					 Access. Entry to the personal and waste decontamination system enclosures shall
					 be restricted to the asbestos contractors involved with the asbestos project,
					 appropriately certified employees of the asbestos contractors, authorized
					 visitors, police, fire and other public safety personnel.
(b) Waiting periods. Prior to beginning Phase
					 II B asbestos abatement work and upon completion of the construction of all
					 small and large size regulated abatement work area enclosures and
					 decontamination system enclosures, including establishment of the negative air
					 system, a four hour waiting period with negative air units operating shall be
					 required to insure that all barriers shall remain intact and secured to the
					 walls, ceilings, floors and fixtures.
(c) Waiting period exemption. The four hour
					 waiting period may be eliminated for exterior work where negative air is not
					 required.
(d) Inspection of
					 barriers. All barriers shall be inspected by the asbestos supervisor at least
					 twice daily, before the start of and following the completion of the day's
					 abatement activities. Inspections are also required on days when there is no
					 Phase II work or support activities scheduled. Inspections and observations
					 shall be documented by the asbestos abatement contractor's supervisor in a
					 daily project log.
(e) Repairs to
					 barriers and enclosures. Damage and defects in the barriers and enclosures
					 shall be repaired immediately upon discovery and shall be documented by the
					 asbestos abatement contractor's supervisor in a daily project log, prior to
					 resumption of abatement activities.
(f) Testing of barriers and enclosures. Smoke
					 tube testing to ensure the effectiveness of all isolation barriers, personal
					 decontamination system enclosures, waste decontamination system enclosures and
					 regulated abatement work area enclosures shall be performed prior to the
					 beginning of abatement activities and at least once a day thereafter until
					 satisfactory clearance air sampling results have been obtained. Negative air
					 pressure ventilation units shall be in operation during this testing. Testing
					 of barriers and enclosures is not required on days when there are no Phase II B
					 or cleaning activities scheduled. Test results, observations and any
					 modifications shall be documented by the asbestos abatement contractor's
					 supervisor in a daily project log.
(g) Loss of enclosure integrity. If visible
					 emissions or water leaks are observed outside of the regulated abatement work
					 area, or if a glovebag, tent or enclosure of any type fails or loses its
					 integrity, work shall be stopped and the following procedures shall be
					 followed:
(1) Isolation and critical barrier
					 construction. Isolation and critical barriers shall be constructed as follows:
(i) Isolate HVAC systems. The HVAC systems
					 shall be shut down immediately and all openings shall be sealed with at least
					 six mil fire-retardant plastic sheeting and duct tape.
(ii) Isolate uncontaminated areas.
					 Passageways to uncontaminated areas of the building or structure shall be
					 sealed with at least six mil fire-retardant plastic sheeting and duct
					 tape.

					 barriers. Critical barriers within 25 feet of the regulated abatement work area
					 shall be installed as per section
					 56-7.11 
					 of this Part.
