Risk Assessment for Demolition Work

1. Hazard Identification

• Falling Materials: Risk of injury from materials falling during demolition.
• Hazardous Substances: Presence of chemical and biological substances that may be hazardous.
• Structural Collapse: Risk of accidental collapse of the structure being demolished.
• Utilities: Risk from live utilities such as gas, water, and electricity.
• Explosives: If used, pose a significant risk to workers and the surrounding area.
• Pedestrian Safety: Risk to pedestrians or other persons near the demolition site.

2. Risk Assessment

• Likelihood: High likelihood of falling materials and structural collapse if not properly managed.
• Severity: High severity due to potential for serious injury or fatality.

3. Control Measures

• Elimination: Remove all hazardous substances before demolition begins [1].
• Substitution: Use mechanical demolition methods instead of explosives where possible.
• Engineering Controls: Ensure structures are adequately shored, braced, or supported to prevent collapse [2]. Use enclosed chutes for material disposal [1].
• Administrative Controls: Designate a competent worker to oversee demolition [1]. Ensure all utilities are disconnected and confirmed in writing [1]. Conduct a thorough assessment of the building for hazardous substances and structural integrity [2].
• PPE: Provide appropriate personal protective equipment to all workers involved in demolition.

4. Monitoring and Review

• Regularly review the demolition plan and adjust as necessary to address any new hazards or changes in conditions.
• Conduct regular safety audits and inspections to ensure compliance with safety protocols.

5. Recommendations

• Training: Provide comprehensive training to all workers on demolition safety and emergency procedures.
• Signage: Install conspicuous warning signs to alert workers and the public of potential hazards [1].
• Emergency Preparedness: Develop and communicate an emergency response plan for potential incidents during demolition.

By implementing these control measures, the risks associated with demolition work can be significantly reduced, ensuring the safety of workers and the public.
