Asbestos

 

Demolishing a building with asbestos requires a very different approach compared to a standard demolition. Here's the proper way to handle it:

Absolute No to DIY: Due to the health risks of asbestos, attempting a DIY demolition is extremely dangerous. Asbestos abatement and demolition should only be carried out by licensed and certified professionals.

The Process:

1. Asbestos Abatement:

   • Inspection: A qualified inspector identifies all asbestos-containing materials (ACM) in the building. Samples are taken for lab analysis to confirm the type and asbestos content.
   • Abatement plan: A detailed plan outlines the removal process for each type of ACM, following regulations set by the Environmental Protection Agency (EPA) and Occupational Safety and Health Administration (OSHA).
   • Removal: Licensed asbestos abatement workers remove the ACMs using strict protocols to minimize dust generation. This may involve wetting the materials, using negative air pressure chambers, and proper bagging and disposal procedures.

2. Demolition Planning:

   • After complete asbestos abatement is verified, a separate demolition plan is created specific to the remaining structure. This plan incorporates standard demolition procedures alongside measures to prevent disturbing any residual asbestos dust.

3. Demolition with Caution:

   • Qualified crew: A licensed demolition crew with experience handling asbestos-containing structures carries out the demolition.
   • Dust control: Measures like water misting and covering exposed areas minimize dust generation during demolition.
   • Air monitoring: Air quality is continuously monitored to ensure asbestos fiber levels stay below safe limits.

4. Post-demolition:

   • Site cleaning: Meticulous cleaning ensures no asbestos fibers remain on the property. HEPA vacuums and other specialized techniques may be used.
   • Waste disposal: Asbestos waste is transported and disposed of in approved landfills following specific regulations.

Important considerations:

• Permits are required for both asbestos abatement and demolition.
• Notifications are typically required to inform the local municipality and potentially nearby residents about the project.
• Workers involved wear specific personal protective equipment (PPE) to prevent asbestos exposure.
