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.
Emergency Shower Requirements
Plumbed Shower: An emergency shower permanently connected to a source of potable water

Eye/Face Wash Station Requirements
An Eye/Face Wash Station is a device used to irrigate and flush both the face and the eyes.
- Heads
- Positioned 33″—45″ from floor

- *Consult a medical professional to determine the appropriate distance for harsh acids and caustics (high hazard=closer distance)
- The location of the eye/face wash station shall be in a well-lit area and identified with a sign
- Eye/face wash stations shall be on the same level as the hazard
- Eye/face wash shall be located in an area that requires no more than 10 seconds to reach.
- Maintenance and Training
- A plumbed eye/face wash station shall be activated weekly to verify proper operation
- Gravity-feed units shall be maintained according to the manufacturer’s instructions
- All employees who might be exposed to a chemical splash shall be trained in the use of the equipment
- All eye/face wash stations shall be inspected annually to make sure they meet ANSI Z358.1 requirements
Personal Eye Wash and Eyesaline Requirements
A Personal Eye Wash is a supplementary eye wash that supports plumbed units, gravity-feed units, or both by delivering immediate flushing fluid. Personal eye wash units can provide immediate flushing when they are located near the workstations. Personal eye wash equipment does not meet the requirements of plumbed or gravity-feed eye wash equipment. Personal eye wash units can support plumbed or gravity-feed eye wash units, but cannot be a substitute. Personal eye wash can be delivered through bottles of saline solution designed to simulate human tears. Individual bottles can be carried by workers and provide relief in the crucial seconds until an approved eye wash station installation can be reached.
