(29) “Lead-safe work practices” means a prescribed set of activities that, taken together, ensure that any work that disturbs a painted surface on a structure constructed prior to 1978 generates a minimum of dust and debris, that any dust or debris generated is contained within the immediate work area, that access to the work area by non-workers is effectively limited, that the work area is thoroughly cleaned so as to remove all lead-contaminated dust and debris, and that all such dust and debris is disposed of in an appropriate manner, all in accordance with the methods and standards established by the Mayor by rule consistent with applicable federal requirements, as they may be amended.
