Emergency eyewash stations are essential safety measures in warehouse environments where employees may be exposed to hazardous substances. These stations provide immediate flushing of the eyes to minimize injury. Key requirements include:

• Accessibility: Eyewash stations should be easily accessible within 10 seconds of a hazard. The path to the station must be unobstructed and well-lit, located in normal traffic patterns, and on the same floor as the hazard.
• Location: Stations should be as close to the hazard as possible and identified with a highly visible sign using a symbol that is easily understood.
• Water Temperature: ANSI recommends that the flushing fluid should be tepid, defined as being between 16-38°C (60-100°F). Water that is too hot can enhance chemical interaction, while water that is too cold can cause hypothermia and inhibit workers from rinsing for the full recommended time.
• Flow Rate and Duration: Eyewash stations should deliver fluid to both eyes simultaneously at a flow rate of not less than 1.5 liters/minute (0.4 gallons/minute) for 15 minutes. Combination eye and face wash stations require 11.4 liters per minute (3.0 gallons per minute).
• Design: The unit should allow users to hold their eyelids open with their hands while their eyes are in the liquid stream. It should activate in less than 1 second and remain operational without requiring the operator's hand on the valve.
• Maintenance: Self-contained units should be installed and maintained according to the manufacturer's instructions. Regular inspections are needed to ensure the unit provides flushing liquid for at least 15 minutes and delivers tepid flushing fluid. Bladders must be replaced once activated or if expired.
• Emergency Procedures: Workers must know first-aid procedures appropriate to the hazards they are exposed to. [2] [2] [3] [1] [1] [1] [4]
