Safety Logos

My dads company is having a safety slogan/logo contest and he is needing some ideas. The first place i thought of was Yahoo answers to get good ideas so here i am. The instructions say
“The slogan/logo should reflect the goals for 2008, ie. some of the goal sthat will be reflected in the 2008 safety program are:

Voluntary Protection program
Hand safety
First aid cases
Zero Recordable
Life critical procedures (i.e. confined space, energy control, safe work permit employee responsibility and accountability)
——————
No entry will be accepted that is offensive derogatory or has messages that are clearly unacceptable.

slogan/logo will be accepted with or without graphics.

Thank you all in advance! He has to turn in the slogan/logo before 11/14/2007 12:noon. so that gives him tonight and 2morrow to work on it. Thank you all once again!

sorry if i misplaced in category!
