Again, please don't misunderstand me. I do not think safety is pointless. But from where I'm coming from, in my opinion, it doesn't present a significant risk. I am merely disappointed that the other operators don't see it that way. It was determined that this is not a decision that should be made for them, however, and we've decided to go ahead and not run the machine at all.
The problem is with the definition of "significant risk." You say the risk is insignificant because it's unlikely that the bulb will blow. But if something bad did happen, there would be SIGNIFICANT damage (both to people and the equipment nearby).
But as was mentioned, just detaching the blower stack from the unit will probably let quite a bit of the hot air out. Anyone knows that hot air rises. So some of it will tend to shoot up simply from convection. Plus, inside the lamphouse the air pressure will be much higher than outside which will cause the air to tend to go out any opening.
You should definitely try that before doing anything more involved, especially if your lamphouse sucks in cool air from a lower section than where the hot air will be let out.
Like if you had some way of measuring the temp of a bulb, light a similarly lamp (same model lamphouse and same wattage) and see what it runs at. Then test the temp of the lamp that's got the stack pulled off. If it stays in a similar temp, you'll be ok. And it'll be safe/cheap.

If the lamp explodes, it could cost you a couple-three thousand dollars to repair the damage, whether the covers are on or whether the blowers are all working or not.
If a lamp explodes and the schrapnel hits a person, he or she will, AT MINIMUM, need to go the emergency room for stitches. If glass hits them in the face or if a large chunk of the lamp hits them in a vital area, they will end up being admitted to the hospital if not maimed or killed.
Now, let's assume that the lamp has the same chances of exploding whether the covers are all closed or not. Even if it's only a 0.001% chance, why would you want to risk hurting somebody?
It's just really simple to keep the covers on and cover your ass in the mean time.
What about the "numbers game"? How does management think it's saving money? If the lamp explodes, it will COST them LOTS more money than taking this chance saves them.
If that lamp goes, the projector will be out of commission until it is repaired. You will lose no less than one or two shows. Refunding a house full of customers on a Saturday night is going to cost you plenty! If the explosion puts you out of commission for a day or more, you will lost THOUSANDS and THOUSANDS of dollars! FAR more than the few bucks you saved by not paying for the repairs you need in the first place.
I understand the drive to keep the projector on-screen. It's a matter of pride and concern for your craft. "The show must go on!"
Virtually every one of us agrees that you could do those things to save a show. But, virtually every one of us ALSO agrees they this should never be done for anything other than a Band-Aid measure to get you through until the repair man can come.
The law of large numbers is working against you. You might not have a catastrophe THIS time but the consequences of a catastrophe are often so great that you can't afford to have even ONE.
Don't take chances. Don't roll the dice.

talk about cheap and stupid in someone digging up used HTP bulbs to burn in this STRONG lamphouse...( I don't know how they managed to burn these wrong bulbs in that lamphouse, but was told that it was somehow done by their so-called technician -which I really don't want to know how it was connected..)
