310 CMR 33.05
Release of MSDS to Government Officials
(1) Departments of Public Health and Labor and Industries. All employers are hereby notified that
the Departments of Public Health and Labor and Industries shall have continual access to all MSDSs
filed with the Department via interlocking filing systems; thus, copies of all MSDSs filed with the
Department have been provided to these agencies upon entry in the system.
(2) Other Agencies of the Commonwealth. Any other state agency may file a written request for
MSDS information.
(a) Such request shall identify to the extent possible the name and location of each employer to
whom the request pertains, and each substance about which information is sought. Where specific
identification is not possible, the request should identify categories of employers or substances.
(b) The request shall contain a written justification explaining why the information is essential to
the performance of a duty to protect public health or safety, including:
1. a reference to the authority to be exercised, and
2. a statement of the actions proposed as performance of such a duty. A statement that the
information is essential to determine whether any additional actions are necessary shall be
sufficient, if accompanied by a summary of some or all contemplated actions the requesting
agency is authorized to take.
3. the specific reasons access to MSDS information is essential.
(c) The request shall be filed with the appropriate regional office of the Department.
(d) The Department shall make a written determination whether to release any MSDS
information. Copies of the determination shall be mailed to the requesting agency and to the
relevant employer(s). When an MSDS is released, it shall be accompanied by a statement advising
the recipient of the restrictions on disclosure of said MSDS.
(3) Imminent Threat.
(a) Where the Department determines that an imminent threat to public health or safety exists, it
may release a copy of any relevant MSDS information to any state agency with authority and
responsibility to act to respond to such threat, or to the municipal coordinator of the affected
municipality. Within five working days of such release, the Department shall prepare a written
statement outlining the basis for the determination that an imminent threat existed and notifying the
employer of the release of MSDS information.
(b) Where a municipal coordinator determines that an imminent threat to public health or safety
exists, the municipal coordinator may release a copy of any relevant MSDS to any official of the
same municipality if the municipal coordinator also determines that immediate access to the MSDS
information is critical to the other official's performance of a duty to protect public health or safety
(under existing statute, regulation, ordinance or by-law). Within five working days of such release,
the municipal coordinator shall prepare a written statement outlining the basis for the determinations
that an imminent threat existed and that such immediate access was critical, and notifying the
relevant employer(s) of the release. A copy of this statement shall be provided to the Department.
The municipal coordinator shall advise the recipient of the restrictions on disclosure of said MSDS
at the time of the release.
