Risk-reducing in chemical experiments in universities is an urgent task. Although environmental arrangement of chemical laboratory for undergraduate students at the moment does not look enough, it is difficult to obtain a sufficient cost to improve in many of recent universities.
Therefore, we tried to set up local exhaust ventilation at low cost by using already existing facilities to improve environments of chemical laboratory. In the present report, we introduce cost-effectiveness for setting up local exhaust ventilation and educational effects for undergraduate students who used the local exhaust ventilation.
