Appendix H. Limited Water Sprinkler Design

This design is one method that may be used to provide limited water supply automatic sprinkler protection

for gloveboxes. As an assembly, the design is not "listed" or "approved," but the individual components

are all listed for fire protection application. Use of this system should be approved by the DOE AHJ.

The system consists of pressurized-water portable fire extinguishers (with the number varying depending

on criticality requirements) piped to a common manifold and then to the discharge point. A low pressure

switch activates a fire alarm when the system discharges. Restricted orifice sprinkler heads are used and

a fill port is provided for charging the system.
