OSHA was asked whether it requires a minimum volume of portable eyewash solution in areas where workers face eye hazards from spit or splatter containing blood or other potentially infectious materials (OPIM).
OSHA clarified that the Bloodborne Pathogens standard (29 CFR 1910.1030) does not specify a minimum eyewash volume, but the regulatory intent requires that 'blood or OPIM be removed from the eyes' — so 'sufficient water must be used to accomplish this goal.' Citing ANSI Z358.1 guidance, OSHA stated that eyewash facilities should deliver flushing fluid at 'not less than 1.5 liters per minute (0.4 gpm), for fifteen minutes.'
By that measure, OSHA concluded that four-ounce bottles are insufficient. When proper eyewash facilities are unavailable, 'a one-liter bag of saline or ringers lactate may be more appropriate' as an interim measure until the worker can access a facility with full 15-minute flushing capability.
The letter also reminded employers that the Bloodborne Pathogens standard requires post-exposure procedures, including medical evaluation, documentation, testing, prophylaxis, and counseling (29 CFR 1910.1030(d)(2)(vi), 1910.1030(d)(3)(x)).
