Thanks for the reminder, we all need this from time to time.

Any piece of equipment can fail without warning. Safety back-ups are needed. I once was jacking up a very large '72 Chevrolet wagon with its bumper jack. The "hook" on the jack where it hooked on to the bumper just broke off and down came the car. Then I went in and changed my shorts.

At a high school auto shop class where I worked, They had a car fall sideways off the hoist down to the floor! No one hurt but it sure didn't do the car any good!

How you use the equipment is just as important. More than once I've run my Volvo up on ramps to change the oil and found the front tires half on and half off the ramp. Sometimes it has taken me a few tries to get that car on square.

I once saw two guys under a car with the car sitting on cinder blocks!

I used to be the safety officer for a school district. The biggest safety problem was folks not taking the time to do something right, cutting corners, being in too much of a hurry to take safety precautions. We had a lovely young woman on a painting crew fall when a ladder came down. She will be in a wheelchair the rest of her life. It would have taken only a few minutes to tie off that ladder so it wouldn't slip! It's been many years now but that still haunts me.

Take care.
