Multiple robotic monitors are located in a hydrocarbon storage or transport facility. Each robotic monitor is communicably coupled to other robotic monitors and includes a heat sensor configured to detect heat emitted by a hydrocarbon tank of the hydrocarbon storage or transport facility. A controller is communicably coupled to the heat sensor and configured to generate a heat signature based on the heat detected by the heat sensor. A pump is communicably coupled to the controller and configured to exert pressure on a fire retardant, responsive to the generation of the heat signature by the controller. An outlet is mechanically coupled to the pump and configured to discharge the fire retardant at the hydrocarbon tank.

Short chainsaw bar assemblies, methods for using a chainsaw motor to operate an accessory, chainsaw drive chain cooling assemblies, methods for cooling a chainsaw drive, chainsaw motor drive adapter assemblies, methods for powering a belt drive from a chainsaw, and chainsaw and accessory assemblies are provided.

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 fire extinguisher monitoring system is described, said fire extinguisher monitoring system comprising a magnetic member for attachment to a fire extinguisher, a magnet, and a magnetic field sensor, wherein said magnetic field sensor is located proximal to said magnet to detect the presence of said magnetic member in said magnet's magnetic field. A method of monitoring the location of a fire extinguisher is also described.

There is provided a mobile firefighting unit comprising a container having a reservoir portion and a utility portion. The reservoir portion comprises a reservoir for storing a fluid. The utility portion comprises a main pumping station in fluid communication with the reservoir, and a mobile pumping station connectable to the main pumping station through a hose extending outside the container. The mobile pumping station is deployable for firefighting purposes. A heating system is also positioned within the container for heating the interior of the container. A lighting system provides lighting for the interior of the container. The mobile firefighting unit is readily and quickly available for rapid deployment in a fire scenario under various climate conditions.
