FAQ Where must eyewash stations or showers be placed in a facility? While there are several requirements throughout the 1910 standards providing that eyewashes, showers, or drenching facilities be available under certain circumstances, there are no specific requirements for locating or mounting the equipment. In a letter of interpretation from 04/18/2002, OSHA states that “it is the employer’s responsibility to assess the particular conditions related to the eyewash/shower unit, such as water temperature, to ensure that the eyewash/shower unit provides suitable protection against caustic chemicals/materials to which employees may be exposed.” Also, in a letter of interpretation dated 11/01/2002, OSHA states that “When determining whether the eyewash or shower facilities are suitable given the circumstances of a particular worksite, OSHA may refer to the most recent consensus standard regarding eyewash or shower equipment … ANSI Z358.1, as well as other recognized medical, technical, and industrial hygiene sources.” So even though it has not been adopted by reference, you may wish to consult the ANSI Standard for Emergency Eyewash and Shower Equipment, Z358.1, for guidance in this area.
