  • 如何安全使用和维护实验室
    来源:最新澳门网址大全 浏览: 发布日期:2017-08-04
      随着现代实验室的日益增多。实验室人员如何正确安全的使用通风柜?如何正确的维护通风柜?通风柜是实验室设备中的重要组成部分,在科学的实验室环境中,良好的通风效果对于创造安全洁净的实验室环境、保证实验条件的科学性、可靠性以及实验过程中的安全性非常重要。在我们使用通风柜时,要注意以下几点:
    With the increasing number of modern laboratories. How do laboratory personnel use the fume hood properly? How to maintain the fume hood properly? Fume hood is an important part of laboratory equipment, in the scientific laboratory environment, good ventilation effect to creating safe clean laboratory environment, guarantee the scientific nature of the experimental conditions, the reliability and the security is very important in the process of experiment. When we use the fume hood, pay attention to the following points:

      1、室内空气温度在-5℃至+40℃之间,24小时平均值不超过+25℃。
    1, the indoor air temperature between 5 ℃ and + 40 ℃, the average no more than 24 hours + 25 ℃.
      2、实验室内在不使用通风柜时也要时常通风,这样对试验人员的身体健康有益。
    2. The laboratory should always be ventilated when it is not used in the ventilation cabinet, which will be beneficial to the health of the test personnel.
      3、当2个以上的通风柜共同使用1个风机时,为避免操作失误或不当,风机的 “开”“关”只能由1个操作人员来控制;如另外一个通风柜暂时不使用或要停止使用,可使用风量调节阀来封闭通风口;避免相互重复“开”“关”风机,这样不但对风机的寿命产生损害,对实验也不精确。
    3. When two or more fume hoods use one fan, the "open" of the fan can only be controlled by one operator to avoid errors or improper operation. If another fume hood is temporarily not used or should be stopped, use the air volume control valve to close the vent; Avoid the "open" and "turn off" fan, which can not only damage the fan's life, but also the experiment.
      4、通风柜在使用时,避免人员走动带来的逆流风向对通风柜的干扰。
    4. When using the fume hood, avoid the interference of the countercurrent wind caused by the movement of personnel to the fume hood.
      5、通风柜在使用时,每2小时进行10分钟的补风;使用时间超过5小时的,要敞开窗户,避免室内出现负压。
    5. When the fume hood is in use, every 2 hours shall be filled with 10 minutes. Use more than 5 hours to open Windows and avoid negative pressure inside.
