Do eyewash station testing requirements have you confused?

Eyewash stations and emergency showers are critical safety assets designed to protect employees from chemical splashes, corrosive materials, and other hazardous exposures. But simply installing them isn’t enough—regular testing and inspection is required to ensure they work properly when an emergency occurs.

This guide explains how often eyewash stations should be tested, outlines the testing criteria for each required interval, and covers inspection differences for eyewash units, safety showers, combination units, drench hoses, sink-mounted systems, and portable eyewash stations.

Why Eyewash Station Testing Is So Important

When a chemical exposure occurs, seconds matter. An eyewash or safety shower that fails to deliver clean, flowing water at the proper rate can significantly increase the severity of an injury.

Routine testing helps ensure:

  • Water flows immediately when activated

  • No obstructions, sediment, or microbial growth are present

  • Valves and nozzles operate correctly

  • The unit complies with recognized safety standards

  • Documentation is available for audits and inspections

How Often Should Eyewash Stations Be Tested?

Eyewash and emergency shower testing typically follows three inspection intervals:

  • Weekly

  • Monthly

  • Annual

Each interval has different objectives and criteria. InspectNTrack inspection workflows are designed to align with ANSI Z358.1 eyewash and safety shower testing requirements. The following quick reference guide shows the eyewash station testing requirements for each type of eyewash or emergency shower unit.

Weekly Eyewash Station Testing Requirements

Purpose

Weekly testing verifies that the unit is operational and capable of delivering water immediately.

Testing Criteria (Weekly)

  • Activate the eyewash or shower to confirm immediate water flow

  • Ensure the valve stays open without requiring hand pressure

  • Flush the system long enough to clear stagnant water

  • Confirm spray heads are unobstructed

  • Check that protective caps are in place and function properly

  • Ensure access is unobstructed and signage is visible

Applies To

  • Plumbed eyewash stations

  • Sink-mounted eyewash units

  • Safety showers

  • Combination eyewash/shower units

  • Drench hoses

Monthly Eyewash Station Inspections

Purpose

Monthly inspections focus on condition, accessibility, and compliance readiness.

Testing Criteria (Monthly)

  • Verify weekly tests are being documented

  • Inspect for corrosion, leaks, or damage

  • Confirm proper mounting and stability

  • Ensure water pressure appears consistent

  • Verify temperature control devices (if present) function properly

  • Check that activation signage and instructions are legible

  • Confirm personal protective covers are intact

Applies To

  • All eyewash and emergency shower types

  • Portable eyewash units (with additional fluid checks)

Annual Eyewash & Safety Shower Testing Requirements

Purpose

Annual inspections confirm full compliance and verify that the unit meets all performance requirements.

Testing Criteria (Annual)

  • Measure flow rate and spray pattern

  • Verify correct spray height and coverage

  • Confirm continuous water flow duration capability

  • Validate temperature range where applicable

  • Inspect internal components and valves

  • Review inspection logs for completeness

  • Confirm compliance with applicable safety standards

Annual inspections are often performed by trained personnel or third-party inspectors.

Eyewash Station Testing Requirements by Equipment Type

Plumbed Eyewash Stations

  • Weekly activation required

  • Annual flow rate and pattern verification

  • Flush to prevent sediment and bacteria buildup

Sink-Mounted Eyewash Stations

  • Weekly activation to ensure diverter valves work properly

  • Confirm sink remains usable when eyewash is not engaged

  • Check spray heads for scale or blockage

Safety Showers

  • Weekly activation to confirm immediate flow

  • Ensure pull rods or handles are reachable and functional

  • Annual verification of flow volume and spray pattern

Combination Eyewash & Safety Shower Units

  • Weekly testing of both components

  • Confirm simultaneous operation if required

  • Annual verification of both eyewash and shower criteria

Drench Hoses

  • Weekly activation

  • Ensure flexible hose is intact and easily maneuverable

  • Confirm nozzle produces a controlled spray (not a focused stream)

Portable Eyewash Stations

  • Weekly visual checks

  • Fluid replacement based on manufacturer instructions

  • Verify expiration dates on preservative solutions

  • Ensure unit is properly pressurized (if applicable)

Documentation & Compliance

Accurate documentation is just as important as the inspection itself. Inspection records should include:

  • Date and time of test

  • Equipment ID or location

  • Inspection type (weekly, monthly, annual)

  • Inspector name

  • Pass/fail status and corrective actions

Digital inspection systems not only manage eyewash station inspection requirements, they also make it easier to maintain records, schedule recurring inspections, and demonstrate compliance during audits.

Final Thoughts

So, what are the actual eyewash station testing requirements?
At a minimum:

  • Weekly operational checks

  • Monthly condition inspections

  • Annual performance verification

Regular testing ensures your emergency equipment works when it’s needed most—protecting employees, reducing liability, and keeping your facility compliant.

If you manage multiple eyewash stations across one or more facilities, inspection software can dramatically reduce manual effort while improving consistency and documentation accuracy.
