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 
maintenance purposes.
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.
