OSHA said it will hold informal public hearings on proposed rule changes covering respiratory protection for 16 substances, with hearings beginning August 19, 2026.
Key Facts
- The notice is a proposed rule from OSHA, published June 3, 2026.
- OSHA is scheduling informal public hearings on proposed rules covering 16 chemical substances and related standards.
- The hearings will begin on August 19, 2026.
- The notice says the proposed rules listed were published in the Federal Register on July 1, 2025, except for the Walking-Working Surfaces proposal.
- The topics include changes to respiratory protection medical evaluation requirements for certain types of respirators.
What Happened
OSHA issued a proposed rule notice announcing a series of informal public hearings on a broad set of pending actions, including changes to respiratory protection requirements for 16 chemical substances and related standards.
The notice says the hearings will begin on August 19, 2026. The page title also identifies the respiratory protection item as an amendment to the medical evaluation requirements for certain types of respirators.
Why It Matters
For chemical users, the notice signals that respiratory protection policy is moving into a formal hearing stage rather than remaining only in proposal form. That can affect how facilities plan respirator programs, medical surveillance workflows, and compliance timelines.
Buyers and EHS teams with exposure controls tied to listed substances should watch for changes that may affect respirator selection, fit testing, and medical clearance processes. The scope also suggests attention will remain on controls for carcinogens and other high-concern hazards.
Key Details
The substances and standards named in the notice include 1,2-dibromo-3-chloropropane; 1,3-butadiene; 13 carcinogens; acrylonitrile; asbestos; benzene; cadmium; coke oven emissions; cotton dust; ethylene oxide; formaldehyde; inorganic arsenic; lead; methylene chloride; methylenedianiline; and vinyl chloride.

The notice also references proposed rules on Safety Color Code for Marking Physical Hazards, Textiles, Sawmills, Safety Color Code for Marking Physical Hazards for Shipyard Employment, and Walking-Working Surfaces.
What To Watch Next
Facilities should monitor the hearing record and any follow-on OSHA actions for details that could change implementation burden or documentation requirements. This is especially relevant for operations that rely on tight respiratory protection programs across multiple regulated substances.
Procurement and EHS teams may want to review current respirator inventories, medical evaluation processes, and substance-specific exposure control plans so they are positioned to adjust quickly if the proposal advances.
Alliance's Take
For Alliance Chemical customers, this is a cue to review respirator-related compliance programs now, especially where employees handle substances named in the notice.
Teams should align procurement, medical surveillance, and training records so any OSHA changes can be absorbed without last-minute operational disruption.
