Abstract: A conventional, full-scale emergency shower and eyewash unit uniquely retrofitted for use in work areas where water is not easily provided. An emergency shower and eyewash unit can be retrofitted at piping located near its top to be in fluid communication with a large capacity container suitable for containing liquid and located above the top of the shower/eyewash unit so that fluid (i.e., water) contained therein can flow into the shower/eyewash unit using the benefit of gravity. Additionally, a liquid release valve can be located near the base/bottom of the shower/eyewash unit so that liquid contained in the container can periodically be released during routine maintenance and cleaning. Conditioning means are also described ensures that fluid/water contained in the container is not allowed to become harmful through bacterial or microorganism growth, which is common in stagnant liquids such as water, and to maintain liquid temperature.
