GENERAL RULES
Emergency equipment manufactured by Haws Corporation® is
warranted to function if installed per provided installation and
maintenance instructions. The units also must be used for the
purpose for which they were intended. This product is intended to
supplement rst-aid treatment. Due to widely varying conditions,
Haws Corporation cannot guarantee that the use of this emergency
equipment will prevent serious injury or the aggravation of existing
or prior injuries.
OSHA - Haws emergency equipment enables you to meet the
requirements in the OSHA Rules and Regulations covering this
type of equipment.
ANSI - Haws emergency equipment is manufactured to meet
ANSI Z358.1-2014 for Emergency Eyewash and Shower Equipment.
EMPLOYEE INSTRUCTION
To insure adequate operation of the units, all persons should
be instructed in the proper use of both the shower and eye/
face wash. Affected areas should be rinsed at the scene of the
accident for at least 15 minutes, and a doctor or industrial nurse
should be contacted immediately.
WARNING: Eye and eye/face wash units should not be used if it is
known that eye contamination is metal or some other rigid solid
fragment. In such an event, both the victim’s eyes should be gently
immobilized in accordance with the current “Red Cross Standard
First Aid Manual” and medical attention immediately sought.
IDENTIFICATION and SIGNAGE
Units should be installed in close proximity to hazardous areas,
free from obstructions that may inhibit immediate use, and clearly
identied as eye/face wash stations or emergency showers or both.
INSTALLATION AND WATER SUPPLY
Showers and eye/face washes should be connected to the main
potable water supply, and a loose-key lock-shield type stop or
shut-off valve is recommended to allow proper maintenance of
the unit. Valve must be labeled to prevent unauthorized shut-off.
One of the most important considerations when installing water
bearing emergency equipment is assuring an adequate supply of
water is available to unit. Piping should be installed no smaller than
the inlet size of the unit, and at least 30 psi dynamic pressure should
be available to the equipment. The ideal pressure for shower or
eyewash is between 30 and 90 psi.
Only products that meet the American National Standards Institute
(ANSI) for Emergency Eyewash and Shower Equipment (Z358.1)
should be installed.
INSTALLATION :: USAGE
Emergency eye/face wash, shower, drench hose, and
combination units are not a substitute for proper primary protective
devices. As a defense against ying solid particles and splashing
injurious liquids, workers should wear eye and face protectors and
protective clothing.
PROPER DRAINAGE
Appropriate drainage should be considered for emergency
showers and other equipment to prevent excess accumulation
of water on oors.
FREEZE-RESISTANCE
When installations are outside and temperatures drop below
32° F (0 ° C), freeze-proof units are recommended. Precautions
should also be taken to protect the user under frigid conditions. It
shall be the responsibility of each specifying authority to determine
the delivered water temperature that will be required in an area,
not only to provide the ow of water as required, but also maintain
it at a temperature that will be safe for the user. Delivered water
temperature should not be at extremes that might be expected to
discourage the unit’s effective use under emergency conditions.
The ANSI required range is 60° F - 100° F (15° C - 38° C). In
circumstances where chemical reaction is accelerated by water
temperature, a medical advisor should be consulted for the
optimum temperature for each application.
WARNING ALARM SYSTEMS
In remote areas or in hazardous locations where there are very few
people, a Haws Model 9001 alarm should be installed. This alarm
activates when a shower or an eye/face wash unit is used in order
to summon help to the injured.
PROTECTION FROM DEBRIS
Wherever possible, a Haws Model 9070 lter should be provided
upstream of the eye/face wash to remove particles from the water
and prevent additional eye damage. Model SP502 strainer tee is
also available.
Line size Y-strainer installed in supply line to unit should be
considered to reduce chance of debris reaching eye/face wash
and/or shower.
When protection of a Haws eye/face wash from dust or airborne
contaminants is necessary, Haws offers Model 9102 Dust Cover
which encloses the bowl and is available for selected
eye/face wash models.

SPECIFIC REQUIREMENTS
MAINTENANCE
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 notied.
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.
