OPERATION & MAINTENANCE
1. Plumbed units shall be activated weekly to flush lines and verify proper flow pattern and volume.
2. If freeze or scald protection valve is included with your unit, the valves should be inspected each year, and cycled before hot
or cold weather sets in.
3. Test records should be maintained verifying compliance with testing procedures.
GENERAL INFORMATION
Following are requirements of ANSI Z358.1 for Emergency Eyewash and Shower Equipment. A complete copy of this standard
may be purchased from the International Safety Equipment Association.
1. Unit shall be installed in accordance with the manufacturer’s instructions and acceptable plumbing practices.
2. The height of the shower head shall be not less than 208.3 cm (82 inches) nor more than 243.8 cm (96 inches) from the
surface on which the user stands.
3. 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.
4. The unit shall be connected to a system capable of supplying adequate flushing fluid to meet the flow requirements of each
component operating simultaneously. The supply line shall provide an uninterruptible supply of potable water at a
recommended minimum 0.207 megapascal (30 pounds per square inch) of flow pressure.
5. Where the possibility of freezing conditions exists, equipment shall be protected from freezing or freeze-protected equipment
shall be installed.
6. When a shower 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 diameter of the spray pattern. It shall be a minimum of 50.8 cm (20
inches) at 152.4 cm (60 inches) above the standing surface. The center of the spray shall be at least 40.6 cm (16 inches)
from any obstructions.
7. When the eye/facewash 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.
NOTE: Test that all devices on combination units are capable of operating simultaneously to ANSI standard.
8. Shower units shall be in accessible locations that require no more than 10 seconds travel time from the farthest hazard.
9. Each unit location shall be identified with a highly visible sign. The area around the unit shall be well lit.
10. Plumbed units shall be inspected annually for proper operation to ensure compliance to ANSI Z358.1 standard.
TRAINING
All employees who might be exposed to hazardous material shall be instructed in the location and proper use of emergency
shower and eye/facewash units. Experiences have shown that initial first-aid treatment for irritates should be to wash the eyes
and face for 15 minutes prior to medical treatment. It is important to hold the eyelids open and roll the eyes so water will flow on
all surfaces and in the folds surrounding the eyes.
