At its Aug. 28 meeting the IRC tag took formal votes on multiple proposals arising in the 2024 code cycle. The tag approved several mechanical and refrigerant-related amendments, adopted revised intake wording for ventilation, and tabled a substantial revision on dwelling-unit fire sprinkler language for further work.

Key outcomes (motions and final disposition)

- Carbon monoxide/reference amendment (state amendment relocation): The tag voted to approve a proposal to relocate and reformat existing state amendment language for carbon-monoxide provisions into the 2024 code layout. Motion to approve was made and seconded; the motion passed by voice vote.

- Refrigerant and mechanical code correlation (Proposal 040): The tag approved amendments that align the 2024 IRC with proposed changes for A2L refrigerants and related IMC provisions. A tag member moved to approve and the motion passed by voice vote.

- Refrigerant/ventilation text (Proposal 041): The tag initially tabled this proposal for revision and to await the proponent’s availability. The proponent (Eric Vandermee) later joined the meeting; after clarifying that some definitions and table references required cleanup, the tag voted to approve the proposal with the expectation that staff and the proponent would coordinate editorial/correlation changes prior to final drafting.

- Boiler and water-heater installations (Proposal 042): The tag approved edits clarifying that boilers and water heaters installed with refrigeration systems must be installed per ASHRAE/IMC/ASHRAE 15. The motion to approve passed by voice vote.

- Light ventilation and heating language (GP2044): The tag approved a revision that reintroduced a 2021 amendment’s intake-opening language into the reorganized 2024 code, with a small wording correction to align with the 2024 model text. Motion to approve carried by voice vote.

- Dwelling-unit fire sprinkler rewrite (Proposal 045): The group did not finalize this item. After significant discussion about whether to adopt the full chapter-29 language or preserve the existing appendix approach, the tag voted to table the proposal to the next meeting so staff and proponents can reconcile references (including whether to reference section P2904.1). The tabled motion passed.

Procedure and next steps

Several proposals required cross-code correlation (IMC/IRC) and editorial fixes (wrong section references, non-editable cut-and-paste images of definitions). In multiple cases the tag approved substantive direction but asked staff to coordinate with proponents on clean-up changes before the final rulemaking documents are prepared. Some items were explicitly tabled to a follow-up meeting on Sept. 2 to allow time for those clarifications.

Vote record notes

Most votes were taken by voice and not recorded as roll call in the transcript. Where motions were moved and seconded, the transcript records the mover and second in the discussion; full roll-call tallies with member-by-member votes do not appear in the transcript.

Ending: The tag closed the meeting after tabling the remaining items and scheduling a follow-up session to finish the outstanding proposals.
