Under OSHA’s general-industry rule, employers must provide suitable facilities for quick drenching or flushing of the eyes and body when a worker may be exposed to injurious corrosive materials. The facilities must be within the work area for immediate emergency use. The regulation does not set a universal distance, flow rate, or equipment design.
When does OSHA require an emergency eyewash or shower?
The general-industry requirement is in 29 CFR 1910.151(c): “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.” Paragraph (c) was published at 63 FR 33450 on June 18, 1998.
The trigger is a potential exposure to injurious corrosive materials—not simply the presence of any chemical. Employers need to assess the substances, tasks, and ways a worker could be exposed, then determine what facilities are suitable for an immediate emergency response. The rule does not prescribe one device for every workplace.
Additional OSHA requirements can apply to specific operations. OSHA identifies provisions for certain HIV/HBV research laboratories and production facilities, and for potential eye splashes of solutions containing at least 0.1 percent formaldehyde. Check the standard for the particular operation; these examples are not an exhaustive list.

- BOTH WALL MOUNT&MOBILE AVAILABLE: This eyewash station has two empty eye wash bottles, you can hange it on the wall for emergency use, and all mounting hardware comes with the package. Or you can just carry bottles with you directly for any possible emergency involving the eyes without feeling bulky.
- PURSUIT OF QUALITY, PRACTICAL IN DESIGN: The eye flush kit is made of high-quality non-toxic polyethylene, which has excellent performance in chemical environments. There is a mirror on the kit, making it convenient to check eyes. Also, the bottle is soft, flexible and squeezable, and its drain pipe prevents waste water from flowing onto your body.
What does “within the work area for immediate emergency use” mean?
The regulation requires immediate access in the work area, but it does not name a maximum number of feet. An employer should assess the hazard and whether a worker can reach and use the facility promptly, without an obstruction or delay that would defeat emergency flushing.
In a 1996 interpretation, OSHA discussed 10 feet of unimpeded travel for highly corrosive chemical hazards in the circumstances presented, with an alternative based on advice from a physician or appropriate official. That letter is contextual guidance, not a universal 10-foot rule written into 1910.151(c). OSHA interpretation letters explain how the agency applied a requirement to described facts; they do not rewrite the regulation for every workplace.

Is ANSI Z358.1 an OSHA requirement?
ANSI Z358.1 is a detailed consensus standard addressing emergency eyewash and shower equipment, including location and flow. OSHA identifies it as a source of guidance, not an OSHA regulation. In its April 18, 2002 interpretation, OSHA stated: “ANSI standards become mandatory OSHA standards only when, and if, they are adopted by OSHA; ANSI Z358.1 was not adopted by OSHA.”
That distinction matters: 1910.151(c) is the binding general-industry baseline, while ANSI guidance can help employers evaluate what suitable equipment and installation may require. OSHA’s interpretation letters apply to the fact patterns they discuss, cannot create additional employer obligations, and may be affected by changes to the rules. The 2002 letter quotes the 1990 ANSI edition; it does not establish the full text of the current edition.

What distance, flow rate, and flushing duration should employers consider?
Do not mistake guidance figures for specifications printed in 1910.151(c). OSHA’s Infosheet 3818 summarizes ANSI guidance as specifying tepid flushing fluid at not less than 1.5 liters per minute (0.4 gallons per minute) for 15 minutes. The figure is attributed to ANSI guidance as summarized by OSHA; it is not stated in the regulation.
OSHA’s 2002 letter separately quotes a minimum of 20 gallons per minute (75.7 liters per minute) for an emergency shower under ANSI Z358.1-1990. This is a figure from the historical edition discussed in that letter, not verification of the complete current ANSI specification.

For distance, the regulation’s wording is “within the work area for immediate emergency use”; the 10-foot discussion belongs to the specific hazards and circumstances in OSHA’s 1996 letter. Apply the hazard and access facts to the actual work area rather than treating that number as a universal limit.

OSHA’s cited materials do not establish a universal weekly testing schedule under 1910.151(c). Do not attribute a particular interval to OSHA on the basis of that paragraph alone; consult applicable standards, equipment instructions, and qualified safety personnel for an appropriate maintenance program.
Which standards and jurisdiction should you check?
OSHA-approved state plans administer workplace safety and health programs in their jurisdictions. Employers should verify which jurisdiction applies and whether it has additional requirements. Also check standards specific to the operation, rather than relying only on the general-industry rule.
For a construction workplace, evaluate the actual chemical hazards and tasks, identify the standards that apply to that work, and confirm that selected emergency facilities are suitable and immediately accessible. A qualified safety professional can help assess the hazards, equipment, and applicable guidance.
