First, does your facility or work area require an eyewash according to 29 Code of Federal Regulations (CFR) 1910.151(c)? It states “Where the eyes or body of any person may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing of the eyes and body shall be provided within the work area for immediate emergency use.” If so, then no, a 16 or 32 ounce bottle does not meet the standard. The key to meeting the standard, which defers to ANSI/ISEA Z358.1, is that the eye wash must deliver 0.4 gallons per minute (GPM) of tepid flushing fluid for 15 minutes to both eyes simultaneously. The ANSI/ISEA standard Z358.1 is a national consensus standard that OSHA refers employers to as a recognized source for guidance.
