Post Date: 02 Jan, 2019

Projects in China may use the following asbestos inspection, management and post-remediation clearance requirements in lieu of those required in Feature 11, Part 3.

a) Inspection requirements
On-site inspection is conducted by a knowledgeable professional. The inspection report must include: (1) Examination of building records, if existing, to evaluate portions of the building likely to contain Asbestos containing building materials (ACBM).
Visual assessment of suspected ACBM. (2) Tactile (touch) verification of suspected ACBM to determine whether they are friable (i.e., likely to become particles). (3) An inventory with all areas containing suspected ACBM. (4) A confirmation sample for areas that are not suspected ACBM is recommended.

b) Asbestos management plan
If the presence of asbestos is confirmed or suspected per the initial inspection, a plan needs to be written and implemented, containing at least the following elements: (1) A blueprint of the building and identification of suspected and confirmed ACBM. (2) Description of all abatement removal actions. (3) For ACBM left-in-place, description of management activities that may include: periodic structural check, painting, isolation of spaces with ACBM, encapsulation. (4) A surveillance and reinspection schedule (with a 3-year minimum periodicity) based on the status of the remediation and the integrity of the ACBM left in place, with special emphasis in potentially friable ACBM. (5) Description of preventative measures to minimize the risk of exposure to asbestos. (6) Notification (and sample, if deemed necessary) procedures in case of potential exposure due to the loss of integrity of ACBM. (7) Post-remediation clearance protocols, including air testing.

c) Post-abatement clearance
As described in the Asbestos Management Plan, post-abatement clearance must be stated, properly documented, and performed according to applicable standards.

Projects may achieve Feature 22, Part 1 by using uncovered trashcans if they are located directly underneath paper towel dispensers and at least one closed trashcan is additionally provided to collect waste other than paper towels. This does not apply to trashcans located in areas where food is prepared and stored (e.g., kitchens, pantries, etc.) as these recepticles must be closed to avoid pests.

Should pests eventually become an issue, the project commits to providing lids at trash receptacles immediately.
