General Location

Emergency eyewash facilities and safety showers shall be in unobstructed and accessible locations that require no more than 10 seconds for the injured person to reach along an unobstructed pathway. If both eyewash and shower are needed, they shall be located so that each can be used at the same time by one person.


A travel distance of 55 feet in 10 seconds is cited by ANSI as the distance covered by an individual walking at a normal pace. Consideration should be given to the impaired abilities of the injured victim and the availability of others in the immediate area to assist. There should be no doors in the path of travel; however, if there are doors, there should be no more than one, and it shall swing in the direction of travel.

UC Practice

 

No obstructions, protrusions, or sharp objects shall be located within 16 inches from the center of the spray pattern of the emergency shower facility (i.e., a 32-inch clearance zone). Clear floor space requirements 48" x 30".

 

8 CCR 5162(c)

ANSI Z358.1 4.5.7 (3)

 

No electrical apparatus, telephones, thermostats, or power outlets should be located within 18 inches of either side of the emergency shower or emergency eyewash facility (i.e., a 36-inch clearance zone) or within any area that may be reasonably considered as a splash or flood zone. If 120-volt outlets or receptacles are present within 6 feet of an eyewash or shower, it shall be equipped with a Ground Fault Circuit Interrupter (GFCI).

 

UC Practice

NFPA 70 (NEC)

 

Personnel shall remove contaminated clothing while using a safety shower; if not, the corrosive/toxic material in the clothing will continue to act. Removing contaminated clothing without using a safety shower has caused skin burns after the original splashed chemical had been removed. Employees will resist removing contaminated clothing if they are in visible areas, so opaque modesty screens are needed. The screen can be stowed in a folded condition and deployed as needed, just like any shower curtain.
