How legionella bacteria grow in water systems, how people become ill and the checks that keep a building safe.
Legionella testing is the laboratory analysis of water samples for the bacteria. Cooling towers are sampled at least every three months. In hot and cold water systems, sampling is needed where control is in doubt, in healthcare and care settings and after a case of illness.

Straight answers about the legionella training course for Ireland learners: local acceptance, online delivery, certification and pricing at Online Safety Courses.
No. Legionnaires' disease is not contagious in the ordinary sense. It is caught by breathing in fine droplets of water that contain the bacteria, from a source such as a shower, a spa pool or a cooling tower. A person who has it is no risk to others.
Yes. Every employer and every person in control of premises must assess the risk from the water systems, however simple. For a small building with mains fed cold water and a small water heater the assessment is short, but it must still be done and reviewed.
Not normally. The bacteria cause disease when they reach the lungs, which happens by breathing in an aerosol. Drinking contaminated water is not a recognised route, except in the rare case where water goes down the wrong way into the lungs.
The legionella course runs beautifully on PC, laptop, tablet and smartphone, wherever in Ireland you happen to be. A clean, comfortable platform designed for smooth learning, at work, at home or on the move.

This legionella training course was designed around real working weeks: site rounds, tenant calls, maintenance windows and no spare afternoons. Every lesson streams on any device, every pause saves your place, and nothing needs installing. Real water systems and clear photographs turn the science of legionella, the five step risk assessment and the control measures into knowledge you can actually use the next time you walk your premises.
The syllabus tracks exactly what Irish law expects from every duty holder: understanding how Legionnaires' disease spreads, assessing the water systems you control, and running the temperatures, flushing routines and cleaning schedules that keep people safe.
Whether you need your own certificate for a new role or you are certifying a whole facilities team, the legionella training flows without friction from registration to certificate.
A classroom legionella course means lost working hours, travel and cover costs, often across several staff at once. The online legionella course removes all of it. Staff certify from home or the workplace, at their own pace, starting the moment you enrol them.
Managers see each completion in real time and can show an auditor the complete training record in seconds. Stack the automatic volume discounts on top and this becomes the most economical accredited legionella training available in Ireland.
Pricing is honest: one figure covers the full course, unlimited retakes and the instant legionella training certificate. No add ons, ever.
Rosters and busy weeks leave no room for fixed course dates. The self paced legionella course lets you move at whatever speed suits, pausing on any device and resuming exactly where you left off, before work, at lunch or on the commute.
A clear progress tracker shows how much of the legionella training remains and how close the certificate is. Some learners finish in one focused sitting; others spread it across a few breaks. Both work perfectly.
Assign it to your team and they will slot it around their schedules without disrupting the work, one of the main reasons Irish employers return to Online Safety Courses year after year.
There is no waiting around. Pass the assessment and the digital legionella training certificate is generated on the spot, aligned with Irish legislation and recognised across Ireland, the UK and Europe.
It lives permanently in your account for re-download during audits, insurance renewals, tenancy handovers and job applications, and its unique verification code lets anyone confirm it instantly.
For duty holders, every certificate is dated proof that the people running your water systems are trained and competent, exactly what matters if an inspector or an insurer ever asks.
Every module comes from licensed, Chartered (CMIOSH) consultants working with current Irish health and safety law and Health and Safety Authority guidance.
That experience shows: the science of legionella explained through recognisable water systems, the risk assessment taught with the situations duty holders actually meet, from old calorifiers to vacant properties, and the control measures presented the way they actually work on an Irish premises, never as abstract theory. Practical judgement runs through every lesson.
Content is re-reviewed against current legislation and the Code of Practice for the Prevention and Control of Legionellosis, so the course never drifts out of date.
The platform never closes, which matters when the work never really does either. Start the legionella training after a shift, continue at lunch the next day and finish on a day off, whatever rhythm your week allows.
Progress syncs across every device automatically, so switching from phone to laptop mid module is seamless. Night staff, part timers and weekend crews get exactly the same premium experience.
Teams can also reopen the risk assessment module before an audit or the control measures module when a system changes, turning the legionella course into a living reference rather than a one time event.
Online Safety Courses has certified more than 749,500 learners across Ireland, the UK and Europe, with a 98% pass rate and a 4.9 star average from verified Google reviews we cannot edit or hide.
From Dublin to Cork, Galway to Limerick and Waterford to Belfast, our legionella training helps Irish premises stay compliant and keeps the people who use them safe from Legionnaires' disease.
Employers come back because it simply works: clean records, instant certificates and a support team that answers.
Every organisation and person in control of premises with water systems, because the law places the duty squarely on whoever controls the risk. Under the Safety, Health and Welfare at Work Act 2005 and the Chemical Agents Regulations 2001, duty holders must assess and control hazards such as legionella, and the Code of Practice for the Prevention and Control of Legionellosis names trained, competent people as the way it is done. Waiting until someone falls ill is the one strategy the law does not forgive.
In practice, the people taking this course with us are facilities and maintenance managers, landlords and letting agents, hotel and leisure teams with spa pools and showers, care home and school managers, gym owners, and the employers and building owners responsible for them.
If your premises has water systems that people use or that can release water droplets into the air, this training is for you, and our Irish support team can help roll it out across every location.
How legionella bacteria grow in water systems, how people become ill and the checks that keep a building safe.
Testing means sending water samples to an accredited laboratory to be cultured, with results reported as colony forming units per litre. It shows whether the controls are working. It does not replace them.
A positive result triggers a review of the controls, resampling and, depending on the count, cleaning and disinfection of the system.
Records show that the system is under control and are the first thing asked for after a case of illness. They are kept for at least five years.
Temperature control is the main defence in ordinary hot and cold water systems. Hot water is stored at 60°C or above and reaches at least 50°C at the outlets within one minute of running, or 55°C in healthcare premises. Cold water is stored and delivered below 20°C, within two minutes of running. Where water this hot could scald, thermostatic mixing valves are fitted close to the outlet.
The bacteria need four things: water between 20°C and 45°C, stagnation, nutrients such as scale, rust, sludge and biofilm, and a way of forming an aerosol. A system that offers all four is a risk. Removing any one of them reduces it.
People are infected by inhaling fine droplets of contaminated water.
The bacteria multiply in lukewarm, stagnant water with scale, rust or slime to feed on.
Keep hot water hot, cold water cold and all of it flowing.
The accredited Legionella Course covers where legionella grows, how people are infected and how water systems are kept safe, in about an hour online, with a CPD certified certificate the moment you pass.
