through the tape. In this manner, the contaminated tools may be placed directly into the next glove bag without being cleaned. Alternatively, the sleeve with the tools in it can be placed in a bucket of water, opened underwater and dried without releasing asbestos into the air. This water shall be handled as asbestos- contaminated waste. Rags and scrub brushes cannot be cleaned in this manner and should be discarded with the asbestos-contaminated waste. No more than one use of a glove bag shall be permitted.

18. With removed insulation I the bottom of the bag, twist the bag several times and tape it to keep the material in the bottom during removal of the glove bag from the pipe.

19. Slip a six mil disposal bag over the glove bag (still attached to the pipe). Remove the tape and open the tope of the glove bag and fold it down into the disposal bag.

20. All surfaces in the work area should be cleaned using disposable cloths wetted with wetting agent. These cloths shall be disposed of or rinsed thoroughly to eliminate visible accumulation of debris. Then, when these surfaces have been allowed to dry, all surfaces shall be cleaned again using a HEPA filtered vacuum. If no mini-enclosure was built, then the entire room shall be cleaned.

21. Place any contaminated articles or debris into the bag with the waste.

22. Twist the top of the bag closed, fold this over, and seal with duct tape. Label the bag with labels prescribed by 40 CFR Part 61, Subpart M of the USEPA, 29 CFR 1926 of OSHA and 49 CFR — Parts 100-199 of the US DOT Hazardous Waste Hauling regulations.

G. ENCAPSULATION (Not Applicable)

Encapsulation constitutes spraying friable asbestos-containing material with a liquid sealant (not including paint) that helps bind the asbestos together with other material components to adhere it firmly to the building structure.

1. The requirements of this section are set forth in order to prevent the contamination of the building environment which may be caused by improperly performed asbestos encapsulation work.

i. Encapsulation shall not be performed where:

a. Asbestos-containing material is friable, damaged, or deteriorating; b. Effective long-term inspection of the encapsulated site cannot be assured; c. The source of asbestos is highly accessible to building occupants and damage to materials is possible; d. The asbestos-containing material does not adhere well to the substrate;
