To whom does the responsibility of documenting worker exposure primarily fall?

The responsibility of documenting worker exposure primarily falls to the building owner. This duty is grounded in the regulatory framework surrounding asbestos management, which mandates that building owners are responsible for ensuring the safety and health of workers on their properties. Under laws and regulations regarding hazardous materials, it is the building owner's responsibility to maintain comprehensive records of any known asbestos presence and the associated exposure risks.

While contractors, site supervisors, and construction managers play significant roles in the implementation of safety protocols and procedures, they are usually acting on behalf of the building owner or in accordance with the policies put in place by the owner. Therefore, the underlying accountability for documenting and managing worker exposure to asbestos rests with the building owner, who bears the ultimate legal and ethical obligation to protect workers and ensure compliance with safety regulations.
