Lone working legislation in Ireland comes down to a single test, and it is not the one most people expect. No Irish law prohibits working alone, and no Irish law mentions lone workers by name. What decides whether your employee may work alone is the risk assessment under section 19 of the Safety, Health and Welfare at Work Act 2005, and that turns out to be a stronger mechanism than it sounds.
Yes. The Health and Safety Authority puts it plainly on its lone workers guidance: “There is nothing specific in general legislation that prohibits a person from working alone.”
The sentence that matters comes next. The HSA’s position is that section 19 requires the employer to undertake a risk assessment, and that this assessment “shall determine whether or not an employee may work alone”. So the law does not answer the question for you. It hands you the question, and your own assessment becomes the ruling: for this role, in this place, with these controls, alone is either acceptable or it is not.
That is a stronger formulation than it first appears. It means “we’ve always done it this way” is not a position, and it means the answer can change when the circumstances do. It also means the assessment has to be honest enough to sometimes say no.
Section 19(1) of the 2005 Act sets the duty:
“Every employer shall identify the hazards in the place of work under his or her control, assess the risks presented by those hazards and be in possession of a written assessment (to be known and referred to in this Act as a ‘risk assessment’) of the risks to the safety, health and welfare at work of his or her employees.”
Two words in there deserve more attention than they get. “Every employer”: there is no employee-count threshold anywhere in section 19, so a two-person operation owes the same duty as a two-hundred-person one. And “written”: the assessment has to be in writing, and that is section 19’s own requirement rather than good practice. There is no size threshold on that either.
Section 19(3) then keeps the assessment alive. It must be reviewed where “there has been a significant change in the matters to which it relates” or “there is another reason to believe that it is no longer valid”. A round of evening appointments added to a care rota, a depot that starts opening on weekends, an incident that nearly went wrong: each is the statute telling you to look again.
There is a third piece worth knowing. Under section 19(5), the duty can extend beyond your own staff, “to the extent that” an employer’s duties “may apply to persons other than his or her employees”. Contractors and self-employed people working alone on your behalf are not outside the frame, and the HSA’s guidance counts them as lone workers in exactly the same way.
Our guide to lone working risk assessments covers how to build the assessment itself.
This is the part of Irish law with no direct equivalent elsewhere, and the part most likely to be missing from a policy written outside Ireland.
Section 20 requires every employer to prepare a written safety statement, “based on the identification of the hazards and the risk assessment carried out under section 19”. The two sections are deliberately chained: the assessment finds the risks, the statement says what you are doing about them. It must set out the protective measures and resources, emergency procedures, the cooperation expected of employees, and the names and job titles of the people responsible.
For lone workers, that last requirement is quietly the most useful one. A named person, by job title, is responsible for the arrangements that protect someone working alone. When an alarm goes off at 9pm on a winter night, the safety statement is where it should already be written down whose job it is to respond.
One relief exists for the smallest employers. Under section 20(8), an employer with three or fewer employees can satisfy this section by observing a relevant code of practice, where one exists. Be careful with the scope of that: it relieves the safety statement obligation, not section 19. A three-person firm still owes the written risk assessment in full.
The HSA describes lone workers as “those who work by themselves without close or direct supervision”, and it is explicit that the category includes contractors and the self-employed. Two further points from its guidance shape what a defensible arrangement looks like.
Responsibility stays put. In the HSA’s words, an employer’s responsibilities “cannot be transferred to any other person, including those who work alone”. A worker who is content to work alone, or who signs something saying so, has not taken the duty off you.
Controls are expected, not optional extras. The HSA points to communication devices, warning systems, training and emergency procedures as the kinds of measures an assessment should prescribe. For anyone employing lone workers in health or social care, the Authority publishes dedicated guidance on managing the risk of lone working in that sector, and our own piece on lone working in social care covers the operational side.
Plenty of organisations run teams on both sides of the border, and this is where a UK policy applied unchanged to Irish operations goes wrong. Four differences carry most of the weight.
The regulator is the Health and Safety Authority, not the HSE. Citing HSE guidance in an Irish policy document is the quickest way to signal it was written for somewhere else.
The written requirement has no threshold. In the UK, the duty to record a risk assessment applies at five or more employees. Section 19 requires a written assessment from every employer, full stop.
The safety statement is Irish law only. There is no UK document that does its job, so a transplanted UK policy will simply not have one.
RIDDOR does not apply. It is British legislation, and Irish incident reporting runs under Irish rules. A policy that tells Irish staff to make RIDDOR reports is incorrect.
The two systems look alike, and that is exactly why the differences slip past. Irish law is its own law, and a policy has to be built for it rather than borrowed from across the border.
Run the test the statute sets, honestly. For each role, the section 19 assessment decides whether working alone is acceptable, and with what controls. Where the answer is yes-with-controls, three things tend to decide whether the arrangement works in practice.
Communication that survives the places people actually work. A phone with one bar in a farmyard in Leitrim does not count as communication in any sense that helps. Safepoint’s lone worker device runs on a multi-network roaming SIM over 4G LTE and WiFi, and the app integrates what3words, which was built for exactly the kind of unnamed rural locations where an eircode covers half a townland. Location Beacons handle the indoor dead-zones GPS cannot reach.
A named responder who can actually respond. The safety statement wants names and job titles against responsibilities. In Safepoint that named person is the guardian: the alert reaches them on their own phone, with the worker’s live location, so they can act on it wherever they are. Nobody has to be sitting at a desk watching a screen, which matters because in most small Irish organisations nobody is.
A record that matches reality. Section 19(3) expects the assessment to be reviewed when circumstances change, and the honest way to know they have changed is a record of what lone shifts actually look like: tasks, routes, alerts and how each one was resolved. Safepoint’s management portal keeps that history as a matter of course, so each review starts from what actually happened rather than what anyone remembers. None of this, on its own, makes an employer compliant: the assessment, the statement, the training and the follow-through are yours, and a tool is one control among several. If you are weighing up equipment options more broadly, our roundup of the best lone worker devices and solutions is the place to start.
Read your own risk assessment and ask whether it genuinely answers the question section 19 exists to make you answer: can this employee work alone safely, and with what controls? If it does not answer that, for each lone working role, it is not yet doing what section 19 asks of it.
Both sources are short and worth the time. Section 19 runs to half a page in the Law Reform Commission’s revised text, and the HSA’s lone workers guidance is the regulator’s own answer to most of the questions on this page.
