Emergency showers and eyewash stations are there for the worst day, and hopefully they are rarely used. That is exactly the problem: water that sits unused in the connecting pipework can stagnate, warm up and give legionella bacteria the conditions they like.
Why they matter for legionella
- They are classic little-used outlets, sometimes unused for months.
- Water in the supply pipe can stand still between tests.
- When used, they can produce a spray that people may breathe in, as well as washing the eyes and skin.
- They are often in labs, workshops, kitchens, food sites and plant rooms, where nobody thinks of them as part of the water system.
Good practice
- Put them on your risk assessment. If a unit is not listed, it is not being managed.
- Flush regularly. Typically, units are activated for a short period on a set routine, often weekly, and the flushing is recorded. Your risk assessment should set the frequency for your site.
- Follow the manufacturer’s guidance on testing and maintenance, including any cartridges or self-contained units that need refilling or changing.
- Keep the area clear so people can reach the unit quickly in an emergency.
- Record every check in your logbook. See our guide on the legionella logbook.
- Look for dead legs where a unit has been moved or removed. Our guide on dead legs and little-used outlets explains more.
Your duties
Under the Safety, Health and Welfare at Work Act 2005, employers must manage risks to the health of employees and others affected by their activities, which includes risks from water systems. The HPSC National Guidelines for the Control of Legionellosis in Ireland (2009) give practical guidance.
Not sure where to start?
A site visit usually turns up outlets people had forgotten were there.
