Emergency Shower & Eyewash Station Requirements Per ANSI/ISEA Z358.1-2009 Standard Eddie Burlem, June 9, 2016February 16, 2024 In our last blog post we talked about Occupational Safety and Health Administration’s (OSHA) regulations in regards to Emergency Showers & Eye Wash Stations. We also introduced American National Standards Institute’s (ANSI) standards that cover all situations where employees are exposed to hazardous materials. These regulations help employers select and install the correct emergency equipment that meets OSHA requirements. In this blog post we will expand upon and list out specific Emergency Shower and Eyewash Station requirements listed in the ANSI/ISEA Z358.1-2009 standard.

Personal eye wash units can support plumbed or gravity-feed eye wash units, but cannot be a substitute.

Individual bottles can be carried by workers and provide relief in the crucial seconds until an approved eye wash station installation can be reached.
