Construction Site Fires and Explosions in NYC: What Injured Workers Should Know

On a crowded New York City project, a small ignition source can become a major emergency in seconds. Workers may suffer severe burns, smoke inhalation, lung damage, traumatic injuries, or falls while trying to escape.

Hill & Moin LLP represents construction workers injured throughout New York City. After a construction fire or explosion, determining where the fire started, what safety precautions were in place, and which companies were responsible for controlling the hazard can be critical to protecting an injured worker’s rights.

What Causes Construction Site Fires and Explosions in NYC?

Construction projects create constantly changing conditions.

A floor may be used for welding one day and electrical work the next. Temporary power may run through unfinished areas. Combustible materials may be stored near active work. Fire suppression systems may not yet be fully operational.

Common causes of construction fires and explosions include:

• Welding and cutting
• Grinding and other spark-producing work
• Defective electrical wiring
• Temporary electrical systems
• Overloaded circuits
• Propane and fuel leaks
• Gas-line damage
• Improperly stored flammable liquids
• Combustible construction debris
• Temporary heaters
• Chemical reactions
• Battery fires
• Explosive dust
• Smoking or open flames near hazardous materials

OSHA requires employers to develop and maintain an effective fire-protection and prevention program throughout construction, repair, alteration, and demolition work. Required fire-protection and suppression equipment must also be available at the jobsite.

Why Is Hot Work a Major Fire Hazard?

Hot work includes activities capable of creating flames, heat, sparks, or slag.

Welding and cutting are among the most common examples.

A welding spark can travel beyond the immediate work area and ignite materials that workers may not realize are vulnerable.

Federal construction regulations require movable fire hazards near welding, cutting, or heating operations to be moved to a safe location or otherwise protected when practical. If hazards cannot be removed, precautions must be taken to contain heat, sparks, and slag. OSHA also prohibits certain welding, cutting, and heating operations where flammable compounds or heavy dust concentrations create a hazard.

Materials that may ignite include:

• Wood framing
• Insulation
• Roofing materials
• Plastic sheeting
• Paint
• Solvents
• Adhesives
• Construction debris
• Fuel
• Gas cylinders

A worker performing hot work may be only a few feet from the ignition point, but fire can spread to other floors, wall cavities, shafts, or enclosed areas before workers realize what is happening.

What Other Fire Hazards Are Common on Construction Sites?

Not every construction fire begins with welding.

Electrical equipment is another significant concern. OSHA’s construction fire-prevention standard requires electrical wiring and equipment used for light, heat, or power to comply with applicable construction electrical requirements. It also requires internal-combustion exhaust systems to be located away from combustible materials.

Potential hazards include:

• Frayed extension cords
• Damaged electrical panels
• Improvised wiring
• Overloaded outlets
• Faulty temporary lighting
• Battery charging areas
• Generator exhaust
• Fuel storage
• Gas-powered heaters

Construction sites also frequently contain combustible packaging, lumber, drywall materials, trash, and temporary plastic barriers.

Good housekeeping is therefore part of fire prevention, not merely site appearance.

What Can Cause an Explosion?

Explosions may occur when a combustible gas, vapor, dust, or other material ignites rapidly.

Possible sources include:

• Natural gas leaks
• Propane leaks
• Acetylene
• Gasoline vapors
• Solvents
• Chemical vapors
• Combustible dust
• Pressurized containers
• Gas cylinders

Some explosions occur during renovation or demolition when workers encounter an unexpected gas line, tank, or hazardous material.

Others may happen because a flammable atmosphere develops in an enclosed space.

OSHA recognizes combustible dust as capable of creating fire and explosion hazards under certain conditions and has published guidance on reducing those risks.

Hazard	Possible Ignition Source	Potential Consequence
Natural gas leak	Electrical spark	Explosion and burns
Flammable solvent	Welding spark	Flash fire
Combustible debris	Hot slag	Spreading structural fire
Defective wiring	Electrical fault	Fire or shock
Propane cylinder	Open flame	Fire or explosion
Combustible dust	Spark or heat	Rapid explosion

Understanding the ignition source is often only the beginning of the investigation.

