Author Topic: What are you wearing...when you change Xenon lamps.

Something that I had to do when I used to work for a flake of a company a good dozen years back. They had old CH-20 consoles with all of the failsafes disabled - switches all removed and the loose wired ends wirenutted to complete the circuit. Thus, you had to open the door with the bulb lit to do the azmuith and focus since all of the controls for such didn't work when using the allen screwdriver.. ..and no safety gear to be found. The owners didn't even blink an eyelash, or showed any concern for employee safety - you hurt yourself, it was your fault in the first place in not being careful.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 06-21-2011 07:31 AM                     There have been many times especially on CFS and ORC consoles and even some of the 15K water cooled one one needs to go inside with it lit  |  IP: Logged Manny Knowles "What are these things and WHY are they BLUE???"

What are you using? I wanna know!  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 02-06-2012 03:22 PM                        I wear shoes when changing bulbs!

Most of the ballastic jackets (and especially the gloves) would restrict movement so much I felt the risk of hitting the reflector or dropping the bulb was greater with the gear than without. With the CP2210 the working space is so tight I wore the full gear set and sweated a lot.

But really if the lamp goes off in my hands the shield ain't stopping shit. But its the thought that really matters.  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 02-07-2012 02:24 PM                     Chris, when Edward posted that I was thinking the same thing. For those who have never worked on a Christie, that lamphouse is a lot tighter than the pic makes it look. That vented bulkhead on the left forces you to put the bulb in at a very steep angle, the cathode end WILL hit the reflector no matter how careful you are, and if you have big hands like I do it is hard to get your fingers in the rear of the reflector to grab that cathode end to thread it through the hole. And I was using the 1.4k bulb!! (I don't know if the higher wattage bulbs are any longer, but even a few millimeters would make it even harder.) But that projector really knows how to throw out the light! Manny: Never have and never will use or need a torque wrench on a lamp change. I just use the German method of making all connections "gutentight".  |  IP: Logged Jeff Taylor Jedi Master Film Handler Posts: 601 From: Chatham, NJ/East Hampton, NY Registered: Apr 2000 posted 02-07-2012 03:21 PM                     I know it's not kosher, and I do use gloves and eye protection even though I can't see what I'm doing, but I just keep way off to the side with my body out of the way and do it by "feel". So far so good. I suppose if I ever changed one and it didn't work (well, that actually happened once, but it was a dud lamp) I'd have to suit up and take a more conventional approach. Not advocating anything--that's just what I do.  |  IP: Logged Graham Ritchie Film Handler Posts: 54 From: Christchurch, New Zealand Registered: Apr 2009 posted 02-07-2012 09:40 PM                     Faceshield, leather jacket that also covers your throat and gloves. In the twelve years of projecting we have had only two lamps that went "BOOM" the lamps were fairly new and were both "Osram" 1600watt and 2000watt "XL" fitted in different projectors. our... "Boom".... photos mirror was damaged and needed to be replaced, looking at what that lamp did to the mirror is one "very good reason" not to be working close to lamp thats going without wearing full safety gear. In general most lamps are fine but you dont want to be "sitting duck" if and when that once in a lifetime faulty lamp goes...."BOOM" not much left of a $800 dollar lamp. On the safety side you need to cover your neck, all it needs is a piece of glass from an exploding lamp to hit you on your jugular and you are history for this world.

Posts: 4247 From: Bloomington, IN, USA Registered: Feb 2002 posted 02-08-2012 04:59 PM                     Okay, thanks for all the input. Since I started this, I guess it's only good manners to provide an update. I ordered a Welder's jacket (leather) from Grainger, a 3M face shield (ANSI Z87.1 compliant), safety glasses and gloves from local hardware stores. I'm going to try again with the gloves though - I want my wrists completely covered and these aren't doing it for me. ...and BTW if you want the sexy groin protection, I found where my old ballistic jacket came from... Christie Lamp Safety Kit Part Number 598900-095-XX Sigh... I wish I'd stumbled onto that link before I bought the welder's jacket! Torque Wrench - Tohnichi QL25N Torque Driver - Tohnichi RTD500CN  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 02-08-2012 05:56 PM                     quote: Manny Knowles Torque Wrench - Tohnichi QL25N Torque Driver - Tohnichi RTD500CN Manny, Manny, Manny, must I repeat myself? You DO NOT need a torque wrench for ANY reason, any lamphouse!! I speak from over thirty years of tech experience on virtually every lamphouse ever made. Just make sure your connections are clean and "gutentight" like a German virgin and you will NEVER have an issue. There are better things to spend money on than a tool that is totally unnecessary for what you are trying to do. Graham: Not to undermine the importance of your post, but the difference between a bulb that fails while hot/operating is many orders of magnitude greater than a bulb that is cold or being installed. The carnage you showed is very typical of an in-operation failure. Little known fact: Some lower wattage bulbs operate at a HIGHER cold pressure (500 watt bulbs are especially high pressure) so a cold failure with them is MORE dangerous than that of a higher wattage (say 2k) bulb. I found out the hard way when I had a 500w Osram explode on me during handling..even in the protective cover it shot glass dust everywhere.  |  IP: Logged
