First Aid Needs Assessment for Construction: Getting Beyond One Kit and a Certificate

The Question With No Table Answer

The Health and Safety (First-Aid) Regulations 1981 require employers to provide adequate and appropriate first aid equipment, facilities and personnel — and deliberately decline to give a universal headcount table. What "adequate and appropriate" means is decided by your first aid needs assessment, and on a construction site that assessment has real work to do, because construction is precisely the environment where the generic office answer collapses: higher-hazard work, changing site conditions, spread-out work areas, shift patterns, lone tasks, and an ambulance response time that depends on where the site actually is.

The HSE's guidance (L74) is clear that higher-hazard environments like construction point toward first aiders with the full First Aid at Work qualification, in numbers that reflect the workforce and the risk — and that the assessment, not a poster, is what justifies your provision. If your site's answer is one kit in the office and whoever happens to hold a certificate, the assessment has not been done; it has been assumed.

What the Assessment Weighs

The hazards. What can plausibly happen here? Excavation and structural work, plant and vehicle movement, work at height, hot works, hazardous substances, confined spaces, work near water — each shifts the injuries you must be ready for and the equipment that readiness implies. A site with confined space entries needs rescue-integrated first aid arrangements; a site with widespread cutting and grinding should think hard about eye irrigation and serious bleed response.

The people and the numbers. Peak headcount, not average — including subcontractors, visitors and delivery drivers who are on your site when it goes wrong. Shift patterns and overtime matter: a first aider who leaves at 15:30 covers nothing about the concrete gang finishing at 19:00. So does the profile of the workforce — lone workers, young workers, anyone with known medical conditions the arrangements should anticipate.

The geography. How long does it take to reach a casualty at the far end of the site, and how long for an ambulance to reach the gate — and then the casualty? Linear sites, multiple work fronts and remote locations argue for first aiders distributed across the site and for kits (and sometimes AEDs) at work areas, not just in the welfare block. If access for emergency services involves gates, haul roads or an escort, the plan for meeting and directing them is part of first aid provision.

Cover. First aiders take leave, get sick and go to other jobs. The assessment plans for absence — enough trained people that the site is never uncovered, which in practice means more names than the bare minimum and a live view of who is actually present today.

Turning the Assessment Into Provision

The output is specific: how many first aiders at which qualification (FAW as the construction default, with EFAW acceptable where the assessment genuinely supports lower-risk pockets), where they are based, how they are contacted, what equipment sits where, and what the emergency procedure is. Kits stocked for your hazards, checked and restocked on a schedule that survives contact with reality. An AED is increasingly the norm on sites of any size — survival from cardiac arrest falls by roughly ten percent per minute without defibrillation, and the device only helps if people know it exists and where it lives. Eyewash where the assessment says so, burns provision near hot works, and travel kits for gangs working away from the fixed facilities.

Then make it visible: names and faces of first aiders on the notice boards and in the induction, green signage on the kit locations, the emergency procedure — including the site address and access instructions for the 999 call — printed where panicking people will look for it. In the moment, nobody reads the assessment; they read the wall.

Keep It Current, Test It Occasionally

A construction site is not the same site for long. Headcount doubles for the pour season, phases open and close, night working starts, the compound moves. Review the first aid needs assessment at those trigger points and at set intervals; check qualification expiry dates before they lapse rather than after; and update the boards when first aiders leave. Finally, walk the arrangements once in a while: pick a spot on site, imagine the casualty, and time the story — who is called, who responds, where the kit comes from, how the ambulance gets in. If the walkthrough stumbles, better to find out on a dry Tuesday than during the real thing.
