In my personal life I went one year after the earthquake and spoke to the hospital personnel who were affected by the quake.
Potted plants in ceramic pots are like hand grenades and threw shrapnel of the pots. (Not a good idea in earthquake zone.)
One year after the earthquake, the nurses put up guards on the medications to prevent them from falling out in the next one. The clinical lab secured the blood bank refrigerator so it would not fall over (great idea) with webbing material like automobile seat belts.
Unbelievably, the engineering department and the time administration of the hospital did nothing, as one of the representative in the interview said 'doing something might give us a false since of security'.
So they did nothing.
As indicated in the article, this story was also swept under the carpet.
I truly believe that the time out jumper is safer than jumpers currently in use. It will cost money to buy, but much less than a lawsuit with injuries. I am old enough to remember the arguments against seat belts and yes, people still are telling us that smoking does not affect their health.
Let us as an industry take inspired, decisive, complete and pro-active action by making the time out jumper the only accepted jumper to use and avoid such incidents in the future.
I noted and can appreciate why the reference to jumpers on this job's reverse phase relays were removed. Too late, that baby was born and even an average insurance investigator will find out by deposition.

Elevator companys spend millions of dollars every year safety training on jumper use alone. And millions more desinging new less jumper dependant controllers and this is great and will obviously save lives and prevent injurys.But with 80% of the elevators out there at least 15 years old.And the current economic climate we will be working on older jumper dependant elevators for decades to come.
The Timeout Jumper is the answer for jumper left behind incidents. If a jumper is left behind by accident it opens up and becomes harmless. If one is left behind on purpose to engineer over time call backs that mechanic does so at the risk that their ID is on the jumper and they will have to answer for why it was left where it was. I guess unscrupulous mechanics have been under sizeing fuses and loosening stud connections for years but would they do the same if their name had to be left behind? Any tool can be misused but if we can save lives and prevent injury to people and property with the use of new technology are we not compelled to do so.
Thank you Robert for your support.
