💥 Demolition Safety
Topic: Safe demolition practices Duration: 10-15 minutes Required: Demolition requires special training and procedures
The Hazards
Demolition is one of the most dangerous construction activities:
- Structural collapse - Buildings can collapse unexpectedly
- Falling debris - Materials fall from height
- Asbestos/lead - Hazardous materials exposure
- Utilities - Live utilities in walls
- Dust - Silica, lead, asbestos dust
Pre-Demolition Planning
Engineering Survey
- Structural assessment - How building is constructed
- Hazardous materials - Asbestos, lead survey
- Utilities - Locate and disconnect utilities
- Adjacent structures - Protect nearby buildings
- Demolition plan - Written plan for demolition
Utility Disconnection
Before demolition:
- Electrical - Disconnected and verified
- Gas - Disconnected and verified
- Water - Disconnected and verified
- Sewer - Disconnected and verified
- Other utilities - All utilities disconnected
Verify: Test to ensure utilities are dead.
Structural Stability
During Demolition
- Progressive demolition - Remove in logical sequence
- Don't overload - Don't remove structural members prematurely
- Monitor stability - Watch for signs of instability
- Support as needed - Temporary supports if needed
- Stay clear - Keep personnel away from collapse zone
Falling Debris Protection
- Debris chutes - For material removal
- Netting - Catch falling debris
- Barricades - Keep personnel away
- Warning signs - Alert to hazards
- Hard hats - Required at all times
Hazardous Materials
Asbestos/Lead
- Survey completed - Identify hazardous materials
- Abatement - Remove before demolition (if required)
- PPE - Respiratory protection if needed
- Training - Workers trained on hazards

Structural Collapse
Demolition can cause unexpected structural collapse. Never enter a building being demolished. Stay in safe zones.
