lone worker risk assessment Ireland emergency plan

Direct answer. Working alone is not generally prohibited in Ireland, but an employer must assess whether the worker faces significantly greater risk without close or direct supervision. If the task cannot be done safely by one person, arrange help, backup or a different way of working. A useful assessment covers the job, place, worker, travel, communication, foreseeable emergency and a real response plan when a check-in fails. A phone number alone does not establish that someone will notice and act in time. HSA lone-workers guidance; Safety, Health and Welfare at Work Act 2005.

This is a Republic of Ireland task decision and emergency-planning guide, not a generic software page. The existing Irish risk-assessment software page owns the broad commercial query. UK-specific HSE lone-working guidance may be useful for comparison, but it is not the authority for Irish duties. Sector rules may impose additional supervision restrictions, so check the actual activity before approving lone work.

Identify where the worker is truly alone

“Lone worker” can include a cleaner arriving before others, a maintenance technician on a remote site, a healthcare worker visiting a home, a retail employee closing a shop, a driver, or a worker in a large building whose colleagues cannot see or hear them. Ask whether immediate help is available in the actual shift and location, not merely whether other employees are on the payroll. A person may work beside a colleague for most of the day but be effectively alone during opening, travel, a confined maintenance task or late close.

Map the lone period, task, location, travel route, communication coverage and people who could provide help. Include contractors and visiting workers: the host employer should pass on relevant workplace hazards and controls, while the worker's own employer must assess the task and coordinate arrangements. The HSA specifically points to cooperation where a lone worker attends another employer's workplace. HSA lone-workers guidance.

Avoid a single company-wide score called “lone working: low risk.” Risk changes with the work. Routine stock counting in an accessible building differs from electrical fault-finding, operating dangerous machinery, handling hazardous substances, confronting a potentially violent person or travelling to an isolated property after dark. A competent assessment should distinguish normal work from the foreseeable abnormal case.

Ask the stop question first

Can the risks of this job be adequately controlled by one person? If the answer is no, do not solve the problem by writing a more elaborate check-in schedule. Reorganise the task, provide a second person, move the work to a staffed time, use remote isolation, or stop until suitable help is available. The HSA says backup or help must be arranged when the assessment finds the work cannot safely be done by a lone worker. HSA lone-workers guidance.

Examples of tasks that may need a second person or specific supervision include activities requiring two-person handling, rescue capability, control of aggressive interactions, or technical emergency assistance. The precise decision depends on the equipment, site, competence and any industry-specific law; there is no universal list that turns every task into an automatic prohibition. State the decision and the evidence used, including what the worker must do if conditions exceed the assessed limits.

Example. A facilities technician can replace a low-risk filter during normal hours with reliable communication and local help. The same technician should not infer approval to investigate an energized electrical fault alone overnight. The hazards, isolation, competence, rescue and response time differ; perform a separate task assessment and use a competent electrical procedure.

Assess the person, place and foreseeable emergency

List the task hazards and who could be harmed. Consider falls, machinery, substances, vehicles, manual handling, fire, sudden illness, violence, weather and loss of communications. The HSA asks whether access and exit can be managed by one person, whether plant and goods can be handled safely, whether violence is possible, and whether the person is competent and suitable for the work. Medical suitability should be handled sensitively and with appropriate professional advice rather than an intrusive generic declaration. HSA lone-workers guidance.

The location matters. Record whether the worker has mobile coverage or a radio signal, can give emergency services an accurate location, has safe access, lighting, welfare and first-aid arrangements, and can travel home safely. In remote settings, ask how long the work should take and when a missed report should trigger action. Check whether an alarm can actually transmit from the room or basement where the task occurs. A successful test at the office is not evidence of signal on a remote site.

Ask workers and supervisors what really happens when the normal contact is unavailable. If the only supervisor routinely finishes before the lone shift, the escalation chain is fictional. If a security gate locks after hours, emergency responders need a realistic access plan. Test the worst credible delay, not the best-case response.

Build a check-in and escalation plan

Choose a check-in interval based on risk, expected task duration and communication reliability. The plan should identify the worker, task, location, expected start and finish, agreed contact method, responsible monitor, missed-check trigger, backup contact and emergency service escalation. Set an explicit timeline: who calls the worker, when the backup is contacted, and when someone travels to or contacts emergency services for the site. HSA guidance lists periodic checks, communication devices, automatic warning devices, training and emergency arrangements as possible measures, selected through risk assessment. HSA lone-workers guidance.

For a lower-risk inspection in a staffed building, a start-and-finish confirmation may be proportionate. For a remote task with greater harm potential, checks may need to be more frequent and a separate alarm or second person may be justified. Do not publish a universal 15-minute rule; the correct interval follows the particular risk and response time. The worker and monitor need to know what a missed check means, including what to do if the phone is lost, battery is flat or network is down.

A useful test is to simulate the missed check. Did the assigned person notice? Could they find the worker's exact location? Did a backup answer? Could someone access the site? If not, revise the plan. A dashboard that records “no check-in” but alerts nobody who is available is a record of failure, not an emergency control.

Train for decisions, not just a device

Workers should know the task limits, hazard controls, check-in method, code words or alarms where appropriate, and when to stop work. Monitors must know their response duty and who takes over at shift change. Provide enough competence for foreseeable unusual conditions, not just routine steps. The HSA stresses that lone workers should not be left to decide alone whether they need assistance with work beyond their training. HSA lone-workers guidance.

Where violence is a risk, include de-escalation and a safe withdrawal route. Where a sudden illness is credible, consider access to help and first aid. Where the worker visits a third-party site, coordinate hazard information with the host and keep an accurate address. Rehearse the arrangements in a way that respects privacy and dignity; safety monitoring is not a licence for unnecessary surveillance.

Keep the assessment current

Review after a changed task, site, shift, staffing arrangement, communication method, incident, near miss or failed drill. New mobile coverage can improve a plan, but a new building layout or locked gate can defeat it. Record who reviewed the decision and what changed. Include workers' experience: they are often first to know that the apparent “lone period” lasts longer than the schedule suggests.

A minimal record should identify the assessed task, lone period, significant hazards, why one-person work is or is not acceptable, controls, contact and escalation method, emergency access, competence, owner and review triggers. Attach site-specific details that the response person actually needs. Avoid placing sensitive medical information in an ordinary risk register; record only the control decision and handle personal data through suitable processes.

Common mistakes

  • Assuming lone work is safe because no incident has occurred.
  • Assessing the daytime task while ignoring opening, closing, travel or night work.
  • Using check-ins to justify a task that needs a second person or rescue capability.
  • Choosing intervals without testing response time and location access.
  • Making a manager responsible for missed checks when that manager is off duty.
  • Relying on mobile coverage that has never been tested at the work point.
  • Leaving the worker to improvise when a task changes or a control fails.

Where Complys fits

The Irish risk-assessment software page is the relevant commercial owner for evaluating record and action management. This guide does not claim Complys provides live lone-worker monitoring, GPS tracking, automated missed-check escalation, emergency dispatch or rescue. For the next step, pick one real lone-working shift, decide whether that job can safely be done alone, and test the missed-check response with the people named in the plan.
