Working at Height in Ireland: Current Duties and Safer Planning

Working at height starts wherever a fall from a work location could cause personal injury. The risk can arise on a roof, a ladder or a platform, and also beside an excavation at ground level. The distance of a possible fall is important to the assessment, but Irish law does not make a universal two-metre threshold the trigger for all work-at-height duties.

The current general rules are in Part 4 of the Safety, Health and Welfare at Work (General Application) Regulations 2007. Some older documents cite the 2006 Work at Height Regulations; the Irish Statute Book register records that instrument as revoked. This guide therefore uses Part 4 of the 2007 regulations and the Health and Safety Authority's work-at-height guidance. More specific construction requirements may also apply to a particular site.

Decide whether the task is work at height

The Part 4 definition in regulation 94 covers work in a place, including access to or exit from it, from which a person could fall a distance liable to cause personal injury if the protective measures were not taken. That can include a below-ground location. The HSA's examples range from changing ceiling lamps and sheeting a lorry to working near an open cellar door. The issue is the exposure, not whether a task appears to be “construction.”

Assess the fall route and likely consequences. A short fall onto sharp plant, a stair edge or a lower platform can be serious. A longer fall through fragile material may involve several hazards. Consider people underneath as well as the worker above. Falling tools or materials can injure someone even when the worker remains secure. If there is no work-at-height exposure, other workplace duties still apply.

Start by avoiding the height where reasonably practicable

Regulation 98 requires employers, taking account of the prevention principles, not to carry out work at height where it is reasonably practicable to do the work safely otherwise. Can an item be assembled at ground level and lifted into position? Can a fitting be lowered for maintenance? Can a long-handled tool achieve the result from a safe position? The decision needs to account for the risks of the alternative method too.

If height cannot reasonably be avoided, the employer must ensure the work can be done safely, prevent a fall liable to cause injury where possible, and then minimise the distance and consequences of a fall where prevention does not eliminate the risk. The HSA briefing explains the practical sequence: avoid, prevent, reduce. It favours collective measures such as safe platforms and guardrails before measures that protect only one worker or act after the fall begins.

The sequence is not a reason to ignore a practical higher-level control because a harness is available. It is also not a rule that one particular platform suits every job. Equipment choice must match the task, the duration, the surface, access and rescue needs.

Plan the task, supervision and emergency response

Regulation 95 requires work at height to be properly planned, appropriately supervised and carried out safely so far as reasonably practicable. Planning includes an appropriate risk assessment and safety statement under the 2005 Act, suitable equipment selection and preparation for emergencies and rescues. A short task still needs a proportionate plan.

Describe the actual location and activity. Who will do the work? How will they reach it and return? What does the surface support? Where could a person or object fall? What happens if weather changes, a machine moves or an access route is obstructed? What competence is needed for the selected equipment? A generic statement such as “wear PPE” does not answer these questions.

Supervision should match the risk and the experience of the workers. New or unfamiliar work may need closer oversight than a familiar task with stable controls. Record the condition that stops the job, such as damaged equipment, loss of edge protection, worsening weather or a change in the structure. Make sure the person at work can report the problem and is not pressured to continue on a method that no longer matches the assessment.

Plan rescue before work starts. A worker suspended in a fall-arrest system cannot be left with a plan that simply says “call emergency services.” Access, communication, suitable people and equipment depend on the location. This article cannot choose a rescue method for a specific roof or structure. The employer must establish a workable arrangement for the actual task.

Choose the work equipment that fits the job

Regulation 100 addresses selection of equipment for work at height. Where a compliant existing place of work or access route allows the task to be done safely, use it. Otherwise choose suitable equipment that prevents a fall where practicable. A stable working platform with guardrails can provide collective protection. A mobile elevating work platform may be appropriate for some access needs but creates its own ground, overturning and trapping hazards. Scaffold needs correct design, erection, inspection and use.

Ladders are not automatically forbidden. They are also not an automatic first choice because a task is quick. Part 4 sets conditions for ladder use; the assessment should consider whether safer equipment is justified given the risk and work characteristics. A worker carrying awkward materials may be unable to maintain safe contact. Repeated work or work needing two hands for long periods may call for a different platform. The HSA guidance on ladders should be checked alongside the current regulation rather than applying a blanket “ladders are fine under X minutes” rule.

Personal fall protection may be needed where collective measures cannot adequately control the risk. Its suitability depends on anchors, clearance, equipment compatibility, training and rescue. A clipped-on harness does not prevent a worker hitting an obstruction if there is insufficient fall distance. Do not infer that any anchor point is suitable because it looks strong.

Check surfaces, weather and falling objects

Regulation 96 requires visual checking of the surface and permanent protective measures before use and at appropriate intervals during use. Fragile rooflights and sheeting can be difficult to see. Plan access so a worker cannot step onto a fragile area or fall through it, using suitable barriers, platforms or other controls. A painted line or warning alone may be insufficient for the actual risk.

Regulation 97 addresses weather. Wind, rain, ice, heat or poor visibility can change what equipment and method remain safe. Plan how the team obtains a current weather picture and who stops the work. A method suitable in dry conditions may not remain suitable once surfaces become slippery or materials catch the wind.

Part 4 also addresses falling objects and danger areas. Secure tools and materials where needed, control the area below, and coordinate with other work. An exclusion zone should reflect what might fall and where it could travel, not merely the footprint beneath a platform. Check whether members of the public can enter. A sign may help communicate the boundary but does not replace physical controls where they are needed.

Check and maintain the equipment

Work equipment needs to be suitable and in safe condition. The specific inspection and maintenance obligations vary with equipment type and use. Do not assume a sticker alone proves a scaffold, platform or harness is safe for the present task. Look for damage, missing components, incompatible attachments and changes since the last inspection. Follow the applicable Part 4 requirements, manufacturer instructions and the site's competent assessment.

Keep relevant records available to people deciding whether the equipment can be used. An inspection should result in a defect being corrected or the equipment removed from service, not merely a completed form. Recheck after weather, impact, alteration or other event that could affect stability. A worker should know who to tell when a defect is found and what alternative method is available.

Example: roof equipment maintenance

A maintenance team needs to replace equipment near a roof edge. Before commissioning roof work, the employer checks whether the component can be serviced from below or lowered. If not, the assessment examines safe access, roof structure, fragile lights, edge protection, tools, weather, people below and rescue. The team chooses a method and equipment that prevent a fall where practicable. A supervisor verifies that protection remains in place and stops the job if the weather or structure differs from the plan.

That example is a decision sequence, not an instruction to use a particular ladder, platform or harness. A different roof or task may require a different engineered solution. Competent site-specific judgement remains essential.
