| Summary: | 碩士 === 長榮大學 === 職業安全與衛生學系碩士班 === 98 === The waste liquid was variety in the school laboratory. It could cause chemical accident if the control of storage management wasn’t been executed properly. Therefore, the waste liquid had been moved to Waste Water Treatment (WWT) for disposing. The composition of waste liquid was complex and the identification of waste liquid was not clear, so there would be potential damage for the recycling with unknown qualities. The purpose of this study focused on analyzing and discussing the compound of waste liquid with Nuclear Magnetic Resonance (NMR), Gas Chromatograph Flame Ionization Detector (GC-FID) and Gas Chromatography Mass Spectrometry (GC-MS). The study tested the flash point with magnetic stirrers and open cup flash point in the school lab. According to the data and information from laboratory test, using the foam fire-extinguishing equipment. It could provide improvement that prevents fire accidents and makes the conference of emergency plan.
The compound of waste liquid from school laboratory was multiple flammable liquid through the analysis of the study. It would be categorized in the 13th of “Labor Safety and Healthy Facilities Rules” and be listed in National Fire Protection Association (NFPA). The foam fire-extinguishing equipment could be effective for the waste liquid fire that had been known from the fire test. There was aware that when the extinguisher used the foam fire-extinguishing equipment, the vision of extinguisher might be blocked. Therefore, there should be an extinguishing commander to point the way and adjust the ankle that would be efficient and quick to extinguish the fire.
