I was taught to keep my hands at 10 and 2 while driving down the road. The intent of the rule is to maintain control of the vehicle in the event of a blowout or sudden emergency maneuver.
The observation that resulted in my warning letter was done in the parking lot of a Taco Bell while I was pulling out of a parking spot.
The ten and two "push pull" method of steering was written specifically to shield the company from liability for carpal-tunnel and other injuries that resulted from its business decision to delete power steering from its vehicles. The method simply shifts the responsibility for these injuries back onto the employee and relieves the company of any responsibility for solving the underlying problem.
The car I was in had power steering. There is no rational basis for using the push-pull method in a power-steering vehicle when turning the wheel 5 complete revolutions from one side to the other in order to maneuver out of a parking space. In the real word, nobody drives this way.
UPS is well aware of this fact but they cannot admit it; to do so would be to acknowledge that there is a difference between power and non-power steering vehicles in terms of injury risk, which would then require the company to spend $$ on fixing the unsafe equipment.
Based on your initial post ... I would whole-heartedly agree with you. However, there is always two sides to a story so I will refrain from passing judgment and validating your claim based solely on the post you wrote. We can't get the other side so this is all one sided.
Where it gets real interesting is the continued rant you go through. I highlighted the portion that I feel shows lack of credibility. A lot of your posts indicate you have some sort of "inside knowledge" of UPS subversive activity. You
always have the "smoking gun"! Again, this is where I take you to task. Many of your posts send completely invalid information out to others and because you sound so confident I am sure there are those who hang on your every word. I happen to know better.
As for the 10-2 position on the steering wheel....
In the real world .... I use it most of the time in my personal cars.... and I use it pulling in and out of parking stalls. I went to feeder school, and this is where I picked up the habit. I have more strenght and control of the steering wheel when I use this method and I can make small adjustments when parking much easier and faster.
You only have to go so far as to look at the tires of a commercial vehicle. Most commercial tires have at least 6 to eight inches (or more) of clearance from the rim to the ground. If you have a sudden blowout and your hands are in the 10-2 position with THUMBS pushing parallel on the steering wheel (not wrapped under the steering wheel) you have the best opportunity to maintain control of the vehicle. If you have a blow out, the steering wheel will rapidly drop 6 to 8 inches in the direction of the blowout. In some cases, it has snapped the thumb because the column catches it.
This is why UPS adheres to this rule ... not the absurd conspiracy theory you put out there!
Sober - There are a lot of times that I understand and can agree with you but as I have told you before.... if I see these off the wall conspiracy theory rants that you insist are fact, I will call you on them every time.
Anywho, I work safe because I have an active lifestyle away from my active job and I don`t need to limp around. I drive safe because UPS makes me drive a vehicle that catches the wind, can easily roll over and has open doors; I fear for my life and don`t want to die or get maimed! It is also very funny in the morning having an out of shape supe that can`t touch his toes have us do 30 seconds of "stretching" to "get us limber" after I had just spent an hour in a half at the fitness club before work because I , without supe help, know what I have to do to prepare myself for my job!
