Abstract
Apparatus and methods for integrated emergency wash systems. Various embodiments pertain to integrated shower and eyewash emergency wash systems, including those that are particularly space efficient. Other embodiments pertain to emergency shower nozzles that provide sprayed water in sheets, especially a cylindrical sheet that generally describes the perimeter of the shower spray area, providing the user a significantly quicker removal of contaminant material during a shower. Still further embodiments pertain to improved flushing systems, especially flushing systems adapted for the space efficient, low flow integrated systems described herein.
Claims18
A system for emergency washing, comprising:
- an overhead shower having an inlet and adapted and configured to provide a downward spray pattern of tempered water;
- a thermostatically controlled mixing valve having a body with an inlet for cold water, an inlet for hot water, and at least one outlet, and an internal mixing assembly adapted and configured for combining the water from the cold inlet with water from the hot inlet and providing tempered water to the at least one outlet;
- a first shutoff valve having an inlet receiving tempered water, an outlet providing tempered water to the inlet of said shower, and means for actuating between flowing and non-flowing configurations;
- a pivoting shutoff valve having opened and closed positions, an inlet receiving tempered water from said mixing valve, first and second members that pivot relative to one another, and an outlet, wherein in the opened position said first and second members provide fluid communication from the pivoting shutoff valve inlet to the pivoting shutoff valve outlet, and in the closed position prevent the pivoting shutoff valve outlet from receiving water from the pivoting shutoff valve inlet;
- and
- a pivoting eyewash assembly having an inlet receiving water from the pivoting shutoff valve outlet in the opened position and including a plurality of spray orifices adapted and configured for the upward spray of water into the face of a user, said eyewash assembly being pivotal with one of said first or second members from the closed position to a location within the downward spray pattern in the opened position.
