Gas Tester Refresher Training Module 气体检测仪进修培训课件 SECCO PRODUCTION TECHNICAL TRAINING TEAM SECCO 生产技术培训组 At the completion of the overall training effort you should be able to: 在完成所有的这些培训后，你应该能够： Demonstrate your ability to effectively setup the gas testers and check them against a facility check gas sample. 证明你能够高效率地安装气体检测仪，并能使用设施气体检测样品进行检测。 Demonstrate how to effectively use the Drager sample pump and sample tubes. 证明如何高效地使用Drager采样泵和采样管。 Explain how to effectively take a bag air sample for laboratory analysis. 解释如何高效地采取气袋样品，用于实验分析。 Demonstrate your ability to properly complete the appropriate permits associated with gas testing. 证明你能完全取得进行气体检测的相关许可证。 Explain some basic sampling techniques that need to be addressed. 说明一些需要解释的基本采样技术。 Explain PPE requirements for safely testing work site environments. 说明作业现场环境安全检测的PPE要求。 General Sampling Techniques 一般采样技术 Sample within close proximity to the area where work will be performed; this doesn’t mean at the manways of confined spaces. Use extensions to reach remote locations if appropriate. 在作业区附近采样，这并不表示在有限空间的作业通道里采样。在 必要的时候采取延伸措施以便到达比较远的地方。 Make sure you can safely access the areas to be sampled. 首先要确定你可以安全到达采样区。 Sample around vents, drains, sewer openings, flange joints, valve packing, pump seals and etc. 在排气管、排水管、下水道口、法兰接头、阀门衬垫、泵密封处等处采样。 Move slow during sampling efforts; as it takes a few seconds for substances to enter the instruments and for the instruments to respond to the samples. 在采样的时候慢慢移动，物质进入仪器要花几秒钟时间，仪器对样品的回应也要 花一些时间。 Always watch the displays on the MSA gas testers to verify that a sample reading doesn’t come in just below the alarm set point. Additional testing may be needed to detect potential problems. 不断观察MSA气体检测仪的显示屏，确定
