There is currently no specific Canadian standard for the design or placement of eyewash stations or emergency showers. The American National Standards Institute (ANSI) Standard Z358.1-2014 (R2020) "Emergency Eyewash and Shower Equipment" is generally used as a guide. Always follow the manufacturer's instructions for installing the unit. [2]

If a workplace has a hazard that could cause skin or eye injuries from a hazardous substance, the employer must provide eyewash stations for employees to use immediately. If this isn't feasible, the employer can provide portable equipment instead. If adverse weather conditions make both options unfeasible, the employer must provide personal protective equipment for all potentially exposed body parts. [3]

Here are some general guidelines for eyewash stations:

• Eyewash stations should deliver fluid to both eyes simultaneously at a flow rate of at least 1.5 litres/minute (0.4 gallons/minute) for 15 minutes.
• Combination eye and face wash stations need 11.4 litres per minute (3.0 gallons per minute).
• The unit should be 83.8 to 134.6 cm (33 to 53 inches) from the floor and at least 15.3 cm (6 inches) from the wall or nearest obstruction.
• The unit should be designed for activation in less than 1 second and remain operational without the operator's hand on the valve. [1] [1]

Employers must post specific information in a conspicuous place in each workplace, including:

• First aid procedures for injuries, occupational diseases, or illnesses.
• Locations of first aid stations, rooms, health units, and medical facilities.
• Lists of first aid attendants and how to find them.
• Emergency telephone numbers.
• Transport procedures for injured employees. [4]
