The fluorescent solution includes a fluorescent dye and a stabilizing agent. The stabilizing agent may be a surfactant. A hydraulic fluid mixture is also disclosed which includes a fluorescent solution and a hydraulic fluid. ## Claims ### Claim 1 A method for detecting an accidental industrial fluid injection in a patient of an industrial fluid by machinery that operates under high pressure, the method comprising the steps of: providing the industrial fluid for use in the machinery, wherein the industrial fluid includes a fluorescent dye, providing a lamp emitting light of a wavelength between about 254 nm and about 500 nm, wherein the light causes the industrial fluid with the fluorescent dye to fluoresce, examining the patient with the light in a dark environment following a possible accidental fluid injection; and detecting a presence of fluorescence in the patient wherein the light causes the fluorescent dye to fluoresce, wherein the presence of the fluorescence in the patient indicates a possible accidental industrial fluid injection. ### Claim 2 (depends on 1) The method of claim 1, wherein the light of a wavelength between about 254 nm and 500 nm is a blue light, a violet light, or an ultraviolet light. ### Claim 3 (depends on 1) The method of claim 1, wherein the step of examining the patient with the light in the dark environment further comprises the step of washing a potentially fluid-injected affected area of the patient. ### Claim 4 (depends on 3) The method of claim 3, wherein the patient is examined with the light before washing, after washing, or both before and after washing. ### Claim 5 (depends on 1) The method of claim 1, wherein the step of examining the patient with the light in the dark environment further comprises identifying a point where the accidental industrial fluid injection occurred in the patient. ### Claim 6 (depends on 5) The method of claim 5, wherein the patient is washed at a point of possible accidental industrial fluid injection in the patient. ### Claim 7 (depends on 6) The method of claim 6, wherein the step of examining the patient with the light in the dark environment further comprises inspecting, with the light, an area of skin around a point of accidental industrial fluid injection in the patient before washing, after washing, or both before and after washing. ### Claim 8 (depends on 1) The method of claim 1, further comprising determining that the accidental industrial fluid injection has occurred in the patient by detecting fluorescence of the fluorescent dye of the industrial fluid under skin of the patient. ### Claim 9 (depends on 1) The method of claim 1, wherein the accidental industrial fluid injection occurred in the patient upon a pressurized release of the industrial fluid from the machinery. ### Claim 10 (depends on 1) The method of claim 1, wherein the industrial fluid for use in machinery is hydraulic fluid or fuel. ### Claim 11 (depends on 1) The method of claim 1, wherein the machinery is hydraulic machinery having a fluid storage tank, wherein the fluid storage tank is connected to, and in fluid communication with a hydraulic actuator, a hydraulic motor, or both, and wherein the fluid communication is through a hydraulic tube, a hydraulic pipe, or a hydraulic hose. ### Claim 12 (depends on 11) The method of claim 11, wherein the industrial fluid is hydraulic fluid, and wherein flow of hydraulic fluid drives the hydraulic actuator, the hydraulic motor, or both.
