Suggested guidelines for leaving the laboratory

A lot has been written on safety guidelines for working in laboratories. However, an important aspect which is often overlooked is what needs to be done if you happen to leave your laboratory last.

在留下您的家之前，不言而喻，您会确保在留下以下内容：

Almirah with cash and valuables is properly locked
窗户是正确的螺栓固定和烤架锁定
所有电气和电子产品都换了off and unplugged
Taps are properly closed
燃气燃烧器和烹饪燃气管线阀门关闭
Finally the house is properly locked

As far as your home is concerned your main concern is to secure it from thefts, fires and minor electrical hazards. Now imagine the hazard potential posed by a laboratory which houses dangerous chemicals and toxic products in addition to compressed gases and other utilities. The danger is further compounded by the fact that in case of any mishap there would be no one around to know what is happening inside a closed laboratory and little can be done to control such situations.

As a responsible laboratory worker you have to ensure that no untoward happening takes place when no one is around so before leaving your laboratory you should take a quick round to ensure the following:

All gas lines are turned off
水点关闭，没有溢出的容器
Vacuum and compressed air lines are switched off
No hot plate or rotary evaporator or any other heating device is left on
None of the instruments is left on except for chromatographs or other equipments with programmable auto sampler sample introduction systems
试剂瓶返回各自的架子，工作台没有杂乱
Weighing balance bench and chamber are clean and chamber protection shields are closed
No bottle is left uncapped and in particular those containing acids or other corrosive materials
Isle and passages are free of any obstructions
There are no spillages on work benches or lab floor
在离开之前，请卸下所有实验室防护服和安全齿轮，如实验室内的实验室，手套，安全护目镜等
在离开实验室之前关闭灯，空调和其他电气设施
Remember to sign the laboratory register and enter the time you leave the laboratory. This is important as it it can be helpful in investigations in case of any subsequent mishappenings. In case there is provision for electronic entry and exit remember to swipe the card before leaving
