MAINTENANCE INSRUCTIONS
Step 1: Self contained eyewash equipment shall be visually checked to determine if
flushing fluid needs to be changed or supplemented.
Frequency of inspection : Depending on evironmental conditions, visual inspections
should be performed on either a daily, weekly or monthly basis as somme water loss
will occur due to natural evaporation process.
Step 2: Take proper precautions to help prevent the growth of potentially harmul
bacteria in eyewash tanks.We recommend either of the following procedures:
A. Use suitable Bacteriostatic Preservative to help prevent the growth of bacteria in
eyewash tank.Eyewash tank should be drained,flushed and refilled with clean
potable water and Bacteriostatic Preservative as drected by the preservative`s
manufacturer.
B. Drain,flush and refill portable units with clean potable water at least once every
week.Thoroughly cleanse tank at least once every month.
NOTE: Acanthamoeba survive mild chlorination and are commonly found in tap water.
Bacteriostatic Preservative will prevent the growth of Acanthamoeba.Hot water,
70° C (158° F) or hotter will destroy Acanthamoeba but must be allowed to cool
prior to use in eyewash units.
