  • (b) any drop sheets that are contaminated with asbestos dust, waste or debris are wetted.

• (2) All asbestos dust, waste or debris and any drop sheets that are contaminated with asbestos dust, waste or debris shall be placed in a container referred to in section 5.19.11.

5.19.5 If a glove bag is used for the removal of asbestos insulation from pipes, ducts and similar structures, an employer shall ensure that

• (a) the glove bag is sealed to prevent the release of asbestos fibres into the work area;

• (b) the glove bag is inspected for damage or defects immediately before it is attached to the pipe, duct or similar structure and at regular intervals during its use;

• (c) all waste from asbestos-containing material that is on surfaces is washed to the bottom of the glove bag and all exposed asbestos-containing material is encapsulated when it is inside the glove bag;

• (d) the glove bag is evacuated using a vacuum cleaner that is equipped with a HEPA filter to remove the air inside the bag prior to the removal of the glove bag; and

• (e) after the glove bag is removed, all exposed surfaces are cleaned with a damp cloth and a vacuum cleaner that is equipped with a HEPA filter.

Decontamination

• 5.19.6 (1) Before leaving a work area that is contaminated with asbestos-containing material, an employee shall
