For All Spaces: Option 1: Asbestos risk assessment For existing buildings constructed or last renovated before the enactment of laws banning the installation of asbestos- containing materials, and for buildings located where there is no local asbestos phase-out regulation, one of the following requirements is met: a. Project for which all asbestos has been removed in a prior renovation demonstrates that occupancy of the space is legally allowed. b. An investigation of the project space is conducted by an inspector certified under local regulation or a qualified professional with demonstrable experience where no local regulations apply. The investigation must provide the following, at minimum: 1. A list of locations where presumed asbestos containing materials (PACM) were found. 2. Confirmation of the presence of asbestos is performed through Polarized Light Microscopy (PLM) or Transmission Electron Microscopy (TEM) testing. The sample number and location follow applicable laws or recommendations of the inspector conducting the assessment. Materials having over 1% of asbestos are considered ACM. If analytical confirmation is not available or possible, all PACM are considered asbestos- containing materials (ACM). Option 2: Asbestos action plan If asbestos-containing materials (ACM) were found per the above, an action plan that contains the following is implemented: a. Notification of any works to relevant authorities and persons living, working or transiting in the vicinity of the building or space. b. Preventative measures against the formation and spread of asbestos fibers in the air during remedial work. c. Measures taken for workers’ protection during remediation activities, including but not limited to skin and respiratory protection. d.
