OSHA Extends Reporting Rules for Construction Chemical MDA
Published Date: 2/18/2025
Notice
Summary
OSHA is asking for public feedback to keep collecting paperwork from construction companies about handling 4,4'-Methylenedianiline (MDA), a chemical used in construction. This extension means employers must keep tracking and reporting safety info to protect workers without new costs or changes. Comments are open until April 21, 2025, so everyone affected has a chance to weigh in.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
Worker notification, medical exams, and inspection protections
If you work where MDA is used, the standard requires your employer to notify you in writing of exposure-monitoring results within 5 days, inspect exposed body parts for dermal exposure, train you at assignment and at least yearly, and provide medical exams (initial, periodic, emergency, and follow-up). Your employer must also make exposure-monitoring and medical-surveillance records available to you and your designated representative.
Continued MDA paperwork and compliance duties
If you run a construction business that handles 4,4'-Methylenedianiline (MDA), you must keep doing specific recordkeeping and paperwork required by the MDA in Construction Standard (29 CFR 1926.60). The rule requires employers to perform exposure monitoring (initial, periodic, additional), notify each worker in writing of monitoring results no later than 5 days after receiving results, routinely inspect hands/face/forearms for dermal exposure, maintain written compliance and emergency plans, run a respiratory protection program per 29 CFR 1910.134, label MDA-containing materials and contaminated clothing containers, inform and provide information to launderers, post warning signs, train workers at initial assignment and annually, provide medical examinations, and keep exposure-monitoring and medical-surveillance records available to OSHA, NIOSH, workers, and their representatives.
Slight reduction in estimated paperwork burden and costs
OSHA is asking OMB to extend approval of the information collection and reports an adjusted total burden decrease from 1,012 hours to 954 hours (a 58-hour reduction) and a decrease in capital cost from $152,658 to $150,486. The notice lists 330 respondents, 2,395 responses, an estimated total burden of 954 hours, and estimated operation and maintenance cost of $150,486.
