105 CMR 460.110
Lead Hazards: Abatement and Containment Requirements for Full Compliance
(A) Violations of 105 CMR 460.000 also constitute violations of the State Sanitary Code
(M.G.L. c. 111, § 127A) which requires corrections to be made in a workmanlike fashion, including
restoring all parts of the residential premises to the condition they were in before occurrence of any
such violations. Authorized persons shall perform work in accordance with the requirements of 105
CMR 460.000 and 454 CMR 22.00: Deleading and Lead-safe Renovation Regulations, and the
safe work practices and procedures set out in training, educational materials, or in additional guidance
approved by the Director or the Department of Labor Standards. Repainting with non-lead-based paint
without abatement or containment of the offending paint, plaster, or other material, does not constitute
compliance with M.G.L. c. 111, § 197.
(B) Abatement or containment of lead-based paint, other coating, plaster or putty must be performed
as follows:
(1) Loose lead-based paint, other coating, plaster or putty on surfaces that are neither moveable
impact surfaces nor accessible mouthable surfaces must be abated intact or contained.
(2) Lead-based paint, other coating, plaster or putty on moveable impact surfaces shall be
abated, or, with the exception of window sashes that are part of an interior habitable area or which
need to be useable to meet ventilation requirements under the state Building Code (780 CMR),
contained with an approved covering. In the case of metal windows, only lead-based paint or
other coating on the sills shall be abated or contained. Other moveable impact surfaces on metal
windows must be intact or, if loose, made intact.
(3) Lead-based paint, other coating, plaster or putty shall be abated on accessible, mouthable
surfaces to a height of five feet, and four inches in from each edge, or such surfaces may be
contained. Encapsulants applied to suitable accessible, mouthable surfaces must be applied to the
entire surface, rather than only to a height of five feet and only four inches in from each edge.
(4) Lead-based paint, other coating, plaster or putty shall be abated on friction surfaces at all
points of potential friction where the components meet. Stair treads must be abated in their entirety
to the wall or balusters, or such surfaces may be covered. Friction surfaces may not be
encapsulated.
(C) Only authorized persons shall perform abatement or containment activities. The following
authorized persons may perform the following categories of abatement and containment activities:
(1) Licensed deleaders may perform all abatement and containment activities in accordance with
the requirements of 105 CMR 460.000 and 454 CMR 22.00: Deleading and Lead-safe
Renovation Regulations.
(2) Authorized persons and owners and owners’ agents authorized to perform moderate-risk
abatement may perform all moderate- and low-risk abatement and/or containment activities,
subject to the requirement of 105 CMR 460.110(C)(3), in accordance with the requirements of
105 CMR 460.000 and 454 CMR 22.00: Deleading and Lead-safe Renovation Regulations.
(3) An owner or owner’s agent authorized to perform only low-risk abatement and/or
containment activities may perform only the activities set out at 105 CMR 460.175(A), subject to
the requirements of 105 CMR 460.110(C)(4), and in compliance with all the requirements of 105
CMR 460.000.
