UNDERSTAND THE DEFINITION

What counts as work at height?

Work at height is about the possibility of falling from one level to a lower level and being injured. There is no general two-metre threshold in the definition.

The simple test

Ask: without the precautions in place, could somebody fall a distance liable to cause personal injury?

  • Working from a ladder or elevated platform can count.
  • Working on a roof or beside an open edge can count.
  • Falling through a fragile surface can count.
  • Falling into a floor opening, shaft or hole can count.

Do not use height alone

A fall risk can exist above ground, at floor level beside an opening, or where a surface can fail beneath a person.

The common myth"It only becomes work at height above two metres" is not the definition.
Worker breaking through a fragile roof surface
AFall from an edge

An exposed roof, platform or opening edge can create a direct fall to a lower level.

BFall through a surface

A rooflight or fragile sheet can fail beneath a person even when there is no open edge nearby.

CFall into an opening

A floor void, stairwell, shaft or excavation can create work-at-height risk from the level you are standing on.

Trace the fall

Do not decide yes or no yet. For each situation, identify where the person could fall to. This makes you use the definition rather than rehearse the later check.

Decision habitStart by tracing the possible fall route. If there is no route to a lower level or through a surface, ask whether the task still creates any fall distance liable to cause personal injury.
EXTENDED LEARNING · CITY & GUILDS AC 3.1

Work at height: follow the possible fall, not a two-metre rule

Work at height means work in any place where, if precautions were not in place, a person could fall a distance liable to cause personal injury. The definition is about the possibility and consequence of a fall to a lower level.

Clearly work at height

  • working on a scaffold, ladder, roof or MEWP
  • working beside an open edge where a person could fall
  • working over an excavation, stairwell or floor opening
  • working where a person could fall through a fragile surface

Important detail

There is no general two-metre threshold in the legal definition. A short fall can still cause serious injury. The question is whether a person could fall a distance liable to cause personal injury.

Walking up and down a permanent staircase in normal use is not usually treated as work at height simply because levels change, but work on or beside unprotected stairs can create a fall risk.

Below ground still countsA worker beside an unprotected excavation is working where a fall to a lower level could occur. Work at height is not limited to being above ground level.
Exam focusIf an option says “work at height only starts above 2 metres”, it is incorrect. Trace the potential fall route and decide whether personal injury could result.

RESPONSIBILITIES

Who must do what?

Work at height is controlled by planning and supervision, but the worker also has direct responsibilities in the way equipment is used and how danger is reported.

People controlling the work

  • Plan and organise the work at height.
  • Make sure it is appropriately supervised.
  • Use competent people for the task.
  • Select and provide suitable equipment and arrangements.

The worker / operative

  • Use work equipment and safety devices in line with training and instructions.
  • Report work-at-height activities or defects that could endanger safety.
  • Co-operate with agreed safety measures and site arrangements.
  • Do not improvise around a known safety defect.

What the worker's legal duties mean in practice

Official HSE guidance boils the employee role down to three behaviours that matter on every height task.

Take reasonable careThink about your own safety and anyone who could be affected by what you do.
Co-operate and reportWork with the agreed arrangements and report safety hazards or dangerous defects to the employer or person in control.
Use equipment properlyUse equipment and safety devices in line with training and instructions. If an instruction appears unsafe, stop and seek further instruction before continuing.

The five-second pre-use scan

A quick worker check does not replace formal inspection. It helps you notice an obvious problem before committing to the task.

1Right type?

Does the equipment suit the task and how you need to work?

2Sound condition?

Look for damage, missing parts or failed safety features.

3Safe place?

Check the supporting surface, traffic, openings and nearby hazards.

4Know what to do?

Use it as trained and report defects or changing conditions.

A useful distinctionThe person controlling the work arranges the safe system. The worker still has to use it correctly and raise anything that could make the task unsafe.
EXTENDED LEARNING · CITY & GUILDS AC 3.2

Employee responsibilities: use the safe system and speak up when it fails

The Work at Height Regulations place major duties on employers and those who control the work, but employees also have direct duties. A safe scaffold or MEWP only protects people if workers use it as intended.

