What are the precaution which may be considered before and during demolition.

Before and during demolition activities, several precautions should be considered to ensure the safety of workers, the public, and the surrounding environment:

1. Pre-Demolition Planning: Conduct a thorough pre-demolition assessment to identify potential hazards, such as asbestos, lead-based paint, structural weaknesses, and underground utilities. Develop a comprehensive demolition plan that includes site-specific safety measures, demolition methods, and waste disposal procedures.

2. Structural Stability: Assess the structural integrity of the building or structure to be demolished to identify any weak points or unstable areas. Implement temporary bracing, shoring, or reinforcement measures as needed to prevent collapse or unintended structural failures during demolition.

3. Hazardous Material Removal: Identify and remove hazardous materials, including asbestos, lead-based paint, PCBs, and other contaminants, from the building prior to demolition. Follow proper procedures for handling, containment, and disposal of hazardous materials to prevent exposure and environmental contamination.

4. Utilities Disconnection: Disconnect and cap off all utilities, including electricity, gas, water, and sewer lines, before commencing demolition to prevent accidental damage or exposure to live electrical wires or leaking pipes.

5. Site Security and Access Control: Secure the demolition site with fencing, barricades, and signage to prevent unauthorized access and protect the public from potential hazards. Control traffic and pedestrian access around the demolition site to minimize the risk of accidents and injuries.

6. Dust and Debris Control: Implement dust suppression measures such as water spraying, dust barriers, and containment systems to minimize airborne dust and debris during demolition. Use proper personal protective equipment (PPE) such as respirators, goggles, and gloves to protect workers from dust exposure.

7. Noise and Vibration Monitoring: Monitor noise and vibration levels generated by demolition activities to ensure compliance with regulatory limits and minimize disturbances to neighboring properties and communities. Implement noise barriers, soundproofing measures, or work restrictions as needed to mitigate noise impacts.

8. Emergency Preparedness: Develop and communicate emergency response plans and procedures for addressing potential incidents such as fires, collapses, or injuries during demolition. Provide training to workers on emergency evacuation routes, first aid protocols, and communication procedures.

9. Environmental Protection: Implement erosion and sediment control measures to prevent soil erosion, runoff, and pollution from entering waterways. Properly manage and dispose of demolition waste, including concrete, wood, metals, and other materials, to minimize environmental impact and promote recycling and reuse.

By considering these precautions before and during demolition activities, contractors can minimize risks, ensure compliance with regulations, and protect the health and safety of workers, the public, and the environment.