Why Are Construction Fires Especially Dangerous in High-Rise Buildings?

New York City construction frequently takes place in high-rise buildings.

Workers may be hundreds of feet above street level when an emergency occurs.

During construction, permanent fire doors, sprinkler systems, elevators, alarms, or stairway protections may not yet be fully operational. Temporary walls and materials can also change normal evacuation paths.

Smoke may travel rapidly through:

• Stairwells
• Elevator shafts
• Mechanical shafts
• Floor openings
• Ductwork
• Unfinished wall cavities

Workers on upper floors may have limited options for escape.

That makes planning, emergency communication, and keeping access routes clear particularly important.

You deserve a law firm that prioritizes your safety and recovery. If you were burned or otherwise injured in an NYC construction fire or explosion, Hill & Moin LLP can investigate how the incident started and whether required safety precautions were followed.

What Injuries Can Construction Fires Cause?

Burn injuries can be physically and emotionally devastating.

Depending on the temperature, duration, and type of exposure, a worker may suffer:

• First-degree burns
• Second-degree burns
• Third-degree burns
• Electrical burns
• Chemical burns
• Respiratory burns
• Smoke inhalation
• Carbon monoxide exposure
• Lung damage
• Eye injuries
• Scarring
• Nerve damage

Serious burns may require:

• Skin grafts
• Reconstructive surgery
• Infection treatment
• Physical therapy
• Occupational therapy
• Pain management
• Long-term wound care

Some workers may never regain the same mobility, sensation, or physical capacity they had before the accident.

Can Smoke Inhalation Be Serious Even Without Visible Burns?

Yes.

A worker does not need visible burns to suffer a significant fire-related injury.

Smoke may contain carbon monoxide, chemicals, soot, and other harmful substances. Inhaling hot gases can also damage the mouth, throat, and lungs.

Possible symptoms include:

• Coughing
• Wheezing
• Shortness of breath
• Chest pain
• Headache
• Confusion
• Dizziness
• Nausea
• Hoarseness

Anyone who experiences breathing problems after a construction fire should seek appropriate medical attention.

Symptoms can sometimes worsen after the initial incident.

Can Workers Be Injured While Escaping a Fire?

Yes.

Construction fire injuries frequently involve more than burns.

A worker may fall from a ladder, scaffold, temporary stairway, or elevated platform while trying to escape.

Workers may also be struck by falling material or injured in a crowd moving toward an exit.

An explosion can create its own impact injuries by throwing workers against walls, equipment, or the ground.

Possible secondary injuries include:

• Broken bones
• Traumatic brain injuries
• Spinal injuries
• Crush injuries
• Lacerations
• Internal injuries

These secondary injuries should be documented just as carefully as the burns themselves.

Who May Be Responsible for a Construction Site Fire?

Large NYC construction projects often involve many entities.

Potentially responsible parties may include:

• Property owners
• General contractors
• Construction managers
• Welding contractors
• Electrical contractors
• Plumbing or gas contractors
• Demolition contractors
• Material suppliers
• Equipment manufacturers
• Equipment rental companies

Responsibility will depend on how the fire started and which company had control over the relevant work or condition.

Imagine that welding is being performed near combustible insulation.

The welding subcontractor may be involved, but an investigation could also examine whether the general contractor maintained appropriate fire-safety procedures, whether combustible materials should have been removed, and whether suitable suppression equipment was available.

Can New York Labor Law Apply to a Fire or Explosion?

Potentially.

New York Labor Law Section 241(6) can impose a nondelegable duty on covered owners and contractors to provide reasonable and adequate protection during construction, excavation, and demolition work. A successful Section 241(6) claim generally requires a violation of an applicable, sufficiently specific Industrial Code regulation that contributed to the injury. New York courts continued to apply that framework in 2026.

Depending on the accident, regulations involving combustion devices, electrical equipment, welding, hazardous materials, or other safety conditions may become relevant.

For example, a 2026 New York appellate decision discussed an Industrial Code rule governing temporary combustion devices near combustible surfaces in the context of a Labor Law Section 241(6) claim.

