The information presented here

   
 

... is in general presented because

the law requires that it be presented,

not because we think you've never heard it.

Some of it is rather intuitive, some is "common sense," some is not very obvious at all.  You may know a lot of it.  Study it all anyway, for review and updates.

If anyone ever tells you that working safely is a matter of "just using your common sense," please tell them that this is generally a very bad idea.  Sometimes even the most "common sense" safety principles escape the focus of people, especially highly motivated and intelligent people working on interesting projects and under a deadline.

Your comments on ways in which the program might be improved are welcome; send them to swihart@purdue.edu.
