The ANSI standard says that “nozzles and flushing fluid units must be protected from airborne contaminants. Whatever means is used to afford such protections, its removal shall not require a separate motion by the operators when activating the unit.” Covers cannot be used unless they are specifically designed by and installed to the eyewash manufacturer’s specifications (e.g., nozzle covers). In other words, a plastic bag, bucket, shower cap, etc. cannot be placed over the nozzles of an eyewash if it would require a motion to remove before the eyewash could be activated. Remember, a user’s hands need to be free to aid in proper flushing or the removal of clothing.
