MAINTENANCE
SPECIFIC REQUIREMENTS
These units should be located as close to the hazard as possible
without physically causing a hazard itself, such as protruding
ttings. Emergency showers and eye/face washes shall be in
accessible locations that require no more than 10 seconds to
reach. Per ANSI Z358.1-2014, tepid water should also be used to
protect the user under frigid conditions, including provisions for the
proper disposal of the water. Installation procedures should be in
accordance with proper plumbing practices, with supply piping
sized adequately to meet ow requirements.
Supply lines should be properly ushed prior to installation of
emergency units.
EYE and EYE/FACE WASHES
All eye and eye/face washes should be connected with piping no
smaller than 1/2” IPS, and should be attached to a drain by a code
approved method to facilitate ease of testing.
Dynamic water pressure at the eye/face wash should be no less
than 30 psi or more than 90 psi during operation.
In areas where multiple eye injuries could occur simultaneously,
more than one eye/face wash is recommended.
EMERGENCY SHOWERS
Minimum pipe size to shower should be no smaller than 1” IPS.
Dynamic water pressure should be no less than 30 psi or more than
90 psi. On showers located more than 50 feet from the main water
supply, piping should be sized to provide friction losses no greater
than 50 feet of 1-1/4” pipe.
A drain should be provided for the shower.
In case of chemical burn, the victim should shower immediately
and a doctor or nurse should be notied.
COMBINATION SHOWERS and EYE/FACE WASHES
A drain should be provided for the shower, and the eye/face wash
should be connected to the drainage system.
Minimum pipe size to the combination unit should be no smaller
than 1-1/4” IPS. Dynamic water pressure should be no less than
30 psi during operation of both units. On units more than 50 feet
from the main water supply, piping should be sized to provide
friction losses no greater than 50 feet of 1-1/2” pipe.
The injured person should immediately turn on the shower and
remove all clothing as quickly as possible.
REGULAR TESTING
All emergency showers and eye/face washes should be tested
weekly. A testing tag is attached to each unit and is used to
record the date of the test and the initials of the tester. If there is
no oor drain available for proper testing of the shower, a Haws
Shower Test Kit, Model 9010, and container, Model 9009 should
be used.
