In warehouse environments where chemical exposure is a risk, it's crucial to have emergency eyewash stations available. While specific requirements may vary based on local occupational health and safety regulations, the ANSI Z358.1-2014 (R2020) standard, "Emergency Eyewash and Shower Equipment," is often used as a guide for the design and placement of this equipment. [4]

Key safety requirements and recommendations include:

• Accessibility: Eyewash stations should be located as close to the hazard as possible, reachable within 10 seconds, and on an unobstructed path. The location must be identified with a highly visible sign. [3] [3] [3]

• Water Temperature: The ANSI standard recommends that the flushing fluid be tepid, defined as between 16-38°C (60-100°F). Anti-scalding devices should be installed to maintain a constant temperature. [1] [1]

• Flow Rate and Duration: Eyewash stations should deliver fluid to both eyes simultaneously at a minimum flow rate of 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). [5]

• Design and Functionality: The unit should be between 83.8 and 134.6 cm (33 to 53 inches) from the floor and a minimum of 15.3 cm (6 inches) from the wall or nearest obstruction. It should activate in less than 1 second and remain operational without requiring the operator's hand on the valve. [5] [5]

• Maintenance and Inspection: Eyewash stations, including personal eyewash equipment, should be inspected and activated weekly, with a complete inspection at least annually. A signed, dated record of these inspections should be maintained. [6] [6] [6] [6]

• Flushing Fluid Quality: The flushing fluid should be potable water, preserved water, preserved buffered saline solution, or other medically acceptable solutions. Self-contained systems should be frequently checked and cleaned to prevent contamination. [4] [2]

• Training: All workers should be trained in the proper use and location of eyewash stations before any emergencies occur. Written instructions should be available and posted beside the equipment. [6] [6]

Adhering to these guidelines helps ensure that warehouse environments are equipped to handle chemical exposures effectively, protecting worker safety and ensuring compliance with regulatory requirements.
