Modern laboratories all have safety showers that are designed primarily to quickly rinse the whole body in the event of some chemical contamination from a spill or explosion. These safety showers are also an extremely effective and rapid way to extinguish burning clothing. If you do need to use one, be prepared for the shock from the cold water—these showers don t use warm water. The only disadvantage to safety showers is the distance that someone may need to mn to get to one. 

Even though personnel should always wear protective eyewear, splatter on the face may flow into eyes. Eyewash stations are designed to wash chemicals from the eyes in the event of an accident in the laboratory. Showers are designed to wash irritating chemicals from exposed body areas in the event of accident. Most are designed to deliver a specific amount of water in a specihc amount of time. Because skin and eye irritation are both associated with lab accidents, safety showers and eyewash stations are sometimes combined into a single unit. If they are purchased separately, both stations should be in close proximity to each other. 

Before designing a safety shower system, it is necessary to identify the most likely release points and to determine the likelihood of a person being present if a release does occur at that point. Release point identification can be carried out as part of a process hazards analysis. 

The eyewash and shower standard is developed by the Emergency Eyewash and Shower Group of the International Safety Equipment Association (ISEA) and approved as an American National Standard. The current edition was approved in September 2009, and designated ANSI/ISEA Z358.1-2009.
