The Importance of

                                     Asking “Why?”

                                                    by Katie Mackey
                               A cornerstone of any safety program
                             should ask “Why?” when issues occur.

                 e do not live in a perfect world.
                 You can plan, educate and
         Wprepare for the worst and just
         hope for the best. In fact many would
         probably say, those companies who
         work on continuous improvements are
         not only better equipped to deal with
         circumstances when they arise but they
         have fewer accidents, incidents and
         near misses than companies who do not.
           Regardless of where  your  organiza-
         tion falls in the safety spectrum of “to-
         tally unprepared” to “we’re  ready for
         anything”, there is one very important
         lesson that you can always remember
         when  something  goes  wrong  or  some-
         one notices a potential issue. That key
         point is to ask “Why?”
           It is a three-letter word that many
         times gets overlooked,  in  the  rush  to
         clean  up  or  get back  to  work.  But  it
         can reveal areas that may only require
         a  simple  fix  to  keep  something  from
         happening again. The following three   According to the image in the service manual (inset) there should be no rope guard above
