Emergency Eyewash Equipment
This standard establishes minimum performance and use requirements for eyewash equipment for the emergency
treatment of the eyes of a person who has been exposed to injurious materials.
Only plumbed eyewash equipment is offered in this facility.
Plumbed Eyewash Equipment: A controlled
flow of flushing fluid, in a volume no less than 1.5 liters
per minute (0.4 gpm) for 15 minutes, is provided to both eyes
simultaneously at a velocity low enough to be non-injurious
to the user, from an eyewash unit designed and positioned in
such a way as to pose no hazards to the user.
The surface of the nozzle delivering the flushing fluid will
be protected from airborne contaminants. Removal of such
protection shall not require a separate motion when
activating the unit.
Plumbed and self-contained units shall be constructed of
materials that will not corrode in the presence of the
flushing fluid. Stored flushing fluid shall be protected
against airborne contaminants.
The valve shall be designed so that the flow remains on
without requiring the use of the operator's hands. The valve
shall be designed to remain activated until intentionally
shut off. The valve shall be simple to operate and shall go
from 'off' to 'on' in 1 second or less. The valve actuator
shall be large enough to be easily located and operated by
the user. Provision is made to prevent unauthorized shut off
when shut off valves are installed in the supply line for
Eyewash units shall be physically located in accessible
locations that require no more than 10 seconds to reach. The
eyewash unit shall be located on the same level as the hazard
and the path of travel shall be free of obstructions that may
inhibit the immediate use of the equipment. For a strong
acid or strong caustic, the eyewash should be immediately
adjacent to the hazard. It is recommended that the
consulting physician or appropriate professional be contacted
for advice on the proper distance.
Each eyewash location shall be identified with a highly
visible sign positioned so the sign shall be visible within
the area served by the eyewash. The area around the eyewash
shall be well-lighted.
Delivered flushing fluid temperature shall be tepid. In
circumstances where chemical reaction is accelerated by
flushing fluid temperature, a medical advisor should be
consulted for the optimum temperature for each application.
Continuous and timely irrigation of affected tissues for the
recommended irrigation period are the principal factors in
providing first aid treatment. Providing flushing fluid at
temperatures conducive to use for the recommended irrigation
period is considered an integral part of providing suitable
facilities. Medical recommendations suggest a flushing fluid
at tepid temperatures be delivered to affected tissue.
Temperatures in excess of 38 C (100 F) have proven to be
harmful to the eyes and can enhance chemical interaction with
the eyes and skin. While cold flushing fluid temperatures
provide immediate cooling after chemical contact, prolonged
exposure to cold fluids affect the ability to maintain
adequate body temperature and can result in the premature
cessation of first aid treatment.
Employees who may be exposed to hazardous materials shall be
instructed in the location and proper use of emergency
eyewash units. When addressing washing of the eyes, training
shall address holding the eyelids open and rolling the
eyeballs so flushing fluid will flow on all surfaces of the
eyes and under the eyelid.
