1926.50: Medical Services and First Aid on Construction Sites

By Black Belt Safety Editorial Team Official text as of octubre 15, 2026 Data updated noviembre 6, 2026 3 min read

In plain words:

Construction employers must plan for prompt medical care before a project starts, including access to medical advice, first aid supplies and a way to get injured workers to a doctor or call an ambulance. If no clinic or hospital is reasonably close, a certified first aid person must be on site, and eye and body flushing must be provided where corrosive materials are used.

(ii)

(A) When using a communication system in an area that does not automatically supply the caller's latitude and longitude information to the 911 emergency dispatcher, the employer must post in a conspicuous location at the worksite either:

(1) The latitude and longitude of the worksite; or

(2) Other location-identification information that communicates effectively to employees the location of the worksite.

(B) The requirement specified in paragraph (f)(2)(ii)(A) of this section does not apply to worksites with readily available telephone land lines that have 911 emergency service that automatically identifies the location of the caller.

(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. Open (g) 133 citations

First aid supplies are required to be easily accessible under paragraph § 1926.50(d)(1). An example of the minimal contents of a generic first aid kit is described in American National Standard (ANSI) Z308.1-1978 “Minimum Requirements for Industrial Unit-Type First-aid Kits”. The contents of the kit listed in the ANSI standard should be adequate for small work sites. When larger operations or multiple operations are being conducted at the same location, employers should determine the need for additional first aid kits at the worksite, additional types of first aid equipment and supplies and additional quantities and types of supplies and equipment in the first aid kits.

In a similar fashion, employers who have unique or changing first-aid needs in their workplace may need to enhance their first-aid kits. The employer can use the OSHA 300 log, OSHA 301 log, or other reports to identify these unique problems. Consultation from the local fire/rescue department, appropriate medical professional, or local emergency room may be helpful to employers in these circumstances. By assessing the specific needs of their workplace, employers can ensure that reasonably anticipated supplies are available. Employers should assess the specific needs of their worksite periodically and augment the first aid kit appropriately.

If it is reasonably anticipated employees will be exposed to blood or other potentially infectious materials while using first-aid supplies, employers should provide personal protective equipment (PPE). Appropriate PPE includes gloves, gowns, face shields, masks and eye protection (see “Occupational Exposure to Blood borne Pathogens”, 29 CFR 1910.1030(d)(3)) (56 FR 64175).