What the employer/control side arranges

  • avoid work at height where reasonably practicable
  • plan and supervise unavoidable work
  • select suitable equipment using the hierarchy
  • ensure people are competent for the work/equipment
  • provide inspection, maintenance and safe access arrangements

What the employee must do

  • follow training, instructions and the agreed method
  • use work equipment and safety devices correctly
  • carry out user checks required by the system
  • report defects, missing protection or changing conditions
  • take reasonable care of themselves and others
Do not “make do”.A worker should not stand on an improvised platform, remove a guardrail, overreach from a ladder or continue with damaged access equipment simply because the job is nearly finished.
ExampleIf a scaffold is tagged or identified as incomplete, the employee does not decide it looks “safe enough”. Keep out and report it so the competent person responsible can make the scaffold safe.

CONTROL MEASURES

Control the risk in the right order

The safest response is not automatically a harness. Work through the hierarchy systematically and give priority to protection that protects everyone exposed.

FirstAvoidDo the work from ground level or another position that removes the need to work at height where reasonably practicable.
If unavoidablePreventUse an existing safe place or suitable equipment that prevents a fall.
If risk remainsMinimiseReduce the distance and consequences of a fall using suitable measures.

Collective protection

Protects more than one person without each individual having to act for the protection to work.

ExamplesGuarded scaffold platforms, edge protection and a protected MEWP platform.

Personal protection

Relies on the individual using, fitting or connecting the system correctly.

ExamplesWork restraint and fall-arrest systems. They sit lower in the preference order where stronger collective measures are reasonably practicable.

Control the nine hazard areas

The control has to fit the actual hazard. Use these as practical starting points, then follow the risk assessment, equipment instructions and site arrangements.

Dropping tools & debrisSecure materials and tools; use toe boards, mesh or other containment where appropriate; keep people out of the drop zone.
Stability of laddersUse the right ladder on firm, level ground; set and secure it correctly; avoid overreaching and side loading.
Overhead cablesIdentify lines before work starts; plan access and plant routes; use the agreed controls and safe clearances; isolate or reroute where practicable.
Fragile roofsAvoid stepping on fragile material; use planned access, suitable platforms, covers and edge protection, with clear warning and segregation.
ScaffoldsUse a complete, stable, properly guarded platform with safe access; ensure required inspections are carried out by a competent person.
Internal voidsGuard or securely cover openings and keep access routes arranged so people cannot step or fall into the void.
EquipmentSelect equipment that is suitable, stable and strong enough; maintain and check it; remove defective items from use and report them.
The working areaKeep the area tidy and stable; consider weather, slippery surfaces, access, ground condition and anything that could affect balance or equipment stability.
Other peopleCoordinate trades, use exclusion or segregation where needed, control falling-object risk and stop others interfering with access equipment.

Around 75 degreesThis corresponds to the one-in-four rule for a leaning ladder.

Angle is only one part of safe use: firm level ground, effective securing, suitable condition and sensible positioning still matter.

EXTENDED LEARNING · CITY & GUILDS AC 3.4

Control work at height in the correct hierarchy

Work at height controls follow a clear order: avoid the work at height where reasonably practicable; where it cannot be avoided, prevent falls; where a fall risk remains, minimise the distance and consequences. Collective protection normally takes priority over personal protection.

1 · Avoid

Do the work from the ground where reasonably practicable — for example pre-assemble at ground level, use extendable tools or reposition equipment so routine work can be completed from a safe level.

2 · Prevent

Use an existing safe place of work or suitable equipment that prevents a fall: properly erected scaffold, MEWP, guardrails, edge protection, secured covers or other collective protection.

3 · Minimise

If a fall cannot be fully prevented, reduce distance and consequences with suitable systems such as safety nets, airbags or personal fall-arrest equipment selected for the task.

