A 37-year-old man was killed Tuesday afternoon when a vehicle he was working on fell on him.

Police were called to the manís home on McEastern Path, in Milton, just after noon.

The victimís name has not been released at the request of the family

I have a feeling something else happened. Maybe the vehicle rolled back or the jack stands could have not been strong enough for the vehicle. Race ramps may be a good alternative for stuff that doesn't require the wheels coming off.

Its hard to find a decent jack for under 200.00 these days. Try reading the reviews of jacks on Amazon. Many (if not most) of the jacks are plagued with hydraulic issues.

Assuming a shear strength that is 75% of the ultimate tensile strength, and also assuming it being A36 steel (the most common grade around) at its lowest UST, we have 58 kPSI * .75 = 48.5 kPSI in shear. With a safety factor of 4 and a 3400 pound car that equals a load of 13600 pounds. 13.6/48.5 equals a .2804 in^2 pin to support the entire car with a 4X safety factor. That equates to a single pin with a R.2988*2=ō.5976 to support the vehicle (with a 4X safety factor!!!.

I think there's more to this story than meets the eye.

I wouldn't be any more afraid of using jack stands than I would be a lift (which use pins as a safety mechanism)

A jack is not a jack stand. ALWAYS use a jack stand.

Yep. But it's still hard to trust jack stands...the guy died using a jack stand.

Hopefully the entire car wasn't being supported by 1 stand...

One stand would have supported the car without any issue. I'm sure negligent use of the equipment is the more likely cause, or, if the equipment was defective, a manufacturing defect to which all products are susceptible. Lifts, ramps, jacks, jack stands, cranes, etc, etc.

This is something I fear and the reason why I won't be DIY things that require lifting the car up.

Not true, you can pickup a very well made Arcan 3.5ton low-profile jack from Costco for $99.

Read the reviews for youself online, do quick google search of the terms: costco jack, costco jack arcan.

The benefit from buying from costco as well, is if for say the jack every leaks you could roll it back into the store without its box or anything and get a full refund. Even years after its been purchased, this is possible with Costco's amazing purchase protection.

If its sitting on a jack, have a jackstand sitting under as well. If its sitting on a jack stand, have a block of wood sitting under as well.

Ugh...probably time to get a second set for some redundancy. As someone new to this, I'm definitely scared about doing something wrong. A lift will be in order once I buy my first house.

I've used my bent spare rim to support my car when I had no jack stands available. I will trust a jack stand or something very similar than just a jack lift. I've had the awesome experience of a 65,000lb truck fall 1" from my face in Afghanistan while I was under it with a bottle jack (yes they make them that big).

Something negligent or manufactures defect had to have happened. I don't see how something as simple as a jack stand just arbitrarily went wrong.

I think the article is mistaken a jack with a jack stand. A jack stand can't fall. He probably used a jack and went under it. I've attached a pic of a jack stand and I don't see how it can fail.

Well, maybe the stand was poor quality and failed. Maybe it was not properly installed and tilted. Maybe the car was not level and jumped out of the jack. Maybe the locking handle was not fully at rest and the top stand collapsed. Maybe it was installed under a non-structural part of the car and the car itself bent out of the stand. No details, hard to know.

Bottom line, this happens very rarely, and outside of operator error it's even more rare. Unlike hydraulic failure of jacks which are very common and to be expected, this is a freak event.

Careful with some brands of ramps. They are known to collapse too, quite often, at that. Do not trust cinder blocks or wood stacks either.

Yea, agreed with above, it's not clear exactly what type of jack the article was referring to. Could have been a hydraulic jack, or worse, the one that comes with the spare tire kit in the car. Seems pretty improbable it was the jack stand as pictured above, the liability there would just be insane if that's in fact what happened.
