Do you work with jackasses and drama queens?

A few days ago one of the boilers at work exploded. ...a little.
This isn't anything unusual, they do it once or twice a year.
The burners are old and in the last few years we've had to pipe exhaust gas back into the intake in order to meet the emissions standards.
(So basically we're pumping really hot, damp air into a fan that's built to just run cool dry air.)
The fans don't like this and show their disapproval by rusting, getting metal fatigue and eventually flying apart inside the burner casing.
It's a pretty exciting event. -Especially at about 2am when you're all alone and the coffee's got your nerves on edge.
It usually goes one of two ways:
The middle bands on the squirrel cage break, bowing one side of the wheel out. The burner just shakes itself apart if you don't get it shut down in time. -Which isn't easy, since it's programmed to purge(run the fan) for 1 minute after shutdown and the circuit breakers are in a panel behind a locked door.
-or-
The end bands break and the thing splits open and shatters against the casing with a BANG! and the motor arcs and catches fire. (There are heaters on the starter relay, but I have yet to see them work. There aren't any vibe sensors at all.)

Okay, so this has been going on for awhile and everybody's been told repeatedly to expect it and what to do when it happens.

BTW I have seniority(as if that meant anything)

I come in to work a few days ago and our newest member is sitting at the desk looking intense. I ask him why we're on a different boiler than normal and he tells me not to touch anything until the day shift gets in. I say "...er, what?" He says; "I called the sergeant and had him take a look at the boiler."
".....'kay."
"So.... what's wrong with the boiler?"
He told me that the boiler started shaking itself apart on him and he couldn't shut it down. He started in on the stop switch being bad and how he was reporting the company to OSHA, etc, etc.
He spent some time writing about this CATASTROPHIC FAILURE in the log book. -Liberally applying the highlighter pen.

The boiler WAS looking rough. There wasn't a tight screw left on it and some of the panels had come completely off. The burner body was two bolts away from falling completely off the boiler plate. (THAT would've been messy.)

As soon as I got him to calm down, I got a wrench and uncoupled the pilot so we could see the fan. All the while he's yelling at me to not touch it and wait for our boss to come and see it. I pull the pilot back, and sure enough, the two middle bands were broken and the fan was bowed out on one side.

So I try and tell him, "This isn't sabotage (you meep). Come look" But he wouldn't look at it and refused to listen as I told him for at least the third time that this is just the way things are.
Did I mention that this guy's 50-something, got an A&P certification and (I meep you not) is working on his doctorate?

Anyway, the day shift comes and of course the bosses look at it and go; "Okay. ...so what are we looking at?" so we sigh, rub our aching heads and send them back to their offices to sign important things.
The day shift puts a couple of screws back in, installs a new fan and (to be an meep) writes "EXHAUSTIVELY investigated #1 boiler for cause of CATASTROPHIC failure." in the log book. Then fires #1 right back up.

Of course, he forgets to replace the bolts that are HOLDING THE ENTIRE BURNER ON. So I spent the night replacing those and a bunch more. -The ignition transformer and the igniter solenoid were dangling by one screw each, etc.
Then I walk outside to get the cooling tower readings and I notice that the purge valve is stuck open again. I look and ...HOLY meep the cooling tower's almost empty!
I was a half hour or so away from a chiller failure from condenser water loss.

That assholes must have never took a reading, because you can't look at the guages without seeing the water level. And it takes about eight hours to drain those towers.

Of course I won't do anything but tell them about it calmly and ask them to please be aware.

This is why I have the rule. It's a simple one:
MAKE THE PLANT YOURS.
Screw the company, screw the coworkers, screw the guy in charge. They come and go. Be nice, but don't get involved with the petty meep.
Just keep the plant going. Look after it like you would your own child and no matter what happens, YOU DID YOUR JOB.
