(T-1) These bottles may be filled with potable water or an eye-flushing solution, either approved by the manufacturer or by the installation medical services. Local procedures shall be developed to prevent these units from being exposed to extreme temperatures. (T-1) Instructions and expiration dates shall be permanently affixed to the unit, if applicable. (T-1)

9.4. Location and Installation.

9.4.1. Location.

9.4.1.1. Eyewash and emergency showers shall be located as near to the hazard as possible with maximum of 10 seconds unobstructed travel distance from the source of exposure to the unit. (T-0)

9.4.1.2. Unobstructed means no objects, equipment, furniture or doors lie in the travel path. (T-1)
