Summary
In short
- Near proximity is a response-time test, not a distance. Three to four minutes where serious injury is possible; up to fifteen where it is remote.
- The measurement that matters is how long emergency services actually take to reach your site, at the times you operate, not the distance on a map.
- Trained first aiders are required for each shift and each operation where other arrangements have not been made, which is where night and weekend cover usually fails.
- OSHA's 2019 interpretation states that adequate first aid training includes direct pressure, hemostatic dressings and tourniquets in certain situations.
- ANSI Z308.1 distinguishes Class A kits for common workplace injuries from Class B kits for workplaces with high risk of severe injury, which include tourniquets.
- Where a site is rural or distant from a hospital, the employer is required to provide an acceptable type of emergency transportation.
What it is
What it is
When are trained first aiders required?
Under 29 CFR 1910.151(b), where there is no infirmary, clinic or hospital in near proximity used for treatment of all injured employees, a person or persons must be adequately trained to render first aid, with adequate supplies readily available. The construction equivalent is 1926.50(c).
What does near proximity mean?
OSHA interprets it as a response time rather than a distance. Where accidents resulting in suffocation, severe bleeding or other life-threatening or permanently disabling injury are possible, three to four minutes from injury to first aid is required. Where such outcomes are remote, as in an office, up to fifteen minutes may be reasonable.
When to use it
When to use it, and when not to
This records first aid training and currency. The needs assessment behind it is separate.
Use it for
- Training and certifying first aiders for each shift and operation
- Recording site-specific additions: the substances, machinery and hazards present
- Tracking certification currency and scheduling refresher training
- Recording assessment of practical competence rather than attendance alone
- Reviewing after a change in shift patterns, staffing, site location or hazards
Not for
- The first aid needs assessment, which determines how many first aiders and what provision is required
- First aid kit and equipment inspection, which checks supplies and their accessibility
- The first aid report, which records treatment given to an individual
- Bloodborne pathogens training, which is a separate requirement where exposure is anticipated
- Emergency response planning, which addresses site-wide scenarios
Standards
What it is built against
First aid obligations are performance-based, with the interpretation supplying the numbers.

What it does not cover
- The first aid needs assessment, determining how many first aiders and what provision the site requires.
- Kit and equipment inspection, checking supplies, accessibility and expiry.
- The first aid report, recording treatment given to an individual.
- Bloodborne pathogens training, a separate requirement with vaccination and post-exposure elements.
- Emergency response planning, addressing site-wide scenarios rather than individual injury.
Filling it in
Filling it in well
Measure the response time, cover the site's actual hazards, and check cover across every shift.
Time an emergency vehicle to the point of work at the hours you operate, including site access, gatehouse and finding the building. Record it, because that number determines whether trained first aiders are a requirement or a choice, and it is the evidence if the question is ever asked.
Generic first aid covers bleeding, burns, fractures and unresponsiveness. What it does not cover is the chemical on your site with a specific first aid measure, the machinery producing crush or amputation injuries, the confined space rescue interface, or the cold store. Section 4 of each safety data sheet is the source for the chemical additions.
OSHA's interpretation states adequate training includes direct pressure, hemostatic dressings and tourniquets in certain situations. Where the site has cutting, machinery or vehicle hazards capable of catastrophic bleeding, Class B kit contents and the training to use them are the proportionate provision rather than an enhancement.
The requirement extends to each shift and each operation. A site with fifteen trained first aiders can still have a night shift with none, or one who is on annual leave. Cover should be reported as the number of shifts with adequate cover rather than as a total, which conceals precisely the gap that matters.
