SELF-CONTAINED BREATHING APPARATUS (SCBA) WITH SAFETY QUICK DISCONNECT FOR PERMITTING SAFE AND READY ACCESS TO A REPLACEMENT BREATHING COMPONENT

摘要

A self-contained breathing apparatus (SCBA) is disclosed which Is able to safely and quickly connect to a replacement breathing component without breaking the seal so that the replacement breathing component can supply additional breathing capacity to the user This is accomplished through a novel multi-port safety quick disconnect that will not allow a user to disconnect from a current breathing component unless a replacement breathing component has been properly connected to multi-port quick disconnect The quick disconnect prohibits a user from (i) accidentally disengaging a current breathing component until a replacement breathing component has been connected, and (n) inadvertently connecting the mouthpiece to ambient air.
