PROBLEM TO BE SOLVED: To provide fire fighting equipment which has a chemical tank with a simple structure to check the amount of a fire extinguishing agent contained in the chemical tank easily and supplies an aqueous solution of the fire extinguishing agent to a head to spray. SOLUTION: The fire fighting equipment feeds the aqueous solution of the fire extinguishing agent in which the fire extinguishing agent is mixed into water for fire fighting supplied by pressurizing by a fire fighting pump 10 during a fire to spray the aqueous solution of the fire extinguishing agent. The fire fighting equipment is equipped with the chemical agent tank 40 of an atmospheric open structure for collecting the fire extinguishing agent, a chemical agent pump 44 for supplying the fire extinguishing agent in the chemical agent tank 40 by pressurizing, a mixer 26 which mixes the fire extinguishing agent fed by the chemical agent pump 44 into the water for fire fighting supplied from the fire fighting pump 10 by pressurizing and makes the aqueous solution of the fire extinguishing agent flow out, a control valve 60 provided on a chemical agent feeding pipe to the mixer from the chemical agent pump 44 to control the amount of the fire extinguishing agent to be fed, and a chemical agent control panel 62 for controlling a degree to open the control valve in a manner to keep the aqueous solution of the fire extinguishing agent flowing out from the mixer at a prescribed concentration.
