各学院、中心（平台）、实验室：

与危化品安全、生物安全、用电用气安全相比，实验室用水安全容易被忽略，但作为实验室人员，我们绝不能掉以轻心，实验室水龙头总阀未关，或只关闭分支管路，使水压导致分支管路破裂，水流外溢到实验室地面等事件也时有发生。在此，提醒各实验室人员要做到：

1.了解实验室自来水各级阀门的位置、出水情况，节约用水，杜绝出现水龙头打开而无人监管的现象。

2.输水管应使用橡胶管，水管与水龙头以及设备仪器的连接处应使用管箍夹紧。定期检查输水装置连接胶管接口和老化情况，使用频繁的胶管，建议一到两个月更换一次。

3.每天最后离开实验室的人员要检查实验室的水、电、气关闭情况，并在值日记录本上做好记录。

4.实验室发生漏水和浸水时，第一时间关闭水阀，上报维修;水管爆裂时，应切断室内电源，转移仪器设备，组织人员清除积水。

5.建议实验室在建设时安装地漏。如果没有条件安装地漏，建议安装漏水报警器。

Dear all:

Compared to hazardous chemicals, biological, electricity and gas usage, the safe use of water in laboratory is often overlooked. As laboratory personnel, we should pay attention to risks such as leaving the main water valve open or only closing the branch pipeline which may resulting in the branch pipeline to burst and water spilling in laboratory.

Here are some water safe use tips:

1.Understand the locations of various water valves in laboratory and avoid the situation of leaving taps running.

2.Rubber pipes should be used for water transportation, and the connections between water pipes, faucets, and equipment should be clamped tightly with pipe clamps. Regularly inspect the connections and aging of the rubber hoses in the water transportation system. Suggest to replace the rubber hoses one to two months that are frequently used.

3.The person who leaves the laboratory last every day should check that the water, electricity, and gas in the laboratory are turned off and make a record in the duty record book.

4.When there is a water leakage in the laboratory, close the water valve immediately. In case of the water pipe burst, the power supply should be cut off, equipment and instruments should be transferred.

5.Recommand laboratory to install a floor drain or water leakage alarm during construction.
