Frequently Asked Questions
What is a hot work permit and why should I require one?▼
A hot work permit is a documented authorization system required by NFPA 51B for any welding, cutting, brazing, or grinding operation that produces sparks or heat. The permit requires a fire safety checklist (combustibles removed within 35 feet, fire extinguisher present, fire watch assigned), and must be signed before work begins. Property managers should maintain their own hot work permit program and require contractors to comply as a condition of working on the property.
How do I verify that a welder's insurance covers fire damage from hot work?▼
Request the declarations page and policy form from the welding contractor's GL carrier. Look specifically for any hot work exclusion, fire damage sublimit, or care-custody-and-control exclusion that might limit coverage for fire damage to your property. If the policy contains such exclusions, require the contractor to obtain an endorsement removing them before work begins.
What certifications should a welding contractor hold?▼
For structural welding, the contractor should hold AWS (American Welding Society) certification appropriate to the type of work: AWS D1.1 for structural steel, D1.2 for aluminum, or D1.6 for stainless steel. Individual welders should hold current AWS welder qualifications for the specific weld procedures being used. For pressure piping, ASME Section IX certification is required. These certifications are often referenced in insurance policies and can affect coverage.
What air quality measures should be taken for welding in occupied buildings?▼
Require local exhaust ventilation (fume extractors) at the point of welding, supplemented by general area ventilation. For welding on galvanized, stainless, or painted metals, additional protective measures are required due to zinc, chromium, and lead fume hazards. Coordinate with building management to adjust HVAC systems and notify occupants. The contractor's safety plan should address air monitoring and fume control measures.
Do welding contractors in Massachusetts need a license?▼
Licensing requirements for welding contractors vary by municipality in Massachusetts. Check with your local licensing board and always request proof of current licensure on the COI.
What happens if my welding contractors's insurance expires in Massachusetts?▼
In Massachusetts, you as the property manager could be held liable for injuries or damages caused by an uninsured welding contractors on your property. Massachusetts courts have consistently ruled that property owners have a duty to verify contractor insurance before allowing work to begin.
