Working with a pressurized tanker trailer

And when you do open the manlid, obviously make sure it’s depressurized, and leave the last 2 wing bolts on the opposite side of the hinge the last to unscrew.

 

1 PSIG = 100# of force.

Trying to close a partially open hose ear under pressure is JUST as dangerous.

While blowing off a loaded bulker, the driver reached up with his rubber hammer to push the ear fully closed on the 6" cap on the fill pipe.

They found the cap in a back yard about 1/2 mile away...

Liquid air pressure discharge challenge, blowing plasticizer in to a bottom fill with no check valve...

 

Wow, that was crazy, that guy was VERY lucky to walk away.

 

Same here. In fact, my boots don't leave the ground unless the tank gauge is at zero with the blowdown valve open. That's the only time when I know it's safe for me to be away from the controls.

No way in hell would I ever get on top of a trailer that was under pressure.

 

If you haul crude oil and pressurize the tanker (don’t have your vent open when loading) and try that pressure release valve at the top of the tanker you’re more than likely going to make a mess. Particulate oil will spray out with the pressure release and dribble down the side of the tanker. We had a nepotism hire several years back who gave a great education in “I wonder what would happen if” scenarios.

I buy my own cam locks. For some reason none of the companies I’ve worked with ever supplied them. Better safe than sorry.