Labor Law Section 200 may also be relevant in cases involving unsafe workplace conditions or methods, depending on control, notice, and how the accident occurred. New York courts describe Section 200 as a codification of the common-law duty to provide workers with a reasonably safe workplace.

What If a Fire Was Caused by Welding or Cutting?

Hot-work accidents should be investigated carefully.

Important questions include:

• Were combustible materials removed?
• Was the work area properly protected?
• Was suitable fire-extinguishing equipment immediately available?
• Were workers trained regarding fire hazards?
• Were flammable compounds present?
• Was the area inspected before hot work began?
• Did sparks travel through floor or wall openings?

OSHA requires suitable fire-extinguishing equipment to be immediately available during covered welding, cutting, and heating operations.

A fire that appears to have been caused by “one spark” may actually involve several preventable safety failures.

Don’t wait—your future starts with one phone call. Hill & Moin can examine the worksite, contractor responsibilities, safety procedures, and evidence surrounding the fire before conditions change.

What Evidence Is Important After a Fire or Explosion?

Fire scenes change quickly.

Emergency crews may remove debris, utilities may be shut off, damaged equipment may be discarded, and reconstruction may begin.

Important evidence can include:

• Photographs
• Surveillance footage
• Fire department records
• Incident reports
• Witness statements
• Hot-work permits
• Fire-watch records
• Safety plans
• Construction contracts
• Electrical inspection records
• Equipment maintenance records
• Gas-line records
• Material Safety Data Sheets or safety data sheets
• OSHA documentation
• Medical records

Equipment involved in the fire may also need to be preserved for inspection.

What Should You Do After a Construction Fire or Explosion?

Your immediate priority should be medical care and personal safety.

When circumstances allow:

1. Seek emergency medical attention.
2. Report the injury to your employer.
3. Describe all symptoms, including breathing problems.
4. Identify witnesses.
5. Preserve photographs and videos.
6. Keep damaged clothing or PPE when appropriate.
7. Save medical and employment records.
8. Document what work was happening before the fire.
9. Avoid signing documents you do not understand.
10. Speak with a New York construction accident attorney.

Workers should also tell medical providers if chemicals, smoke, gas, or other hazardous materials may have been involved.

That information may affect diagnosis and treatment.

Can You Receive Workers’ Compensation After a Construction Fire?

Many employees injured during construction work may qualify for New York workers’ compensation benefits.

Depending on the circumstances, benefits may address:

• Medical treatment
• Lost wages
• Temporary disability
• Permanent impairments

Workers’ compensation and a third-party personal injury claim are not necessarily the same.

If another contractor, property owner, equipment manufacturer, or other outside party contributed to the fire, a separate claim may be possible depending on the facts.

What If a Worker Dies in a Construction Fire?

Fatal construction fires can leave families facing devastating emotional and financial consequences.

Workers’ compensation death benefits may be available to qualifying dependents.

A wrongful death claim or other third-party claim may also be possible depending on how the accident occurred and who was responsible.

These cases require careful investigation because evidence concerning the fire’s origin and worksite responsibilities may be highly technical.

Frequently Asked Questions About NYC Construction Fires

What if the fire department determined the cause of the fire?

A fire department investigation can be important evidence, but it may not answer every question relevant to a civil construction injury claim.

A legal investigation may also examine contractor agreements, workplace safety responsibilities, equipment defects, and violations of construction regulations.

What if I was injured by smoke instead of flames?

You may still have a serious injury.

Smoke inhalation and toxic exposure can cause significant respiratory and neurological harm even when a worker never comes into direct contact with flames.

What if my coworker accidentally started the fire?

You may still have workers’ compensation rights.

The broader investigation may also examine whether unsafe site conditions, inadequate training, missing fire prevention measures, or another company’s conduct contributed to the accident.

What if an electrical problem caused the fire?

Electrical fires may require investigation of wiring, temporary electrical systems, maintenance, installation practices, and potentially defective equipment.

More than one contractor or company may be involved.
