Work at Height Rescue Plans — Why Every Fall Arrest Job Needs One (2026)

The Legal Requirement: You Must Plan for Rescue

The Work at Height Regulations 2005 are clear. Regulation 4 requires that work at height is properly planned, and that planning includes the selection of work equipment and — critically — planning for emergencies and rescue. A fall arrest system that stops someone falling is not the end of the safety chain. If the harness does its job and arrests a fall, you are left with a conscious or unconscious person hanging in mid-air, and you need a way to recover them.

The single most important point to understand is this: you must not rely on the emergency services as your rescue plan. Dialling 999 is not a rescue plan. The fire and rescue service has no legal duty to rescue your worker, may not have the right equipment, may not be able to reach the casualty in time, and could be many minutes away. The Health and Safety Executive (HSE) is explicit that the responsibility to plan and resource rescue sits with the employer, on site, before work starts.

If a fall is possible and could be arrested by a harness, you must have your own means of getting that person down quickly. Where you cannot, you have not complied with the regulations — regardless of how good your fall prevention is.

Why Speed Matters: Suspension Trauma

The reason rescue has to be fast is a medical condition known as suspension trauma — also called orthostatic intolerance or suspension syncope. It is the central justification for every rescue plan, and every operative working at height should understand it.

When a person hangs motionless and upright in a harness after a fall, the leg straps restrict blood flow back to the heart. Blood pools in the legs, the volume circulating to the brain drops, and the casualty can become faint, lose consciousness and deteriorate quickly. Movement normally helps pump blood back up the body, but a suspended, possibly injured or unconscious casualty cannot move. Prolonged motionless suspension is dangerous and can be fatal.

This is why prompt recovery is so important. The casualty often needs to be reached and recovered within minutes — not left hanging while someone fetches equipment or waits for an ambulance. The exact time a person can safely tolerate suspension varies with the individual and the situation, but the safe assumption for planning is simple: treat every suspension as time-critical and get the person down as fast as you safely can.

What a Rescue Plan Must Cover

A rescue plan is not a single sentence in a risk assessment saying "rescue casualty." It is a worked-through procedure specific to the job. A competent plan answers the following questions:

• Who will carry out the rescue? You need trained, competent rescuers physically present on site for the duration of the work — not someone who has to drive over. Lone working on fall arrest jobs is a serious red flag because there is no one to perform the rescue.
• What method and equipment will be used? This might be a dedicated rescue kit with a descent or recovery device, a MEWP brought alongside the casualty, a second roped operative, or a controlled lowering system. The equipment must suit the actual scenario.
• How will help be summoned? Define how the alarm is raised, who is called, and how the emergency services are alerted to support — even though they are not the rescue plan itself.
• How will the casualty be recovered? The physical steps to reach the casualty, take their weight, release them from the fall arrest system and bring them to a place of safety.
• What happens after the rescue? Post-rescue casualty care, first aid, and getting the person to professional medical help.

Practical Points That Get Overlooked

The difference between a rescue plan on paper and one that actually works comes down to a handful of practical details that are easy to skip under time pressure.

• Equipment on site before work starts. Rescue kit must be present, checked and ready before anyone goes up — not something you order or fetch after an incident. If the rescue device is in the van at the depot, you do not have a rescue plan.
• Rescuers must be trained. Owning a rescue kit is not the same as being able to use it under pressure. Rescuers need formal training on the specific equipment, and the plan should be rehearsed so the team can perform it quickly in a real emergency.
• Plan for the specific scenario. A rescue from a sloping roof is different from a rescue inside a tower, from a confined space, or from a MEWP. Write the plan for the actual structure and position the worker will occupy, not a generic template.
• Trauma relief straps buy time, not safety. A suitable harness fitted with suspension trauma relief straps lets the casualty stand in a loop and ease pressure on the leg straps, which can buy valuable minutes. But they are an aid, not a substitute — a fast rescue is still essential.

MEWP-Specific Rescue Planning

Mobile elevating work platforms carry their own particular rescue scenarios, and these need to be planned for separately. Two issues come up repeatedly:

Secondary means of lowering. If the platform's primary controls fail with operatives elevated, you must have a plan and the means to bring the platform down. Most MEWPs have an auxiliary or emergency lowering function, and a ground-level rescuer needs to know exactly where it is and how to operate it. That knowledge has to be confirmed before work starts, not discovered during an emergency.

Entrapment against a structure. One of the most dangerous MEWP scenarios is the platform trapping the operator against an overhead beam, soffit or structure — particularly if a sudden movement pushes them onto the controls. Your plan must account for how a trapped or crushed operative is reached and released, and how the platform is moved away from the structure without making the entrapment worse. A trained ground rescuer with access to the emergency controls is essential.

Casualty Care After Rescue

Once the casualty is down, the job is not over. Anyone who has been suspended in a harness — even briefly — should be assessed and seen by medical professionals, because the effects of suspension and any pooled blood returning to circulation can develop after recovery.

Get medical help promptly and follow current first-aid and medical guidance. Importantly, ignore outdated advice. Old guidance suggested sitting a recovered casualty up slowly to avoid a sudden return of pooled blood to the heart, but that approach is no longer the recommended practice. Current first-aid guidance is to give appropriate first aid, keep the casualty monitored, and seek medical advice — let qualified medical responders manage positioning and treatment. Do not delay calling for medical help in order to follow a positioning ritual. The safe rule is to treat the casualty as you would any seriously injured person, summon professional help, and follow the up-to-date instructions of your first-aider and the emergency services.

Build It Into Your Paperwork and Your Toolbox Talk

A rescue plan is only effective if the people on site know it. That means it cannot live solely in a folder. It needs to flow through your job documentation and your daily briefing.

• Risk assessment. The risk of a fall and subsequent suspension should be identified, and the rescue arrangements recorded as a control measure.
• Method statement. The rescue method, equipment, named rescuers and procedure should be written into the RAMS for the job, specific to that site.
• Toolbox talk. Before work starts, brief the whole team on the rescue plan — who the rescuers are, where the kit is, how the alarm is raised, and the time-critical nature of suspension trauma. Everyone on site should know what to do in the first sixty seconds after a fall.

Documenting the rescue plan and recording that you briefed it is also your evidence of compliance. If the HSE asks how you planned for emergencies and rescue, your RAMS and signed toolbox talk are what demonstrate you met your duty under the regulations.

The Bottom Line

If a fall on your job could be arrested by a harness, the law expects you to have planned how to get that person down — fast, with your own people and your own equipment, before work begins. Suspension trauma means there is no time to improvise. A proper rescue plan, built into your RAMS, resourced on site and briefed in the toolbox talk, is both a legal duty and the difference between a near miss and a fatality. Get it written, get the kit on site, get your rescuers trained, and rehearse it before anyone clips on.
