In order to reduce the potential risk caused by the toxic substance (carbon tetrachloride...etc) operation in college laboratory, pre-investigation by questionnaire, policy promotion meeting and providing recommendation through on-site expert inspection had been done to remind all college the importance of toxic substance management and to provide necessary correction advices. 204 representatives from 57 academies joined the policy promotion meeting and 42 college-scale questionnaires were replied that illustrated the operational background information, like toxic substance management, the operation quality and quantity of toxic substance…etc. Furthermore, 81 laboratories among 40 departments of 20 colleges were inspected with experts on-site. The investigation demonstrated that there are 97.6% colleges have environment and safety relative framework; 83.0% has toxic substance management regulation, however, there are still 5 toxic substance operation colleges have no toxic substance management regulations. All on-site inspected laboratories have hood to collect the fume during operation and 49.3% has installed activated carbon adsorption equipment with uncertain cartridge replacement cycle.
Totally 1462.6 kg carbon tetrachloride, chloroform, trichloroethylene and tetrachloroethylene is consumed a year and 508.25 kg/yr is released annually before correction recommendations are taken. However, only 61.56 kg/yr, equal to 57.9% reduction rate, will be released if correction recommendations are taken.
Conclusively, the application of carbon tetrachloride, chloroform, trichloroethylene and tetrachloroethylene in surface cleaning process could be controlled by limited restriction. To improve the toxic substance management in college, providing a common-adaptable management plate with integrative functions are recommended. Moreover, evaluation the toxic substance releasing parameter by standard laboratory model (like chemical, medical department…etc) will provide import basis for further precise correction recommendations.
