1. Unit shall be installed in accordance with the manufacturer’s instructions and acceptable plumbing practices.
2. The eye/facewash shall be positioned with the water nozzles between 83.8 cm (33 inches) and 114.3 cm (45 inches) from the floor
and 15.3 cm (6 inches) minimum from the wall or nearest obstruction.
3. The unit shall be connected to a system capable of supplying adequate flushing fluid to meet the flow requirements of each
simultaneously. The supply line shall provide an uninterruptible supply of potable water at recommended
minimum 0.207 megapascal (30 pounds per square inch) of flow pressure.
4. Where the possibility of freezing conditions exists, equipment shall be protected from freezing or freeze-protected equipment shall be
5. When the unit is installed, it shall be tested in accordance with the following procedures:
a. With the unit correctly connected to the water source and the valve(s) closed, visually check the piping connection for leaks.
b. Open the valve to the full open position. The valve shall remain open without requiring further use of the operator’s hands.
c. With the valve in the “full on” position, measure the flushing fluid flow pattern with the use of a test gauge to determine a suitable
eyewash pattern as required by ANSI standards. Determine that both eyes can be irrigated simultaneously at a velocity low
enough not to be injurious to the user.
6. Eyewash units shall be in accessible locations that require no more than 10 seconds travel time from the farthest hazard.
7. Each unit location shall be identified with a highly visible sign. The area around the unit shall be well lit.
8. Plumbed units shall be inspected annually for proper operation to ensure compliance to ANSI Z358.1 standard.
