How do Eyewash Stations work?
An eyewash station delivers two soft, aerated streams of tepid water that bathe the eyes so chemicals are diluted and rinsed away without driving them further into the eye. Water flows at about 1.5–2 L/min per eye at low pressure, and the heads are positioned so the user holds the eyelids open in the flow. Stay-open valves allow both hands to be used, and most units provide at least 15 minutes of flushing. Some stations add a face and body spray, and drench hoses reach areas that fixed heads cannot. Units are placed within 10 seconds of hazards, on the same level, with a clear approach and clear signage. Weekly activation flushes stagnant water, and annual inspection verifies flow, temperature, height and spray pattern against ANSI/ISEA Z358.1 or EN 15154-2.
Which Eyewash Stations variants are available?
- Wall-Mounted Eyewash Station — A wall-mounted eyewash station fixes two aerated heads to a wall or panel near the hazard.
- Pedestal Eyewash Station — A pedestal eyewash station stands on the floor where no suitable wall is available.
- Deck-Mounted Eyewash Unit — A deck-mounted eyewash unit fits onto a sink or bench and uses the existing water supply.
- Drench Hose Eyewash Unit — A drench hose eyewash unit is a flexible hose with an aerated head that can be directed at the eyes, face or body.
- Portable Gravity-Fed Eyewash Station — A portable gravity-fed eyewash station supplies flushing water without a plumbed connection.
How do I choose the right variant?
Choose wall-mounted units for general laboratories where a wall is available near the hazard, and pedestal units where there is no suitable wall or the floor space is free. Deck-mounted eyewashes fit onto a sink and save space but must still be within 10 seconds of the hazard. Drench hoses are used where the risk is localised, such as a specific transfer point, but they need a user who can hold the hose. Portable gravity-fed units suit field work, temporary installations or locations without a plumbed supply, though they have limited capacity. Confirm flow, tepid temperature, spray height and coverage, and that the approach is unobstructed. Verify that the unit suits the chemicals used, and provide signage and training.
Where are Eyewash Stations used?
Eyewash Stations are specified in chemical and reagent handling, histology and staining areas, battery and electrolyte work, pharmaceutical and QC laboratories, teaching laboratories and field and temporary sites.
Which standards and certifications apply?
Work with Eyewash Stations is commonly governed by ANSI/ISEA Z358.1 (emergency eyewash and shower equipment), EN 15154-2 (eyewash for laboratories), EN 15154-1 (body showers for laboratories), GB/T 38144 (emergency shower and eyewash), ISO 3864 (safety signage) and DIN 12926 (laboratory eyewash). Instrument certifications such as CE marking are confirmed per configuration and never assumed.
What are the key considerations before purchase?
Perform a hazard assessment to confirm each station is reachable within 10 seconds, on the same level, and not blocked by equipment, doors or stored items. Activate every unit weekly to flush the line and confirm the valve stays open, and inspect annually for flow, temperature, spray pattern and head height. Maintain tepid water in the range of about 16–38 °C, since cold water discourages the required 15 minutes of flushing. Clean the heads and check for biofilm growth in stagnant lines, especially where use is rare. Provide clear signage, train staff on flushing technique including keeping the eyes open, and record all checks and maintenance for audit.
