Most California workplaces have a first aid kit on the wall, and most of the managers responsible for it could not tell you who approved its contents, who on the shift is trained to use it, or what happens in the twenty minutes between a serious injury and the arrival of an ambulance. Title 8, Section 3400 is a short standard, but it asks those exact questions, and inspectors ask them too, usually right after an injury. This article covers what Section 3400 requires, what Section 1512 adds for construction, and when a nurse or clinic is actually required. This article was written with clinical input from Zennin Sedacey-McNeil, LVN (VN 741259), McNeil Safety Consulting’s staff nurse, whose certifications in IV Therapy/Blood Withdrawal (IV), Infection Preventionist (IP), Treatment Nurse (TX), and Director of Staff Development (DSD) inform the clinical guidance below.
Who Is Covered
Section 3400 sits in the General Industry Safety Orders and applies to every California employer. There is no size threshold and no industry carve-out. Construction employers are additionally covered by Section 1512 in the Construction Safety Orders, which is more prescriptive about kit contents and posted emergency numbers. Electrical workers are covered by additional medical services provisions in Sections 2320.10 for low-voltage work and 2940.10 for high-voltage work.
What Section 3400 Requires
The standard has six operative subsections, and each one is a separate citation item:
- Medical personnel for advice. Subsection (a) requires the employer to ensure the ready availability of medical personnel for advice and consultation on matters of industrial health or injury. This does not mean a nurse on site. It means you have a physician, clinic, or occupational health provider you can actually reach, and that the arrangement exists before you need it.
- Trained first aid providers. Subsection (b) applies in the absence of an infirmary, clinic, or hospital in near proximity to the workplace that is used for the treatment of all injured employees. In that case a person or persons must be adequately trained to render first aid, with training equal to that of the American Red Cross or the Mine Safety and Health Administration. The standard does not put a mileage or minute figure on “near proximity.” I recommend treating trained providers as the default and the proximity exception as something you justify in writing.
- First aid materials approved by a physician. Subsection (c) requires adequate first aid materials, approved by the consulting physician, readily available on every job, kept sanitary and usable, inspected frequently, and replenished as necessary. The words “approved by the consulting physician” are the ones most employers cannot document. A kit that came from a supply catalog with an ANSI label on it is not, by itself, physician approved.
- Drenching and eye flushing. Subsection (d) requires suitable facilities for quick drenching or flushing of the eyes and body within the work area wherever a person may be exposed to injurious corrosive materials.
- Stretchers and blankets. Under subsection (e), the Division may require stretchers and blankets or other adequate warm covering unless ambulance service is available within 30 minutes under normal conditions.
- Advance provisions for prompt treatment. Subsection (f) requires effective provisions, made in advance, for prompt medical treatment in the event of serious injury or illness, using one or a combination of three things: a communication system for reaching a doctor or emergency medical service, such as 911, where the system or the employees using it can direct responders to the injured person’s location; readily accessible on-site treatment facilities suited to the injuries you can reasonably anticipate; or proper equipment for prompt medical transport when that is necessary and appropriate.
What Section 1512 Adds for Construction
Section 1512 restates the core duties for construction sites and fills in detail. Where more than one employer is on a site, each employer is responsible for ensuring emergency medical services are available to its own employees. Each employer must ensure a suitable number of appropriately trained persons to render first aid. Each employer must inform its employees of the procedure to follow in case of injury or illness.
On kit contents, Section 1512(c) gives you a choice: the contents are determined by an employer-authorized licensed physician, or they follow the table in the section, which scales supplies by crew size in bands of one to five, six to fifteen, sixteen to two hundred, and more than two hundred employees. The larger bands add items such as forceps, a flashlight, and an emesis basin, and the top band adds portable oxygen with breathing equipment. The section also requires the telephone numbers of a physician and an alternate, hospitals, ambulance services, and fire protection services to be posted near the job telephone, and it requires a two-way voice emergency communication system for buildings and structures five or more floors or 48 feet or more above or below ground level.
When a Nurse or Clinic Is Required
The honest answer is that Section 3400 never requires an on-site nurse or clinic. It requires access to medical advice, trained first aid providers where no nearby facility exists, approved materials, and a plan for prompt treatment. An on-site clinic is one of the three ways to satisfy subsection (f), not a mandate.
Where I do see a nurse earn a place is in operations with a high injury frequency, remote or after-hours work, large headcounts, or exposure-driven medical surveillance programs under other standards. In those settings a licensed nurse does three things a first aid volunteer cannot: applies clinical judgment to whether an injury is first aid or needs a physician, which also affects how the case is recorded on the Log 300; runs the surveillance program consistently; and serves as the consulting physician’s on-site point of contact so subsection (a) is more than a phone number on a poster. Our staff nurse’s view is that the most common clinical failure is not the missing supply but the untrained responder who moves a suspected spinal injury or applies a tourniquet to a wound that needed direct pressure.
Where Employers Fall Short
- No documented physician approval. Ask the consulting physician to review and sign a one-page kit contents list. Keep it with the kit inspection log.
- Trained responders who are not on shift. Two certified people on day shift and none on nights is a gap.
- Expired or contaminated supplies. “Frequent inspection” is not defined, so set a monthly schedule and initial the log.
- No way to direct 911. Subsection (f)(1) is about directing responders to the injured person. Post the physical address, gate codes, and a site map at every phone and in every crew truck.
- Bloodborne pathogens overlooked. Designated first aid providers with occupational exposure are covered by Section 5193, which brings the exposure control plan, hepatitis B vaccination, and post-exposure procedures into play. Section 5193(f) allows an employer to defer the vaccination offer for providers who render first aid only as a collateral duty, but only if the exposure control plan says so and the vaccine is made available no later than 24 hours after a first aid incident involving blood.
- No transport plan for remote work. If an ambulance cannot reach the crew in 30 minutes, decide in advance who drives, in what vehicle, to which facility, and with what stabilization equipment.
What Inspectors Look For
After a serious injury, the inspector will ask who rendered first aid, what training that person had, where the kit was, and how long it took to reach emergency services. They will look at the kit for expired items and blood contamination, ask for the physician approval, ask for first aid training certificates, and check that emergency numbers are posted. On a construction site they will compare the kit against the Section 1512 table for your crew size.
What to Do Now
- Name your consulting physician or occupational health provider in writing and confirm how employees and supervisors reach them for advice.
- Have that physician review and sign the contents list for every first aid kit, or adopt the Section 1512 table on construction sites and document the crew size band you are using.
- Identify at least one trained first aid responder for every shift and every remote crew, and calendar recertification dates.
- Post the site address, access instructions, and emergency numbers at every phone and in vehicles used by field crews.
- Write a one-page serious injury response procedure covering 911, on-site treatment, and transport, and walk it through with supervisors.
- Fold designated first aid providers into your bloodborne pathogens exposure control plan and decide, in writing, whether you will offer hepatitis B vaccination up front or under the collateral-duty deferral in Section 5193(f).
