Terry, You are so right! When I list potential corrective actions, I list even the ones that are unacceptable. The reason I do this is that sometimes people...
Bill, The significance of the consequences (i.e., a dead battery) depend on the conditions. For example, if a dead battery occurs at home it might only be an...
Tim, It's good to hear from you and to know that you're still providing good insight. A dead battery is certainly a consequence. But it is also a cause of...
John, Thanks ever so much. You are on solid ground. I hope you have been reading the thread on my neighbor's dead battery. In your example, I take it that the...

Bob, I started a table at http://groups.yahoo.com/group/Root_Cause_State_of_the_Practice_II/database?method=reportRows&tbl=9 where people can add their classic...
Bill, I think of significance in terms of risk significance. Consequences are causes of, or precursors to, other consequences. In other words, part of the...
Ted and Bob, I added Bhopal as well as Donora, PA. If you scroll to the bottom you'll see all the data to now. I will send you an update whenever you like and...
Tim, Thanks ever so much. When quantitative risk analysis is available it is one very important aspect of significance. Take care, Bill Corcoran W. R....
How do I know which hazards to protect against? This is a question that I get over and over again. Usually someone asks me that question in a situation in...
Bill, Protect against hazards commensurate to their risk significance. Lower the hazard's risk significance by reducing: 1) The likelihood of the hazard's...

Kent, For starters, I'd look at the process used to provide the training and compare it to the INPO and NRC guidelines for licensed operator training with a...
