We’ve been inspected by a few of the Kodak guys. None have worn guards or gloves or body gear when inspecting the lamphouse.Having said that, they do it before the lamp is struck for the first time in the day, so there is no chance of the lamp being warm. It’s highly unlikely that a cold lamp should burst just because the door has been opened. They don’t “poke about” as you suggest, merely examine with their torches. Still, I think we should all stick to the “If you don’t have protection, don’t enter” school of thought. Not just in the projection room. ![](http://www.film-tech.com/ubb/wink.gif) If your employer supplies you with masks, gloves etc, USE THEM. If they don’t, either demand that they do or refuse to do that task.

(i) Lamps can explode when they're stone cold. It happened to me while I was removing one for replacement (I'd left it overnight as a safety precaution). OK the lamp in question was previously heat damaged from having been overrun, but surely it would be possible for an inspector to find a situation like that on a site visit. If I hadn't been wearing a visor, jacket and gloves whilst handling that lamp I don't think I'd be here writing this message.(ii) I wasn't suggesting that the Screencheck engineer would 'poke about'. The point I was trying to make is something like this. Some arts centre or community theatre shows films once or twice a month. The A/V technician runs them, whose only projectionist training is having been taught to lace up and do changeovers. One day the Kodak literature arrives in the post with that picture in it. This gives him or her the idea 'Hmm, the bulb has been a bit flickery for a while, let's open up the lamphouse and see if I can find anything obviously wrong'. While looking, the bulb explodes in his or her face. I've worked in one or two of these places where they really didn't have a clue as to how dangerous xenon lamps can be, and it is for that reason I thought that publishing this photo was a bad idea, even if it does show an empty lamphouse. As for beards, you wouldn't need to digitally add or remove them after a few lamp blowups. Nature would have done something just as impressive!

I quickly got a copy of the brochure (actually a reprint of an article in the March 2001 issue of BKSTS "Cinema Technology"). Page 4 of the brochure has an excerpt from the Kodak ScreenCheck procedure manual (which I wrote) which CLEARLY says:"Using proper safety equipment and procedures (turn off power supplies, use Xenon lamp safety equipment), have operator open up the lamphouse. Examine condition of lamp, reflector, wiring, etc." I believe the engineer pictured is Richard Boaste, one of the ScreenCheck Auditors for the UK. I can only assume the distraction of having a photographer tagging along on the inspection of the Salisbury Odeon led to a momentary lapse in proper safety procedures. I will reinforce the need for proper safety equipment. Overall, the BKSTS author Jim Slater was impressed with the comprehensive Kodak ScreenCheck certification. ------------------ John P.

I checked with Denis Kelly, Manager of the Kodak ScreenCheck program for Europe. He indicated that the photo in question was indeed taken AFTER the xenon lamp had been safely removed from the lamphouse. It was felt that taking the photo without the "Iron Giant" safety equipment made for a clearer illustration. Ironically, at the time, the participants thought there might be some misinterpretation. In hindsight, they should have shown the use of the proper safety equipment.------------------ John P.

Leo, A stone cold Xenon has 2 pounds of pressure in it, that is around the same as a hot fluo. If you had a stone cold (24 hours no less)xenon explode on you while removing it, I suggest you review how much care you were taking while removing it.My freind, Im not having a go but, I've been in this game since 1978, and have removed bulbs that were damned HOT (with gear on) in the middle of a show, and never had one explode. You mentioned it was beyond its useful life. Perhaps that explains things. Tell your M1 you need a need bulb before you have to wait 24 hours cooling to remove it. You should have at least 2 spares on hand. Change as required, then inform H/O you need a new bulb. Perhaps you were just unlucky, but the best part is that you were wearing protective gear that saved you you from harm. I'm done with dragging out bulbs as long as can, giving the patrons a crap flicking (cylcing) picture, I just order new bulbs. Regards Bill. Supply and demand might bring the price down? Who knows.

Quick note When I say, 'In the miidle of a show' I mean, shutting down, waiting 10 minutes for bulb to cool, then removing /raising lamphouse door, directing room fan towards lamphouse for 5 minutes, then moving in to remove bulb with FULL gear on. This is scarey..However you can take MORE time, it just depends on how you explain the situation to your patrons.. are they willing to wait longer or will they rather come back the next day. THIS IS DANGEROUS Those of you who just finshed making your last choc-top should not attempt this.
