Read the notice OSHA published this morning and you will not find the word leukaemia.
You will find the phrase 'reduce compliance burdens,' which the agency gives as one of three reasons for revising the benzene standard at 29 CFR 1910.1028. The other two are newer technology and clearer language [1].
That framing is not itself wrong. Respiratory-protection requirements written into a substance-specific standard genuinely can duplicate the general respiratory standard OSHA wrote later, and duplication genuinely is a burden nobody benefits from. Aligning 1910.1028 with 29 CFR 1910.134 is the stated fix [1].
What the notice does not do is set that burden next to the thing the standard is for.
Benzene causes acute myeloid leukaemia. The reason the benzene standard carries its own respirator language at all is that the substance kills through the blood rather than the lungs, at concentrations a worker cannot smell.
The document reopens the record for 30 more days, to August 27, under Docket No. OSHA-2025-0023. It describes consultations with the Advisory Committee on Construction Safety and Health held on April 1 and May 19, then asks the public to comment on the Committee's recommendations [1].
Procedurally it is clean. The context is what makes it worth writing down.
This is the fourth carcinogen standard OSHA has moved in six days. Notices on 1,3-butadiene, on methylenedianiline and on the 13 Carcinogens standard all published on July 22.
Any one of them, read alone, is a technical alignment. Four of them in a week is a program.
One limit, stated plainly: this newsroom is not claiming the permissible exposure limit is being changed. The notice does not touch it, and we checked. What we are recording is that a set of standards written specifically because the substances cause cancer is being revised under a heading about burden - and that the comment window on the fourth one closes August 27.
