I rarely dip into these waters but here's my two n six pennorths. In my world Personal Protective Equipment and safety measures are a constant fact of life. I am amazed that with the type of gear that's readily available, which costs in airline terms peanuts, that this kind of thing is still going on. Fall restraint harnesses which are built into jackets and take as long to put on have been on the market for years now. As for steps, platforms etc a simple interlock system that cuts the ignition if the vehicle is moved without a bar or tape being closed at the working end would not cost that much to install.
But I guess life and limb still figure low with the blunties and bean counters.
I hope the CC involved makes a full recovery and the rest of you take care now.
