Creating a confined space presents the potential for unsafe atmospheres. If dangerous levels of a gas are detected, evacuate the effected area immediately. Do not re-enter the area until safe conditions are restored. 防止不安全环境的形成确保合适的场地通风以及大气监测系统的安 装与使用。把有可能发生的不安全环境控制在最小范围内。一旦检测出 危险气体，请立即撤离现场。直至恢复安全，才能返回该区域。 Ventilate working areasPrevent any leaking gases from accumulating. Vent all gases to the outside to an area that is safely away from people and away from any possible ignition source. Before restarting the equipment, ensure that all parts affected by repairs have been restored to their proper operating condition and that the lines have no leaks. 通风的工作环境防止泄漏气体的浓度升高。把所有气体排放至安全 区域，远离人群和火源。在重启设备之前，确保所有部件恢复其良好的 性能，所有的管路没有泄漏。 Prevent injuryWear safety glasses and other appropriate PPE when the MSDS, task, or code dictates. Ensure that all tools and instruments used are in good conditi
