A fire hose coupling comprises a body having a first end connected to a fire hose and a second end having either male or female threads or, alternatively, a quarter-turn sexless coupler. The fire hose coupling comprises a recessed portion formed in an outer surface of the body. The recessed portion is shaped to define a visuotactile directional indicator such as an arrow. The recessed portion may include a light-reflecting surface to enhance visibility such as a super reflective metal film, a photo luminescent coating, or a phosfluorescent coating. The recessed directional indicator may be formed in female, male or sexless (Storz) couplings.

A system and method for providing a fire department connection (FDC) to a building fire sprinkler and/or standpipe system comprising carrying and transporting the FDC on a pumper truck with the fire department. The FDC is removed from the pumper truck and coupled to the inlet of the building with a quick-connect. The quick connect is capable of releasably coupling the FDC to the building inlet of a building fire sprinkler and/or standpipe system. When finished, the FDC is removed from the inlet of the building and replaced on the pumper truck. Thus, the FDC remains in the custody of the fire department

Fire hose couplings and adapters are configured to receive, by any of various types of interconnections, a wide range of attachments enhancing the utility of the associated fire hose. The attachments are secured to the coupler or adapter by means of an appropriate locking engagement, such as by a dovetail connector, setscrews, chemical attachment, adhesives and the like. The attachments cover a broad range of handles, reflective and directional devices, analog and digital sensors/monitors/indicators, and carabiners, and both threaded and unthreaded studs adapted for appropriate receipt of any of a broad range of attachments or uses.

An emergency air breathing system according to various aspects of the present technology is configured to utilize a standard operational firehose to refill an air tank carried by a firefighter or otherwise provide breathable air to the firefighter through their SCBA while fighting a fire. Various embodiments of the emergency air breathing system comprise a coupling device that can be selectively connected on a first end to a fire hose nozzle and a fire hose at a second end. A conduit section extends between the first and second ends and is configured to redirect a supply of breathable air out from a port in the conduit section and through a valve housing that can be selectively connected to the firefighter's air tank or a transfill hose of the SCBA.

Disclosed is a connecting device. The disclosed connecting device includes a connecting unit whose inside is penetrated and opened and closed according to rotation of a rotor provided therein, and an opening/closing unit that is rotatably coupled to the connecting unit and opens and closes the inside of the connecting unit by rotating the rotor, when being rotated with respect to the connecting unit.

Methods for drafting or transferring water from a water supply to a fire pump in fire service include a strainer, the strainer having a hood member with an open bottom inlet having an inlet aperture, an outlet having an outlet aperture, a suctioning structure extending away from the open bottom inlet of the hood member, and the suctioning structure having a base offset from the open bottom inlet. Method of using the strainer including immersing a strainer in a water supply, fluidly connecting the outlet to a suction side of a pumping apparatus, activating the pumping apparatus, transferring water through the hood member, directing the strainer toward the bottom of the water supply and maintaining the strainer at the bottom of the water supply.
