Abstract
Methods and apparatus for washing systems, both industrial and residential. Some embodiments pertain to face washing systems that provide a gentle upward flow of water for washing a person's face, but which can be easily reconfigured to provide a downward flow of aerated water for washing of the user's hands. Other embodiments pertain to visual indicators to help a user in a dark environment in the use of an emergency eyewash system. Yet other embodiments pertain to eyewashing systems incorporating filters that are automatically flushed of debris. Still further embodiments pertain to emergency eyewashing systems in which a mixing chamber is located downstream of a thermostatically controlled valve to reduce the possibility of a hot temperature spike being provided to the eyewashing outlet apertures, which could be harmful to users.
