Emergency and Eyewash Showers: What Does EN 15154 Require?
Emergency and eyewash showers rinse away chemicals within seconds and prevent lasting injury. This guide explains the requirements of EN 15154, the right location, flow rate and flushing time, plus the mandatory maintenance.

What does EN 15154 require?
The EN 15154 series sets out the requirements for safety showers. Parts 1 and 2 cover plumbed-in body and eyewash showers, Parts 3 and 4 the non-plumbed (tank-fed) versions. The key parameters are flow rate, water distribution and water temperature.
A body shower must deliver at least 76 l/min, an eyewash at least 6 l/min per eye. The water should flow evenly and gently so it does not injure the eye further. The valve opens with a single action and stays open on its own, leaving both hands free to hold the eyelids apart.
Where must the shower be located?
Location determines effectiveness. The shower must be immediately next to the hazard area and reachable within 10 seconds without obstacles, which corresponds to roughly 10 to 20 metres. The path should be straight, well lit and free of steps.
- Reachable within 10 seconds from the hazard, with no doors or steps in the way.
- Clearly marked with the ISO 7010 safety sign (E011/E012).
- Actuation without effort, operable even with the eyes closed.
- Free access, never blocked by shelving or equipment.
- Installed frost-free; outdoor units with trace heating.
Safety goggles, gloves and an apron complement the emergency shower in chemical areas.
Read the guideHow are emergency showers maintained?
Stagnant water in the supply line is a breeding ground for legionella and other germs. The standard and the manufacturer instructions therefore require a regular functional flush. Only a flushed, clear line delivers clean water instantly in an emergency.
- Document the weekly flush (date, tester, findings).
- Check the dust caps of the eye sprays for a firm fit.
- Test self-opening and self-holding of the valve.
- Replace damaged nozzles or scaled strainers immediately.
How do you rinse after a chemical accident?
After contact with acids, alkalis or solvents, every second counts. Bring the affected area under the shower immediately and rinse for at least 15 minutes, often considerably longer for alkalis. Remove contaminated clothing while rinsing.
- Open the eye wide and spread the lids apart with your fingers.
- Rinse from the nose outward so no chemical runs into the healthy eye.
- Remove contact lenses as early as possible.
- Always seek medical help after rinsing, even if things seem better.
Frequently asked questions
How long must you rinse with an emergency shower?
EN 15154 requires a flushing time of at least 15 minutes. For alkalis and strongly corrosive substances you should rinse considerably longer, until medical help arrives.
What water temperature is prescribed?
Tepid water between 15 and 37 °C is recommended. This makes the long flushing time tolerable and avoids cold shock or additional thermal injury.
How often must an emergency shower be flushed?
To prevent germs such as legionella, a weekly functional flush is recommended, complemented by a yearly check of flow rate and hardware by a specialist.
Is an eyewash enough or do you also need a body shower?
That depends on the risk assessment. Where larger amounts of chemicals can splash, a body emergency shower is also needed; for eye-only risks an eyewash often suffices.
