In a school building, a written project design is required when friable ACM to be abated exceeds what amount?

In the context of asbestos abatement in school buildings, a written project design is mandated when the amount of friable asbestos-containing material (ACM) to be removed exceeds three square feet. This requirement is in place to ensure that proper planning, oversight, and safety considerations are addressed when dealing with hazardous materials.

The necessity for a project design at this threshold helps to protect the health of workers and occupants by ensuring that the abatement process is conducted according to established guidelines and regulatory standards. This includes detailing methods for safely handling and disposing of the asbestos, as well as monitoring and controlling the work environment to minimize exposure.

Understanding these thresholds is crucial for compliance with asbestos regulation and for maintaining a safe environment within educational facilities.
