Interior Demolition Safety

Key Hazards

• Contact with concealed electrical, gas, water, or communication lines
• Removing a load-bearing or stabilizing component
• Falling ceilings, partitions, fixtures, and stored material
• Silica, lead, asbestos, mold, and nuisance dust exposure
• Cuts and punctures from sharp metal, glass, nails, and debris
• Workers or occupants entering active demolition zones

2–3 Minute Talk Script

Interior Demolition Safety requires workers to recognize the task-specific hazards before work begins and to use the controls established for the project.

The crew should confirm the approved demolition scope, survey information, utility controls, structural limits, hazardous-material results, debris route, ventilation, lighting, and occupied-area protection before work starts.

Walls, ceilings, floors, chases, and fixtures should be opened using methods that account for concealed services and prevent uncontrolled collapse.

Workers should not remove columns, braces, bearing walls, joists, fire protection, or other structural and life-safety components unless the plan specifically addresses them.

Dust should be controlled at the source with wet methods, local exhaust, HEPA collection, barriers, and respiratory protection required by the exposure plan.

Debris should be removed frequently using containers and routes that control sharp objects, weight, falling material, and interaction with occupants or other trades.

Temporary lighting, safe access, floor-opening protection, housekeeping, and exclusion zones should be maintained as walls and finishes are removed and conditions change.

Work should stop when an unknown utility or suspect material is found, the structure moves, demolition extends outside the approved scope, dust escapes containment, or occupants enter the controlled area.

Safety Reminders

• Confirm scope, utilities, and structural limits.
• Treat concealed spaces as potentially hazardous.
• Do not remove structural components without approval.
• Control dust and suspect materials.
• Remove sharp and heavy debris frequently.
• Maintain lighting, access, and opening protection.
• Keep occupants and other trades outside the demolition zone.

Ask the Crew

• What utilities and structural components may be concealed?
• What hazardous-material controls are required?
• How will dust be contained and removed?
• What route will debris take through the building?
• What unexpected condition requires immediate shutdown?
