In the fumigation process F, the formalin is vaporized by supplying and heating the formalin in a state where the precision device is housed in the fumigation chamber 75 of the formalin fumigation device 74, and the biological agent is sterilized and decomposed by being left for a certain time. Is.

  In the cleaning process G, as shown in FIGS. 8 and 11, the operator puts the contaminated precision device into the cleaning chamber 61 from the inlet 64, and first, the precision device is a rough cleaning liquid in the cleaning tank 66, here. Then, it is immersed in alcohol for rough cleaning, and then the precision instrument is moved to the rinsing chamber 62, immersed in the alcohol in the rinsing tank 67, and finished and cleaned using a flowing high frequency ultrasonic cleaner 68. Subsequently, in the drying step H, the operator moves the precision device in the rinse chamber 62 to the drying chamber 63 through the jet towel 70, dries the precision device using the hot air dryer 69, and uses the UV lamp 71. Detoxify chemical and biological agents. At this time, the operator measures the radioactivity remaining in the precision instrument using the radiation measuring device 72 and visually confirms the analysis result of the chemical agent / biological agent analysis result display unit 73, thereby performing an appropriate cleaning operation. After confirming that it has been carried out, the precision instrument is removed from the outlet 65.

  In the reuse process I, as shown in FIGS. 7 and 12, the alcohol used in the cleaning process G is circulated and used in the cleaning chamber 61 and the rinse chamber 62, respectively. That is, by driving the rough cleaning liquid circulation pump 55a, the used alcohol stored in the cleaning tank 66 of the cleaning chamber 61 is discharged to the prefilter 79 and the activated carbon adsorption filter 80 through the rough cleaning liquid recovery hose 57, The prefilter 79 removes contaminating fine particles of the radioactive substance, the chemical agent, and the biological agent from the used alcohol, and the activated carbon adsorption filter 80 removes the contamination residue of the chemical agent and the biological agent.
