(d) Containment or abatement, and daily and final cleanup of paint, plaster or other accessible structural material required under this section, whether undertaken for full compliance or as an interim measure under an emergency lead management plan, shall be conducted only by a contractor licensed by the department of labor standards, except that the owner of premises or the owner's agent, acting pursuant to regulations promulgated by the director specifying the conditions under which owners or their agents may undertake such containment or abatement, need not be licensed to engage in such activities. Any person who is not licensed may undertake containment or abatement activities only after successful completion of a course of instruction approved by the commissioner in consultation with the director detailing the proper methods and health hazards of containment or abatement and final cleanup of paint, plaster or other accessible structural material; provided further, that all containment or abatement activities by an unlicensed person shall be inspected and approved after completion by a licensed inspector. Such regulations shall include, but not be limited to, the removal of doors, windows, woodwork or other elements or fixtures containing dangerous levels of lead and shall address the presence of residents during deleading and cleanup; provided, that in no instance shall paint containing such dangerous levels of lead be stripped or scraped from the doors, windows, woodwork, elements or fixtures while residents are on the premises. The director shall make available to the public standard guidelines relative to owner deleading activities made permissible pursuant to this section.
