A firefighting utility tool including a handle member and a tool head. The handle member has one of a variety of tool heads attached to a bottom side thereof. The handle is a solid tubular member with a hollow interior that allows water to pass therethrough. The top end of the handle member has a hose coupling located thereon such that a hose can be connected and water can flow into the hollow interior of the handle member. There are a plurality of holes located in the handle member toward the bottom end of the handle member. The holes allow water to exit the handle. The tool allows water to pass through the handle and out of the plurality of holes such that the water can be directed toward a fire without interfering with normal operation of the tool.

Aspects of the disclosure include providing additional sources of water, and additional means for delivering the additional water, as needed in a fire emergency. A system in accordance with an aspect of the present disclosure provides pumping means, conduit for delivering water from a local source to the pump, and conduit for delivering the water as needed to fight a fire.

A sprinkler support frame coupling device that is capable of allowing a horizontal bar having a square section so as to install a sprinkler thereon to be simply and firmly fitted to a support frame mounted on a ceiling. The sprinkler support frame coupling device is configured to allow a lever of a bracket to be pushed by a user's hand so that the bracket is firmly coupled to a support frame.

An extinguishing lance for electrical devices that are burning, has a holding portion having a handle part for operation, an extinguishing-agent feed having a coupling device for connecting a pressure hose for extinguishing agent, and a tubular extinguishing portion, from the free end of which extinguishing agent is introduced, under pressure, into the object that is burning. The extinguishing portion tapers to a point at the free end and has a constricted, hollow flow cross-section for extinguishing agent conducted under pressure. The extinguishing portion and its tapered, additionally hardened end are produced from stainless steel. The extinguishing portion has, at least in the region of the holding portion, a voltage-insulating coating, which is electrically insulating for electric voltages U ≥ 500 V. Thus, the minimum legal requirements for protection against thermal hazards, against mechanical overloads, and against electrical hazards are reliably met.

A nozzle plug for a deluge fire protection system having nozzles connected with a pipe network, the nozzles having a pipe connection with a nozzle chamber and a nozzle orifice allowing for the flow of water toward a deflector for dispersal, includes a plug body configured to fit within the nozzle chamber and/or nozzle orifice and form a seal of the nozzle orifice; a deformable component connected with the plug body configured to retain the seal of the nozzle orifice up to a predetermined pressure level above atmospheric pressure within the pipe network and to deform when a current pressure with the pipe network exceeds the predetermined pressure level and release the seal of the nozzle orifice to allow for the flow of water through the nozzle orifice; and wherein the deformable component is configurable to calibrate a deformation point corresponding to the predetermined pressure level.
