Your ANSI Z358.1 Emergency Eyewash Station Inspection Checklist
A floor-ready checklist covering placement, weekly activation, annual servicing and recordkeeping for emergency eyewash and shower equipment. Built around ANSI Z358.1 thresholds and the OSHA clauses inspectors actually cite.
Every year, OSHA cites plants and labs under 29 CFR 1910.151(c) for emergency flushing equipment that is missing, blocked, or impossible to test. The remedy is rarely capital work — it is routine discipline. The ANSI Z358.1 emergency eyewash station inspection checklist below breaks the consensus standard into discrete checks, each with a pass criterion you can verify on the floor in minutes.
When This Checklist Applies
- ANSI/ISEA Z358.1 is the benchmark for emergency eyewash and shower equipment. The edition most facilities and auditors still work from is Z358.1-2014; a revision has been in progress at ISEA, so confirm which edition your client, insurer, or jurisdiction holds you to before updating forms.
- The standard is triggered by hazard, not headcount: where eyes or body may be exposed to corrosive materials, suitable flushing equipment must be within the work area for immediate use. OSHA enforces this through 1910.151(c) in general industry and 1926.50(g) in construction.
- Outside the US the same logic applies under different banners: provincial OHS regulations in Canada (Ontario's industrial-establishment rules, for example), the model WHS hazardous-chemicals code of practice in Australia, and COSHH emergency-procedure expectations enforced by HSE in Great Britain.
- A note for materials labs: Z358.1 is an ANSI/ISEA document, not an ASTM one, but any lab or pilot plant running corrosive-media testing — acids, caustics, etchants — inherits its requirements.
Placement and Access Checks (Z358.1 Section 3)
Run these once, then re-run them whenever layout, lighting, or chemical inventory changes:
- Travel time — a worker must reach the unit in 10 seconds or less, unobstructed, on the same level as the hazard. In practice that maps to roughly 55 ft (17 m), but the standard measures time, not distance.
- Door rule — if a door sits on the route, it must open in the direction of travel and require no key or special effort.
- Signage — a highly visible sign, readable from every direction of approach; most facilities use green with white lettering.
- Lighting — the unit and the path to it must be lit well enough to operate in an emergency.
- Tepid water — flushing fluid between 16 °C and 38 °C (60–100 °F). If you fitted a tempering valve, it needs the same weekly activation as the unit itself.
- No dead ends — never leave a tagged-out unit designated as the station of record.
Weekly Activation Checks (Sections 4, 5, 6 and 7)
This block is the core of any ANSI Z358.1 eyewash station weekly testing checklist. Activate every unit every week — plumbed or self-contained — and record it.
Plumbed eyewash (Section 4)
- Valve opens fully in 1 second or less and stays open hands-free.
- Flow is even and gentle, covers both eyes, and sustains at least 1.5 L/min (0.4 gpm) for a full 15 minutes.
- Nozzle caps lift automatically on activation; nozzles sit 33–45 in (84–114 cm) above the floor and at least 6 in (15 cm) from the wall or nearest obstruction.
- Water runs tepid and clear — flush stagnant supply lines until any discoloration is gone.
Plumbed shower (Section 5)
People searching for ANSI Z358.1 emergency shower requirements 2026 will find the thresholds unchanged: at least 75.7 L/min (20 gpm) for 15 minutes.
- Pulling the actuator delivers full flow in 1 second or less and stays open.
- Shower head mounted 82–96 in (208–244 cm) above the floor; actuator no higher than 69 in (175 cm).
- Drainage handles the full volume without flooding the approach path or nearby electrical equipment.
Combination units (Section 6)
- Shower and eyewash must deliver simultaneously — verify the supply piping was sized for the combined demand, a frequent design miss.
Self-contained units (Section 7)
- Fluid level correct or sealed cartridge in date; check the manufacturer's expiry marking.
- Activate weekly per the manufacturer's instructions and confirm the unit still sustains a 15-minute flush at 0.4 gpm.
- After testing, clean, refill or reseal, and return to service the same day.
- Personal squeeze bottles (Section 8) are support equipment only — they never substitute for a compliant station.
Annual Servicing and Records
- Annual full inspection — the maintenance clauses (Sections 4.5, 5.5, 6.5) require an annual inspection to the manufacturer's instructions: flow test, clean strainers and nozzles, verify the tempering valve, and reconfirm mounting heights after any plant changes.
- Records — log unit ID, date, inspector initials, result, and corrective action. When an inspector or insurer asks for proof of weekly activation, the completed ANSI Z358.1 emergency eyewash station inspection checklist and the logbook are the answer.
- Training — workers must be able to reach and operate the unit within seconds; brief every new hire and re-brief after process changes.
- An ANSI Z358.1 compliance checklist for facilities should finish by re-walking the placement checks: a new corrosive process on the far side of the plant means a new unit, not a longer walk.
Where the OSHA Citations Come From
OSHA has no dedicated eyewash-equipment standard, so enforcement lands on 1910.151(c) — and the failures repeat across citations:
- No unit within 10 seconds after a layout or process change.
- Path blocked by carts, totes, or closed doors.
- No tepid water — a cold-only line in an unheated area fails.
- No evidence of weekly activation or annual inspection.
- A dead unit left in place as the designated station.
When a unit goes down, tag it out and immediately provide an alternative compliant unit within 10 seconds of the hazard.
Takeaway
The whole standard compresses into three habits: place the equipment so a blinded worker can reach it in ten seconds, activate it every week and log it, and service it fully every year. Print this ANSI Z358.1 emergency eyewash station inspection checklist, laminate it at each unit, and the next audit becomes a five-minute walk instead of a citation.

Frequently asked questions
How often must an eyewash station be tested under ANSI Z358.1?
Plumbed eyewash, shower and combination units must be activated weekly (Sections 4.5, 5.5, 6.5) and receive a full annual inspection to the manufacturer's instructions. Self-contained units are checked weekly per the manufacturer's instructions, including fluid level and expiry.
What water temperature does ANSI Z358.1 require?
Tepid flushing fluid between 16 °C and 38 °C (60–100 °F). A cold-only supply in an unheated area does not pass, and any tempering valve needs the same weekly activation as the unit.
Does OSHA require ANSI Z358.1 compliance?
OSHA has no dedicated eyewash-equipment standard; it enforces 29 CFR 1910.151(c) in general industry and 1926.50(g) in construction. ANSI Z358.1 is the consensus benchmark inspectors and insurers use to judge whether flushing equipment is 'suitable.'
