
Your designated area must have:
- Non-combustible construction — Fire-resistant walls, floors, and ceilings
- Clear zone — Minimum 35-foot radius free of combustibles
- Permanent ventilation — Adequate airflow to remove fumes and gases
- Fixed fire protection — Sprinkler coverage or suppression systems
- Fire safety equipment — Extinguishers, blankets, and emergency tools are always accessible
- Posted signage — Clear identification as a hot work zone
The Benefits:
Designated areas eliminate the need for daily permit paperwork for routine operations. Your welders can work faster without compromising safety.
But understand this: designated areas don’t eliminate safety requirements. You still need:
- Trained, authorized operators only
- Proper PPE for every operation
- Fire watch when conditions warrant
- Area inspections before starting work
- Fire safety equipment in place and functional
Document the Designation:
Your Hot Works Policy should include:
- Map showing all designated areas
- Specific safety features of each location
- Maintenance requirements
- Re-certification schedule (annual minimum)
- Conditions that would revoke designation
If you’re doing hot work daily, designated areas make sense. If it’s occasional, stick with permits.
6. Fire Prevention Requirements
Before any hot work begins:
Clear the Area:
- Remove all combustible materials within 35 feet
- If you can’t move them, cover them with fire-resistant blankets
- Check for hidden combustibles (insulation, wall cavities, dust)
Protect Openings:
- Cover floor drains
- Seal wall penetrations
- Block ducts and conveyor openings
Fire Safety Equipment:
- Fire extinguisher (minimum 10-lb ABC rated) within reach
- Fire blankets available
- Water source accessible
- Emergency contact numbers posted
Atmospheric Monitoring:
- Test for flammable gases
- Ensure adequate ventilation
- Check oxygen levels in confined spaces
7. Training Requirements
Training isn’t optional. Every person involved in hot work must complete:
Initial Training Covers:
- Fire hazard recognition
- Proper equipment use
- Permit procedures
- Emergency response
- PPE requirements
Refresher Training:
- Annual minimum
- After any incident
- When procedures change
- When new equipment is introduced
Specialized Training:
- Confined space entry (if applicable)
- Elevated work platforms
- Specific equipment operation
Document everything. Keep records for 7 years minimum.
8. Documentation and Recordkeeping
Keep detailed records of:
- All issued permits
- Training completion certificates
- Equipment inspections
- Incident reports
- Policy updates
Why? OSHA inspections. Insurance audits. Legal protection.
Accurate records prove you followed procedures. That matters when something goes wrong.
Hot Works in High-Risk Areas
Some locations need extra precaution:
Confined Spaces
- Atmospheric testing required
- Continuous ventilation
- Entry permit in addition to hot work permit
- Attendant stationed outside
Elevated Work
- Fall protection required
- Spark deflection below work area
- Extended fire watch zone
Near Flammable Liquids
- Additional clearance distance
- Vapor monitoring
- Specialized fire suppression ready
Active Production Areas
- Shutdown procedures
- Lock out/tag out equipment
- Clear all personnel
Don’t guess on high-risk hot work. If you’re not sure, stop and reassess.
The Fire Watch: Your Last Line of Defense
Fire watch isn’t a suggestion. It’s a requirement.
Fire Watch Duration
- During all hot work operations
- 30 minutes minimum after work stops
- 60 minutes in high-risk areas
- Longer if materials are still smoldering
Fire Watch Duties
- Watch for fires constantly
- No other tasks during watch
- Test fire extinguishers before starting
- Know evacuation procedures
- Have authority to stop work immediately
Most hot work fires start after the work is “finished.” The fire watch catches them early.
Common Hot Works Policy Mistakes
Don’t make these errors:
Mistake #1: No Permit for “Quick Jobs”
“It’s just a 5-minute weld” causes fires. And injuries. Every hot-work operation requires a permit outside designated areas. The permit isn’t paperwork — it’s injury prevention.
Mistake #2: Inadequate Fire Watch
Someone doing other tasks while “watching” isn’t a fire watch. They need to do nothing else.
Mistake #3: Skipping Contractor Enforcement
Your policy applies to everyone working on your property. No exceptions.
Mistake #4: Old or Missing Permits
Expired permits are worthless. One permit per day, properly documented.
Mistake #5: No Training Documentation
“They know how to weld” isn’t training documentation. Formal training records are required.

The Bottom Line
Hot work fires are expensive. They’re also preventable.
But the real cost isn’t the building — it’s your people. Burns, smoke inhalation, evacuation injuries — these don’t just hurt your team. They devastate your workers comp costs for years through your experience modification rate.
A Hot Works Policy protects your people first, your property second, and your business third. It’s not optional — OSHA and NFPA both require it.
The question isn’t whether you need one. It’s how fast you can implement it.
With Smarter Risk, implementation takes minutes instead of months. For $500, you get a complete safety program that meets — or exceeds — all regulatory requirements.
One prevented injury pays for itself 100x over.
FAQs
What activities require a hot work permit?
Any operation that produces flames, sparks, or heat above 500°F requires a hot work permit. This includes all welding, cutting, grinding, brazing, and soldering operations — unless performed in a pre-approved designated hot work area.
How long must a fire watch remain after hot work stops?
Minimum 30 minutes after work stops. High-risk areas require 60 minutes or longer. The fire watch continues until the supervisor confirms no smoldering materials remain and the area is safe.
Do contractors need to follow our Hot Works Policy?
Yes. Anyone performing hot work on your property must follow your Hot Works Policy. This includes contractors, subcontractors, vendors, and temporary workers. No exceptions. Make them sign off on it too—yes, we include that in our forms library.
What’s the difference between a hot work permit and a confined space permit?
A hot work permit authorizes welding or cutting operations. A confined space permit authorizes entry into confined spaces. If you’re doing hot work in a confined space, you need both permits.
Can we skip the permit for designated hot work areas?
Yes. Designated hot work areas with permanent fire safety features (fire-resistant walls, dedicated ventilation, built-in suppression systems) don’t require daily permits. But operators still need authorization, and safety equipment must be in place.
What training is required for hot work operations?
All operators need initial hot-work safety training covering fire prevention, equipment use, permit procedures, and emergency response procedures. Annual refresher training is required. Fire watches need fire extinguisher training. Specialized operations (confined spaces, elevated work) require additional certification. This is all covered in our Hot Works and Welding Safety Course.
How often should we update our Hot Works Policy?
Review annually, at a minimum. Update immediately after any hot work incident, when equipment changes, or when regulations are updated. Keep employees informed of all changes.
What fire extinguisher rating is required for hot work?
Minimum 10A20BC-rated fire extinguisher within immediate reach of all hot work operations. Larger operations or high-risk work may require multiple extinguishers or specialized suppression equipment.
Who can serve as a fire watch?
Any trained employee can serve as a fire watch. They must complete fire watch training, know how to use fire extinguishers, understand evacuation procedures, and have the authority to stop work. The fire watch cannot perform any other duties while on watch.
What happens if we get caught without a Hot Works Policy?
OSHA can cite you up to $16,550 per violation for serious and other-than-serious violations, and $165,514 per violation for willful or repeated violations. If a fire occurs without proper procedures, you face much higher fines, potential criminal charges, insurance claim denials, and civil liability for damages. The regulatory penalty is the smallest cost.
