Good morning Dan,
I do agree that there should be more facility inspections to check for proper training, but usually the only time we see these inspectors are when there is an accident of this type or if a disgruntled employee files a complaint (safety) to OSHA.
When I was in the military we knew we had inspections from higher headquarters very 12 - 18 months and it was not good for any one to fail these and they looked for everything from basic training techniques to whether an individual and unit actually knew what they were doing.
We are very fortunate that we have a CEO that is very safety conscious and we have programs in place that sends out reports once a month that shows what employee training that has been conducted and what employee training re-evaluations are due with in the next six months.
As a trainer I would love to see a 0 accident/incident rate, but as with children, you can raise them the best you can, give them the right direction, but ultimately it is in their hands to take that life time of learning and properly use it. As the old adage is. "You can lead a horse to water, but you can not make them drink".
Again it is a sad day when a death occurs within our environment, or anywhere, especially one that could have been prevented.
