(a) low-risk abatement and containment activities, with the exception of situations covered by 105 CMR 460.160(A)(3);

(b) exterior abatement activities;

(c) interior common area abatement and containment work, with the exception of situations covered by 105 CMR 460.160(A)(3); and

However, occupants in these situations must stay out of the work area until those activities are completed, and the authorized person performing them has cleaned up at the end of each workday, in accordance with 105 CMR 460.160(D).

(3) Occupants must be out of the dwelling unit for the workday, but need not be relocated, during abatement and containment work in interior common areas in situations in which the occupants of the unit undergoing abatement and/or containment have no second standard means of egress into and out of the residential premises.

(4) Exceptions to 105 CMR 460.160(A)(1) through (3) may be granted pursuant to specified conditions established on a case-by-case basis by the State Program or code enforcement agency, upon a finding that such occupancy will not endanger or materially impair the health of residents.

(B) Deleaders and authorized persons shall adhere to all health and safety requirements specified in 454 CMR 22.00: Deleading and Lead-safe Renovation Regulations.

(C) Worksite Preparation.

(1) Abatement Worksite Preparation. Authorized persons performing abatement work other than low-risk abatement activities shall prepare the worksite in accordance with the requirements of 105 CMR 460.000, 454 CMR 22.00: Deleading and Lead-safe Renovation Regulations and procedures set out in training materials approved by the Director.

(2) Low-risk Abatement/Containment Worksite Preparation.

(D) Clean-up.

(1) Final Clean-up. A final clean-up shall be performed by each authorized person doing abatement work that is not low-risk at the end of all his or her abatement work. Authorized persons shall wait at least two hours after completion of all their abatement work to perform final clean-up. Any low-risk abatement and/or containment activities, or structural repairs for interim control planned to take place after other abatement work shall begin only after the last final clean-up. Final clean-up shall at minimum consist of a HEPA-filtered vacuuming, followed by a wet mopping/sponging, and a second HEPA-filtered vacuuming, performed in accordance with training materials approved by the Director.

(2) Low-risk Abatement/Containment Clean-up. Authorized persons performing low-risk abatement and/or containment activities are responsible for clean-up of all work areas in which they worked, in accordance with training approved by the Director. Owners or owners' agents performing structural repairs for interim control must clean up all work areas in which they work, in accordance with educational materials for interim control approved by the Director.

(E) Relocated occupants of a dwelling unit or residential premises undergoing abatement for full compliance or interim control may resume occupancy, and new occupants may begin occupancy of a vacant dwelling unit or residential premises undergoing abatement for full compliance or interim control, upon the determination of a lead inspector or risk assessor that the dwelling unit has successfully met the conditions of a reoccupancy reinspection in compliance with 105 CMR 460.760(A).
