台阶梯

Employees should avoid using stepladders, which will elevate the worker to a height of 2 M or over. 雇员要到超过2米以上高度的场所进行作业时应避免使用四脚梯。

Today stepladders carry labers several inches long that warn,among other things,that you might-surprise!-fall off. 能给我解释一下其中的语法结构吗?我看得不是很懂?请众位高手帮忙解释解释,多谢阿!

Today, stepladders carry labels several inches long that warn , among other things, that you might-surprise!--fall off. 现在，梯子上警告标签有几英寸长，除了警告你其他可能发生的意外情况外，还警告你可能会摔下来，简直是莫名其妙！
