很多人觉得，设备使用了安全光栅，就绝对的有安全保障了。
Many people think that if the equipment uses a safety grating, it is absolutely safe.
甚至都不注意对上岗员工的安全宣导了。
They didn’t even pay attention to the safety propaganda for the employees on duty.
其实，这样的认为是错误的。
In fact, this view is wrong.
为什么呢？
Why?
因为无论多好的安全防护，都不能保障百分百安全。
Because no matter how good the safety protection is, it cannot guarantee 100% safety.
比如当安全光栅出现故障时，就不能正常发挥作用，如果我们不经常检查，很可能就没有发现安全光栅已经失去保护作用了。
For example, when the safety grating fails, it can’t work normally. If we don’t check it often, we probably won’t find that the safety grating has lost its protection function.
比如安全光栅本身存在的盲区。
For example, there is a blind area in the safety grating itself.
如果我们没有及时的意识到这个问题，在盲区违规操作，一样会给我们的安全带来隐患。
If we do not realize this problem in time, illegal operation in the blind area will also bring hidden dangers to our safety.
所以，在使用安全光栅的时候，也要定期检查，同时也要做好安全的宣导工作，保证每一个上岗员工严格按照操作流程操作，不能违规操作。
Therefore, when using the safety grating, it is also necessary to check it regularly, and at the same time, it is also necessary to do a good job of safety propaganda, so as to ensure that every employee on duty operates in strict accordance with the operation process and can not operate in violation of regulations.
