What 29 CFR 1910.151 requires (plain English)
29 CFR 1910.151 sets the medical services and first-aid requirements for general industry. Its core is availability: where an infirmary, clinic, or hospital is not in near proximity to the workplace, a person or persons must be adequately trained to render first aid, and adequate first-aid supplies must be readily available.
The standard's most-cited provision addresses corrosive chemicals: where the eyes or body of any person may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing of the eyes and body must be provided within the work area for immediate emergency use. In practice this means plumbed or self-contained eyewash stations and safety showers close to where acids, caustics, and other corrosives are handled.
1910.151 works with the bloodborne pathogens standard (1910.1030) where first aid may involve blood exposure, the emergency action plan requirements (1910.38), and the hazard communication and substance-specific standards that identify which chemicals are corrosive. It ensures that when engineering and PPE controls fail, immediate response is at hand.
