Warning signs
警告标志
This is the machine hall. Do you notice that sign over there - the red circle with a diagonal line through it? It means you mustn’t smoke here. A blue circle shows something is compulsory - so that sign over there means you must wear goggles in that area lo protect your eyes. The yellow triangle with a black border over there is a warning sign. It means the floor might be wet.
“这是机房。大家注意那边有个红色圆圈标志当中有个斜线吗？意思是这里禁止吸烟。蓝色圆圈标志表示必须要做的，那面那个标志就是在那个区域为了保护眼睛大家必须戴上防护镜。那边那个带黑边的黄色三角形是警告标志。意思是地板可能湿。”
