The leading causes of construction site fires in New York City are not dramatic explosions — they are everyday oversights: debris accumulation, misused extension cords, improper fuel storage, and hot work without adequate clearance. The same habits that cause minor fires on small jobs cause catastrophic fires on large ones.

• Combustible debris accumulation: Cardboard, foam insulation scraps, wood framing waste — remove from every floor daily. Overnight accumulation feeds fires that start from small ignition sources
• Temporary heating equipment: Propane salamanders and electric heaters ignite combustible materials stored too close. Maintain 3-foot clearance around all temporary heat sources
• Electrical cord fires: Overloaded extension cords, cords run under debris piles, and loose connections in spider boxes generate heat that ignites surrounding material
• Fuel spills: Equipment refueling on site — always use a funnel, never overfill, immediately absorb spills with dry material

• Inspect temporary heat sources at the start and end of every shift — clear the area around them
• Know the location of every fire extinguisher on your floor before you start work
• Never block stairwell exits, fire doors, or access to fire extinguishers with materials or equipment
• Report any burning smell, smoke, or discolored electrical insulation immediately — do not investigate on your own
