What important factor should be assessed prior to construction when asbestos is present?

The assessment of the level of asbestos contamination is crucial prior to construction because it directly affects the safety protocols that must be established to protect workers and occupants. Understanding the extent of contamination allows contractors to determine the appropriate safeguards, remediation methods, and regulatory compliance required.

Identifying the level of contamination informs decisions such as whether to encapsulate or remove the asbestos, the need for specialized removal teams trained in handling hazardous materials, and the necessity for air quality monitoring. This assessment is foundational to mitigate health risks associated with asbestos exposure, which can include serious respiratory diseases and cancers.

While having a safety manual, a hazardous waste disposal plan, and evaluating a contractor's experience are important factors in a construction project, they are secondary to determining the specific risks posed by asbestos contamination. Without first assessing the contamination level, it’s challenging to implement effective safety measures and ensure compliance with health regulations.
