Text pulled from the eCFR, current as of 2026-10-14.
Question 1
A contractor is renovating a plant's water-treatment area. For three days, a crew will decant and mix a strong caustic cleaning solution that can splash onto the eyes and skin. The only eyewash station is in the site office trailer, across the yard from the mixing area. The safety technician is asked what the site needs before the work begins. Which action is required?
Show answer and source
Answer: A. Provide suitable quick-drenching or flushing facilities for the eyes and body within the mixing work area for immediate use
When workers' eyes or bodies may be exposed to injurious corrosive materials, the standard requires quick drenching or flushing facilities within the work area for immediate emergency use. A distant trailer eyewash, a small saline bottle, or a posted phone number does not meet that requirement.
Answer A rests on
29 CFR 1926.50(g)(opens ecfr.gov in a new tab)“(g) 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 shall be provided within the work area for immediate emergency use.”
Question 2
A utility contractor is sending a six-person crew to a remote site where the nearest clinic is a long drive away and no physician is reasonably accessible. The foreman says the site is covered because one crew member, Dana, 'took a first-aid class years ago' and has told the foreman so, though she holds no card and no record of the training exists. The company also keeps a fully stocked first aid kit in the truck. Based on the standard, what is the correct assessment of this arrangement?
Show answer and source
Answer: B. Not compliant, because with no reasonably accessible medical facility, the person available to render first aid must hold a valid first-aid certificate or equivalent training verifiable by documentary evidence
Because no infirmary, clinic, hospital, or physician is reasonably accessible, the standard requires a person with a valid first-aid certificate or equivalent training that can be verified by documentary evidence. Dana's unverified verbal claim is not documentary evidence, and a first aid kit does not replace a qualified person.
Answer B rests on
29 CFR 1926.50(c)(opens ecfr.gov in a new tab)“In the absence of an infirmary, clinic, hospital, or physician, that is reasonably accessible in terms of time and distance to the worksite, which is available for the treatment of injured employees, a person who has a valid certificate in first-aid training from the U.S. Bureau of Mines, the American Red Cross, or equivalent training that can be verified by documentary evidence, shall be available at the worksite to render first aid.”
Question 3
A contractor starts a 10-week building project in a rural area. The nearest clinic is more than an hour away by road, no physician is on site, and no one on the crew has first-aid training. The superintendent says the project is covered because the foreman has a cell phone to call an ambulance and the crew has a well-stocked first aid kit. Which action is required to meet the first-aid personnel requirement?
Show answer and source
Answer: D. Have a person with a valid first-aid training certificate, or training equivalent that can be verified by documentary evidence, available at the worksite to render first aid
When no infirmary, clinic, hospital, or physician is reasonably accessible in time and distance, the standard requires a person with valid first-aid training, verifiable by documentary evidence, to be available at the worksite. A kit, a phone, or advisory medical consultation does not satisfy that separate requirement.
Answer D rests on
29 CFR 1926.50(c)(opens ecfr.gov in a new tab)“In the absence of an infirmary, clinic, hospital, or physician, that is reasonably accessible in terms of time and distance to the worksite, which is available for the treatment of injured employees, a person who has a valid certificate in first-aid training from the U.S. Bureau of Mines, the American Red Cross, or equivalent training that can be verified by documentary evidence, shall be available at the worksite to render first aid.”
