4 laboratory safety regulations

In order to do a good job of experiments, to ensure the success of experiments, to protect the experimental instruments and equipment, to maintain the safety of the experimenter, to prevent all experimental accidents, the formulation of this laboratory safety regulations

First, not to carry out experiments, you should master the process of operation and the principle of clarification so that the nature of equipment and experimental reagents. The nature of the equipment and experimental reagents. Estimates of the possible dangers of the experiment, in the operation of the precautionary.

Second, before the start of the experiment, check whether the instrument is intact, the device is correct and stable. When the experiment is in progress, you should always pay attention to whether the instrument is leaking, leaking, broken, and whether the reaction is normal, etc.

iii.

Third, it is strictly prohibited to smoke or eat in the laboratory. The experiment is completed to carefully wash their hands. Water, electricity, lights and instruments and equipment used, it should be turned off immediately.

Fourth, absolutely do not allow arbitrary mixing of various reagents to avoid accidents. Can not touch the drugs with their hands, do not put the nostrils to the mouth of the container to smell the reagents, not to taste the flavor of any reagent.
