Re:Updates to 527 CMR

Attached are recent updates approved by the Board of Fire Prevention Regulations for 527 CMR Sections 4, 9, 12, 16, and 20.

The following information is provided to assist you.

527 CMR 4.04(9)(d) - this section captures a change to the direct vent requirements to be in conformance with the national code. Also, a typographical error was corrected and this caused the regulation to be renumbered.

527 CMR 9.03(C) - has allowed for new exceptions regarding aboveground storage tanks in conformance with pre-fabricated tanks and containment systems.

527 CMR 12 - provides information from an earlier version of the National Electric Code with respect to grounding. Please share this section with your local wiring inspector.

527 CMR 16 - has been modified to capture requirements on model rocket storage and the ATF requirements and now incorporates the NFPA document on high powered model rocketry.

527 CMR 20 - regulation has been modified to be in conformance with newer construction heaters and provides further clarification to the requirements.

If you have any questions on any of the above contact the Technical Services Unit at 978-567-3375 or in Western MA at 413-587-3191.
