Confined or enclosed spaces are potentially dangerous places. They may be tanks, silos, pipes or anywhere you could be trapped .They are places where you could be affected by lack of breathable air, extremes of temperature, gas or dust, or loose powders, or liquids that might engulf you.
受限空间或者封闭空间，是潜在的危险场所。受限空间，可能是罐、竖井、管道或任何可能让你受困的地方。这些场所，可能会受到可呼吸空气的缺乏、极端温度、气体或者灰尘、松散的粉末，或者可能包围你的液体的影响。
Before entering, you should know what the hazards are, and how they will be controlled? You'll need a permit to work. How can you safely access an egress? Is there adequate ventilation for the work to do? Like welding, painting. If there are adequate lighting?
进入受限空间之前，你应该清楚危害是什么，以及如何进行控制？你需要工作许可证。如何安全地接近出口？工作是否有足够的通风设备？比如，焊接、喷涂。照明是否足够？
A safety plan should be in place to rescue an injured person.A safety attendant staying at the entry point, should monitor all activities near to and within the location, but should under no circumstances enter the confined space.
安全计划应该放在应放的位置上，以抢救受伤人员。留在入口处的安全员应该监控该位置附近及内部的所有的活动，不过，在任何情况下都不得进入受限空间。
Almost all workers who died in confined spaces are trying to rescue other workers who fainted due to lack of oxygen or exposure to toxic gases.
几乎所有在受限空间中死亡的工人，都曾试图去营救其他因缺氧或者接触有毒气体而晕倒的工人。
Don't just step in. Stop and think!
不要只是插手。要停下来想想！
A trained rescue team with breathing apparatus and other suitable PPE should be on standby. Throughout the job, there should be constant visual or voice communication between the safety attendant and the persons working inside the confined space.
训练有素的救援队伍应该随时待命，救援队伍成员必须配有呼吸器和其他合适的个人防护用品。在整个工作中，安全员和在受限空间内作业的人员之间应该保持持续的视觉或者语音方面的沟通。
Ensure there is adequate ventilation, and ensure you have a personal gas monitor. Be aware that disturbing sludge or water on the ground may release toxic gases. Oxygen levels should be constantly monitored, especially hot work is taking place. Barriers should be placed around all entry points to keep others away. And only authorized and trained persons may enter a confined space or act as a safety attendant.
请确保通风足够，并确保拥有个人的气体监测仪。一定要注意，地面上的污泥或者水会可能会释放出有毒的气体。我们应该不间段地监测氧含量，尤其，是正在进行的高温作业。另外，我们还应在所有的受限空间入口处周围设置障碍物，让其他人远离。只有得到授权和培训的人员，才能进入受限空间或者担任安全员。
Are you prepared?
