§ 1-94 Maintenance of Decontamination Enclosure Systems and Barriers.
RCNY § 1-94
The following procedures shall be followed during the conduct of abatement activities on asbestos projects: (a) All plastic barriers inside the work place and partitions constructed to isolate the work area from occupied areas shall be inspected by the asbestos handler supervisor at least twice per shift.
(b)Smoke tubes shall be used to test the integrity of the work area barriers and the decontamination enclosure systems daily at a minimum both before abatement activity begins and at the end of each shift. A visual inspection of the barriers, including the use of differential manometers, shall be considered acceptable as a back-up test.
(c)Damage and defects in the decontamination enclosure system shall be repaired immediately. The decontamination enclosure system shall be maintained in a clean and sanitary condition at all times.
(d)At any time during the abatement activity, if visible emissions are observed, or elevated asbestos fiber counts outside the work area are measured, or if damage occurs to barriers, abatement shall stop. The source of the contamination shall be located, the integrity of the barriers shall be restored, and visible residue shall be cleaned up using appropriate HEPA vacuuming and wet cleaning procedures immediately.
(e)Inspections (including all inspections and testing required by subdivision (b) of this section), observations, and unusual incidents (e.g. barrier damage, contamination beyond the work area, etc.) must be documented in the abatement contractor’s log by the asbestos handler supervisor and in the project air sampling log.
(f)The daily inspection to ensure that exits have been checked against exterior blockage or impediments to exiting as per 15 RCNY § 1-81(t) shall be documented in the abatement contractor's log.
(g)If exits are found blocked, abatement activities shall stop until the blockage is cleared. (Amended City Record 4/28/2022, eff. 5/28/2022; amended City Record 1/15/2025, eff. 2/14/2025)
