New York Codes, Rules and Regulations › Title 12 - DEPARTMENT OF LABOR › Chapter I - Industrial Board Of Appeals › Subchapter A - The Industrial Code › Part 56 - Asbestos › Subpart 56-4 - General Project Air Sampling And Laboratory Analysis Requirements › Section 56-4.12 - Unsatisfactory clearance air sample results

Current through Register Vol. 46, No. 28, July 10, 2024
If the regulated abatement work area clearance air
						sampling results are unacceptable, the following requirements apply:
(a) If the results of the inside work area
					 group of air samples are unsatisfactory, recleaning of regulated abatement work
					 area surfaces using wet methods, followed by another drying time period and
					 then collection and analysis of an additional full set (both inside and outside
					 work area samples) of clearance air samples is required (see section
					 56-9.2 
					 of this Part).
(b) If only the
					 results of the outside work area group of air samples is unsatisfactory,
					 clean-up of surfaces outside of the regulated abatement work area using
					 HEPA-vacuums and wet-cleaning methods shall be performed prior to collection
					 and analysis of an additional group of outside work area clearance air samples
					 as required by section
					 56-9.2 
					 of this Part.
(c) This
					 recleaning/clean-up and sampling process shall be repeated until satisfactory
					 clearance air sampling results have been achieved for all asbestos project
					 non-exempt regulated abatement work areas throughout the entire work site.