Audit findings
Common audit findings
First aid findings concentrate on cover, currency and content.
| Finding | Clause | What fixes it |
|---|---|---|
| Near proximity assessed from distance rather than measured response time. | 1910.151(b) | Time an actual response at operating hours; the test is minutes to treatment. |
| First aid cover reported as a headcount rather than by shift. | 1910.151(b) | Report shifts with adequate cover; totals conceal night and weekend gaps. |
| Training generic, with no site-specific chemical or machinery content. | 1910.151(b) | Add from safety data sheet section 4 and from the site's injury mechanisms. |
| Bleeding control not covered where catastrophic bleeding is credible. | OSHA interpretation 2019 | Direct pressure, hemostatic dressings and tourniquets, with Class B kit contents. |
| Certification lapsed with no tracking of expiry. | ISO 45001 cl.7.2 | Track currency per person and per shift; certifications expire quietly. |
| No bloodborne pathogens provision for designated first aiders. | 1910.1030 | Where aid may involve blood exposure, the programme including vaccination offer applies. |
| Remote site without arrangements for emergency transportation. | 1910.151(b) | Where distant from a hospital, acceptable emergency transportation must be provided. |
| Kit class not matched to the severity of credible injuries. | ANSI Z308.1 | Class B where high risk of severe injury; Class A is the general minimum. |
| Training assessed by attendance rather than practical demonstration. | ISO 45001 cl.7.2 | Assess practically; first aid is a skill that decays and is used under stress. |
| Contractors and lone workers outside the cover arrangement. | ISO 45001 cl.8.1.4 | They are on site and frequently in the least covered locations and hours. |
Worked case
Case in point: the hospital four minutes away
A manufacturing site assessed its first aid needs and concluded that trained first aiders were not strictly required, because a hospital with an emergency department was about two miles away and the site was in a town.
The response time was never measured. When it finally was measured, after a serious injury, the sequence took considerably longer than the map suggested: the call handling, the dispatch, the drive, the arrival at a gatehouse with a barrier, locating the correct building on a site with three entrances, and reaching a machine in the middle of a production hall.
None of those steps are unusual and none appear on a map. OSHA's threshold is three to four minutes from injury to first aid where a life-threatening outcome is possible, and the assessment had compared a distance against a requirement expressed in minutes.

FAQ
Frequently asked questions
How do we know if we need first aiders?+
Measure the response time. OSHA interprets near proximity as three to four minutes from injury to first aid where suffocation, severe bleeding or other life-threatening or permanently disabling injury is possible, and up to fifteen minutes where such outcomes are remote. Where the measured response exceeds the applicable threshold, trained first aiders are required.
What does the clock actually cover?+
From injury to treatment. That includes someone recognising what happened, making the call, the service dispatching and travelling, entering the site, and reaching the casualty at their actual location. A gatehouse, a barrier, three entrances and a production hall all sit inside that window, and none of them appear on a map.
Does first aid cover extend to every shift?+
Yes. Trained first aiders are required for each shift and each operation where other arrangements have not been made. A site total conceals the shift with none, which is usually nights or weekends, and which is also when response times are typically longer and supervision lower.
What does bleeding control training need to include?+
OSHA's 2019 interpretation states that adequate first aid training includes instruction on applying direct pressure, using hemostatic dressings, and using tourniquets in certain situations. Where the site has machinery, cutting or vehicle hazards capable of catastrophic bleeding, Class B kit contents under ANSI Z308.1 and the training to use them are the proportionate provision.
What should be added to a generic course?+
The site's specific injury mechanisms and chemicals. Section 4 of each safety data sheet gives the first aid measures for the substances present, which generic training will not cover. Add the machinery injury types the site can produce, the confined space or height rescue interface where relevant, and cold or heat exposure where those apply.
The agents
What the agents do with it
The record certifies first aiders. What fails is cover measured as a headcount and a response time nobody timed.
Tracks certification currency per person and reports cover by shift rather than as a site total.
Holds the needs assessment including the measured response time, and connects site chemicals to the first aid content required.
Links kit provision and class to the credible injury severity, and schedules inspection of supplies and accessibility.
Brings contractors and lone workers into the cover arrangement, since they occupy the least covered hours and locations.
