阅读下列短文,根据短文中的信息完成文后表格。在答题卡标有题号的横线上,写出空缺处所填单词的正确形式。(每空一词)
Every place offers the possible dangers for getting hurt, even staying at work. We may face dangers like walking into desks or chairs, receiving unexpected cuts from a paper knife and so on. Industrial jobs have similar and more dangers like getting body parts hurt by machines or falling from a height.
No one wants to get hurt. Some accidents are avoidable(可避免的). Most accidents  happen because of common things seen every day—an open desk drawer, a chair pulled out too far, water on the floor and so on. We slowly get used to these things we see every day and never think about what they could possibly become in the future.
Think about the following to prevent dangers to yourself and others:
1. If there is something you see and know may become a danger for yourself or others, do something about it. Close a desk drawer, clean up or put a sign over the water, turn off the power before leaving, and so on.
2. Get extra persons’ help and support on a task that is too hard for a single person.
3. Study the situation and think what could possibly happen and change if necessary. Do it before something happens and you won’t have to say some day, “ I should have… How sorry I feel…”
To use an old phrase “ Safety is everyone’s duty.” Looking down on it could lead to being hurt. Keep the rule in mind every day “ Everyone wants to go home in the same condition they came to work in –or better.”
