OSHA Seeks Input on Methylenedianiline Safety Data Rules
Published Date: 6/29/2026
Notice
Summary
The Department of Labor is asking for public feedback on rules that help keep workers safe from a chemical called 4,4′-Methylenedianiline in general workplaces. Employers need to track exposure, offer medical checkups, and keep records. Comments are open until July 29, 2026, and this process helps make sure the rules are clear and not too costly.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Employers Must Track MDA Exposure
If your business uses 4,4'-Methylenedianiline (MDA) in general industry, you must monitor worker exposures to stay within permissible exposure limits, give medical examinations and training, and keep exposure-monitoring and medical records. The Department of Labor estimates this information collection covers 10 respondents, 585 responses, 319 annual burden hours, and $26,800 in annual other costs under OMB Control Number 1218-0184.
Paperwork Rule Protected by OMB Approval
The information collection is subject to the Paperwork Reduction Act and requires OMB approval (OMB Control Number 1218-0184). Under 5 CFR 1320.5(a) and 1320.6, businesses generally are not required to respond and cannot be penalized for failing to comply with a collection that does not display a currently valid OMB Control Number, and DOL seeks authorization for this ICR for three years.
