Section 228.141  Necessary and Practicable Safegards

Where the risk of public exposure to asbestos fiber from the dislodging of asbestos-containing materials is present, no demolition of a structure shall be initiated unless all safeguards necessary and practicable to reduce the emission of dust are taken.  Such procedures shall include, but are not necessarily limited to:

a)         Boilers and pipes and steel members insulated or fireproofed with asbestos-containing material shall be wetted and stripped before toppling of walls is begun.  This procedure shall be followed, where practicable, as to all other asbestos-lined surfaces.  Such asbestos waste shall be immediately bagged and disposed of in accordance with Section 228.121(d).

b)         When demolition by toppling occurs such reasonable enclosure for dust emission control as is compatible with the character of the structure shall be employed.

c)         Before the demolition or toppling of any section or wall of the structure, adequate wetting to suppress the dust shall be employed.

d)         Asbestos-containing debris shall not be dropped or thrown from any floor but shall be transported by dust-tight chutes or buckets. Asbestos-containing debris in chutes or buckets shall be sufficiently wetted to preclude dust dispersion at the point of discharge.

e)         All asbestos-containing debris shall be thoroughly wetted before loading into trucks, other vehicles or containers.  During transport such waste shall be enclosed or covered so as to prevent dust dispersion. Asbestos-containing debris shall be disposed by burial at a sanitary landfill.