HazardTypical controls
Open edge / voidavoid exposure; guardrails and toe boards; secured covers; controlled access
Fragile surfaceavoid access; identify/mark; use suitable platforms/crawling boards/MEWP; provide protection below/around where required
Falling objectssecure tools/materials, toe boards, brick guards, exclusion zones, controlled storage
Ladder useuse only where suitable; firm level base, correct angle for leaning ladders, secure against movement, maintain three points of contact where practicable
Weathermonitor wind/ice/rain; stop when conditions make equipment or footing unsafe
Collective before personal.Guardrails and a properly erected work platform protect everyone using the area without each person having to take individual action. A harness protects only the correctly connected wearer and may require a rescue plan.
Harness is not the default answer.Fall restraint can prevent a person reaching the edge; fall arrest acts after a fall begins. Both require proper selection, anchorage, training and planning.

THE REGULATION

The Work at Height Regulations 2005

This is the central regulation controlling work at height and the selection and use of suitable work-at-height equipment.

Regulation 4 · Plan and organise

Work at height must be properly planned, appropriately supervised and carried out safely. Planning should include foreseeable emergencies and rescue.

Regulation 5 · Competence

People involved need the skills, knowledge and experience appropriate to the work, or suitable supervision while being trained.

Regulation 6 · Avoid, prevent, minimise

First avoid work at height where reasonably practicable; if it cannot be avoided, prevent falls; if risk remains, minimise the distance and consequences.

Regulation 7 · Select suitable equipment

Selection should reflect the task, duration, frequency, working conditions, access needs and risks to everyone where the equipment will be used.

Remember the full nameWork at Height Regulations 2005.
Worker at a protected edge using work equipment

More of the Work at Height Regulations in practice

You do not need to memorise every regulation number to work safely, but these themes explain why the site controls are there.

Regulation 9 · Fragile surfaces

Work on or near a fragile surface needs suitable measures to prevent a person falling through it.

Regulation 10 · Falling objects

Take suitable steps to prevent materials or objects falling where they could injure someone, or otherwise prevent people being struck.

Regulations 12–13 · Inspection

Certain work equipment and places of work at height must be inspected. Construction working platforms over 2 metres have specific inspection intervals and event-triggered checks.

Regulation 14 · People at work

Workers must report safety hazards and use work equipment and safety devices properly in line with training and instructions.

The wider legal pictureOther health and safety law can also apply to the job, including the Health and Safety at Work etc. Act, Management Regulations, CDM and equipment law. The Work at Height Regulations 2005 remain the central framework for work-at-height decisions.

EXTENDED LEARNING · CITY & GUILDS AC 3.5

The Work at Height Regulations 2005 and suitable equipment

AC 3.5 expects you to know the regulation controlling the use of suitable equipment for work at height. The Work at Height Regulations 2005 apply where there is a risk of a fall liable to cause personal injury.

What “suitable” means

Equipment must be appropriate for the task, height, duration, load, access needs and site conditions. It must be strong and stable enough, correctly positioned, maintained and inspected where required. The safest practical option should be selected using the work-at-height hierarchy.

Ladders are not banned

A ladder or stepladder can be suitable for low-risk, short-duration work, or where existing site features mean more protective equipment is not justified, provided the risk assessment shows it can be used safely. It still needs a firm base, suitable condition and protection from movement.

Competence and inspection

Planning, equipment selection, assembly and inspection must be carried out by people with the necessary competence for their role. Workers should use equipment as trained and report defects.

Leaning-ladder reminder

A common positioning guide is around 75 degrees — the one-in-four rule. Angle is only one factor; securing, ground, access, condition and the task itself still matter.

Exam focusIf asked which regulation controls work at height equipment, the answer is the Work at Height Regulations 2005. PUWER can also apply to work equipment generally, but AC 3.5 is specifically mapped to the work-at-height regulation.
