A Notice at Library

Had a lovely day with a friend of mine, going to see cherry blossoms, visiting a library and a bookshop, and having coffee. I captured this notice at the library. It seemed to be aimed at children because of the illustrations and the simplest forms of Japanese language used. 

I've clarified one by one as follows. Or please take a guess and check with the following answers. In anyway I hope they make sense to you.

(The upper row from the left)
- Be quiet.
- Are your hands clean? 
- Ask any question to staff.
- Re-shelve your book.
- Treat books with respect.

(The lower row from the left)
- Be careful (not to damage books?)
- Keep the due date.
- Don't push a book into the shelf. 
- Don't bring food or drink.
- Have a good posture when reading.
