Abstract
Eyewash stations can go through extended periods of disuse, allowing for the growth of bacteria and other substances in the stagnant water in the supply passages. Water dispensed from such the eyewash station can come into contact with or be consumed by a user. Embodiments of the invention provide a system that can automatically flush stagnant water from eyewash stations on a timed basis to minimize the possibility that contaminated water is delivered to a user. In addition, the automatic stagnant water flushing system according to embodiments of the invention can provide temperature-based flushing systems to avoid the dangers or discomfort associated with the delivery of excessively hot or cold water to a user.
