Asbestos Inspector: Certification as an inspector authorizes a licensed asbestos consultant to review facilities' records and perform visual inspection or surveillance of facilities; to identify, document or inventory materials suspected of containing asbestos; to collect bulk samples for asbestos analysis and to provide direct supervision to non-certified individuals collecting bulk samples. A person does not need to be certified as an inspector to perform visual observations of an area that previously has been identified as containing interior ACM or that previously has been assigned to contain interior ACM and that is being inspected to identify changes in the physical condition of that interior ACM. However, no touching or taking of samples is permitted without a certificate as an inspector. A person who conducts a visual inspection to determine whether a response action is complete shall be certified as a project monitor.

Asbestos Project Monitor:  Certification as a project monitor authorizes a licensed asbestos consultant to function in the capacity of on-site representative of the facility owner or other persons, interpret project specifications or abatement management plans, monitor and evaluate contractor or employee compliance with applicable regulations or specifications and ensure that abatement projects are properly conducted and completed. The project monitor shall not also function as the asbestos contractor or as an employee of the asbestos contractor on the same asbestos abatement project for which he is the project monitor.
