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

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

1. Pre-Demolition Planning:

   • Conduct a thorough site assessment to identify potential hazards, including structural weaknesses, hazardous materials, utilities, and nearby structures.
   • Develop a comprehensive demolition plan outlining demolition methods, sequence of activities, safety measures, and emergency procedures.
   • Obtain necessary permits, approvals, and notifications from regulatory authorities and stakeholders.

2. Hazardous Material Assessment:

   • Conduct surveys and testing to identify and assess the presence of hazardous materials such as asbestos, lead-based paint, PCBs, and mercury.
   • Develop a hazardous material management plan to safely remove, handle, and dispose of hazardous materials in accordance with regulatory requirements.

3. Structural Stability:

   • Assess the structural integrity of the building or structure to be demolished, including foundations, load-bearing walls, and floor slabs.
   • Implement structural shoring, bracing, or reinforcement measures as needed to stabilize the structure and prevent unplanned collapses.

4. Utility Disconnection:

   • Identify and coordinate the disconnection and relocation of utilities such as electricity, gas, water, and telecommunications to prevent accidental damage or disruptions during demolition.

5. Site Securing and Access Control:

   • Secure the demolition site with fencing, barricades, and signage to restrict access and prevent unauthorized entry by pedestrians and vehicles.
   • Establish controlled access points and implement security measures to deter trespassing and vandalism.

6. Environmental Protection:

   • Implement erosion and sediment control measures to prevent soil erosion, runoff, and contamination of waterways during demolition activities.
   • Install dust suppression systems, barriers, and covers to minimize airborne dust emissions and mitigate the spread of pollutants.

7. Safety Equipment and Training:

   • Provide workers with appropriate personal protective equipment (PPE) such as hard hats, safety glasses, gloves, hearing protection, and respiratory protection.
   • Conduct comprehensive safety training for workers involved in demolition activities, emphasizing hazard recognition, safe work practices, and emergency procedures.

8. Emergency Preparedness:

   • Develop and communicate emergency response plans, including evacuation procedures, emergency contacts, and first aid protocols.
   • Ensure availability and accessibility of firefighting equipment, medical supplies, and emergency communication devices on-site.

By implementing these precautions before and during demolition, construction companies can minimize risks, prevent accidents, and ensure the safe and successful completion of demolition projects.
