compressor exploded- lost leg
Locally, 3 guys were restoring a car this wknd when the compressor exploded. One lost his leg at the knee, other had head injury, third was in hospital for observation. Appears that the tank was rusted.
Thought I'd pass this along for anyone with an old compressor to think about.

I'll be saying a prayer for these guys also.
The main reason rust accumulates in a tank is because the air, which has a lot of moisture in it, is not bled off each day. Bleed the air off and notice how much water comes out with the air.

Thanks for the reminder. I have a compressor at my shop and haven't bled it for months. I'm don't have an automotive shop but it comes in handy cleaning dust of small parts.

my compressor is in a seprate shed next to the shop. mainly for niose.
at the truck shop I used to work at, there was a line that ran out back to a small box , it would spew off air and water ever few minutes. kept the shop air pretty dry.

I had an 8 year old air compressor that I didn't drain as often as I should have. One day I pumped it up and it had a hiss. Rust hole in the bottom, next to the drain valve. Somewhat expensive lesson to drain it after each use.

sad to hear but it will make us all conscious of the dangers we sometimes take for granted.if you are like me and work alone you are even more susceptible.be careful out there fellow c3'ers.

Mine was difficult to open and was just a cheap valve like on a radiator (which is not meant to open regularly) had to lift the thing up and open it. So I took the valve out and put an elbow to a nice quality easy to open and close valve sticking out the side bottom. Reach down, open/close.

Sad indeed; we've lost a fellow car guy.
All commercial pressure tanks (over a certain size) require annual inspections and regular recertifications, but, personal tanks not at all. I built a home made air compressor as a teen out of a tank I found in a scrap yard. I know for a fact that a friend of my dad's still has it in his barn for the tractor. That tank must be 50 years old by now; who knows whats inside?!

I'm guessing that it wasn't a rusty tank that caused the explosion but something in the pressure regulator system. If there was a weak spot in the tank it would probably just blow out like a tire and lose pressure. Over-pressurizing a tank past its rating turns it into a bomb.

Sorry to hear about those guys. Also don't forget to be careful when pumping up tyres, they can do you a serious mischief if they blow.
Bought a Chinese made compressor recently, it had a certificate plate on the tank and all. First time I started it up I could hear a hissing noise that was not coming from the outlet. I found a defect in a weld in the tank that was leaking. So much for certification, I bet they just weld the labels on as they build the tanks. FWIW if you are looking for a strong tank to use for a compressor you will find it hard to get a stronger one than what is used on railway rolling stock:-)

Something else was in the mixed, when a tank fail it usually rupture... something must have been propelled to cause a leg injury. Proper storage is something we don't necessarily think of when placing a compressor in our garage/shop.

EDIT: Another note - people should use the minimum pressure required for the task they are performing. People tend to leave their PCV at a fixed (high) point when they do not need such a high pressure.

All kinds of tools can turn dangerous without proper use or care. RIP to the car guy who passed.
Compressor tanks are always a concern if not drained periodically. Even though it is too dang cold here today, I'm going out to the shop and perform draining and greatly reducing the stored pressure.
Preventative maintenance takes on a higher level of awareness. Stay safe out there.
