The glove(s) shall then be twisted several times, duct taped and thus sealed. (9) Sealing the Contaminated Items. The glovebag shall be tied off to contain the asbestos material prior to the glovebag being detached from the area where the asbestos was removed within the bag. (10) Containerizing the Glovebag. The sealed glovebag shall be placed into at least a six (6) mil plastic bag, sealed airtight and transferred from the regulated abatement work area as per Section 56-8.9, for disposal as asbestos waste. (11) Failure. The requirements of Section 56-8.2(g) shall be complied with in the event of glovebag losing seal or integrity. (b) Dry Removal or Dry Disturbance.
