That being said, the kill switch in the lamp base for those units seems to be fairly well-engineered. It's a simple spring-type contact that closes when it's depressed by a post on the instrument housing. When I had them, it never even occurred to me to worry about its durability, for two reasons: the simplicity of design makes it extremely reliable and does not subject it to unwanted misdirected forces (the contact is recessed inside the base, so inadvertent contact is pretty well impossible from any direction), and the readily apparent level of thought and planning and care that went into the rest of the instrument resulted in a luminaire of very impressive overall quality. I can't imagine that they'd have reinvented the wheel for the fresnel lines, so if you find that the design is similar to what I describe above, your level of concern should drop substantially. As for the gel frame holders...I know what you mean, but I think that impression is more a function of the use of aluminum for the housing rather than steel. The finish is deceptive to the touch in a way...if you run you fingers over the frame holders, I'll admit that they do feel a little short of beef. But in a couple years of constant use I'd never run into so much as even a chip. While I can't in good conscience completely endorse the whole of their product line (because of my limited experience with them), it goes without saying that I absolutely love the Pacific line of ellipsoidals; and if the manufacturing quality along the whole of their product line is fairly consistent, I'd wager dollars to donuts (or beer to donuts, if you prefer) that you'll end up pretty happy with them. The ONLY complaint I had about them (and checking the PDF for the instrument I think you're thinking about confirms this is the case here too) is that the color frame size is slightly different from the old Altman sizes...in this case, 7-3/8" square. So you'll have to find some way of keeping the gel frames separated in storage lest you try to gel a whole lotta instruments and have to grumble and swear when you try to stick a 7-1/2" frame in one of these. ------------------------------ Subject: Field Service Job Opening Date: Fri, 16 Sep 2005 09:39:33 -0400 Message-ID: From: "Paul Sanow" Please excuse this short semi-commercial announcement.

I little on the dinky ide >(compared to the nice beefy ones on the colourtran or >ETC units. Have they failed anyone? I think the frame holders fall into three catagories 1) formed metal -- like Altman 360Q's, you just bend them back into place with a wrench, ~$0 USD 2) cast and attached -- the CT Fresnels holders break and you replace them with a couple of screws, ~$7 USD 3) a larger cast assembly -- like S4's or old Strand-Century, when the holders break you have to buy a new half-of-a-lens-tube or something. ~$25 USD I don't know the Selecon unit of which you speak, but if the performance is far superior than others then buy a bunch and don't worry about it; maintenance will be what it is. If the light is somewhat better than a fixture you already know and have in stock, get more of the same; this leads to fewer parts to keep on hand, fewer styles of lamps, and not having to learn how to repair a new fixture. Also, IMHO, it is far easier on everyone (house and end user alike) to have a compact inventory list, like 150 Selecon Arena Fresnels than it is to have a handful or two of 4, 5, or 6 different kinds of Fresnels Paul __________________________________________________ Do You Yahoo!?

Anyway, in regard to the paint, we were told that "water based paints were okay, and oil based paints belonged in the cabinet." Seems fairly simplistic, but thus far it's worked for us. In the area of disposal, etc, that is handled by the college's Buildings and Grounds department. They have procedures for disposing of paint, storing, etc., so a simple call to them often takes care of an overabundance of paint. They have also provided me with the necessary fire codes in the past, and a place for students to "appropriately use spray paint." You might want to try giving your maintenance facility a call.

Check the MSDS for the paint. If it says it is flammable then it goes into the flammable cabinet. Don't store other stuff in your flammable cabinet, it isn't designed for it, and you may be unknowingly creating a bomb. Latex paints are water solvent mixes, so they are not really flammable liquids, but they will burn once the water is boiled off. I was visiting someone's home once, and noticed that he had a nice flammable liquids cabinet in his garage. He was also using the cabinet to store his pool chlorine powder and chemicals, and his industrial sized container of Drain-O. I suggested that it wouldn't take much of an impact of the cabinet from his kid who was getting a learner's permit to turn that into a nice firebomb. --Dale ------------------------------ From: "Steve Jones" Subject: Financial managment software...

But this brings up a good point. We use a multiplicity of chemicals in the theatre. Some of them don't play well with each other. For instance, bleach and ammonia. Should those chemicals be stored in a flammables cabinet? Can they be stored in the same cabinet? (My gut says "No".) In an article in the ACTS FACTS newsletter edited by Monona Rossol, dated February 2004, Vol.18, #2, it was discovered that prussion blue and chrome yellow or chrome green dyes should not be stored together. Both off-gas and the combination of those compounds can ignite spontaneously. Who knew? When we built our theatre building in 1996/97, we had a room designated a Paint Room. Because it had that name, the local AHJ (authority having jurisdiction) specified that the room be an explosion proof room. Four hour walls, two hour doors, explosion proof light fixture, no outlets in the room, etc. (Of course, the A/C vent leads to the men's bathroom, but I guess that really doesn't matter.)

The problem this creates is when the line-set is at pipe-weight and the pipe is all the way in(arbor at its upper limit) the loader is unable to reach the bottom o= f the arbor from the loading bridge to load it safely. The solution that has been developed is to fill the bottom of the arbor with home-made Styrofoam stage weights. These are made of polystyrene =B3blue-foam=B2 and are placed in the bottom of the arbor, on top of the pipe weight. The loader then loads the appropriate weight for the load hung on the pipe on top of the foam bricks and it is used in this manner. This is where my questions come in. 1. Is this solution safe? 2.

If you have even an ounce of a flammable item such as varnish, spray paints, even Tester's enamel (good for touching up dings on grand pianos), you are REQUIRED to have a flammables cabinet and that the appropriate items are kept there, under RCNY regulations. In addition, OSHA can fine you for having flammables exposed (that aren't currently in use) and/or that are handled incorrectly. Your flammables cabinet must be of regulation colors -- either red or yellow, with some very specific size and location to the label on such cabinet. The cabinet cannot be located next to a heat source, must be securely mounted if not on a flat, solid surface (I guess some people have gravel floors in their paint shops?) and be of an appropriate size, by which is meant that cabinets of certain sizes are meant to hold x number of gallons of flammable paints and volatile substances and even though they'll hold many more -- you have to have a second cabinet for any flammables in excess of the first cabinet's rated capacity. The cabinet must be noted on groundplans in the building manager's office or whatever the firemen are going to be needing when they come to fight a fire. You MUST have a complete and accurate listing of the contents, ready to be handed to firefighters. MSDS for all stored items must be readily available, which is an OSHA requirement anyway - I kept ours in a binder underneath the first aid kit, which was by the shop phone, which was next to a list of emergency contact names and numbers, which was above the eye-and-ear-protection rack. You can look up all the specifics in the Rules of the City of New York, which is not a cheap publication, but thankfully you can subscribe to only the volumes you need. None of it is odious to comply with; only sounds like it. Now is a good time to teach your students the value and pleasure of "cleaning as you go" and of keeping inventories up-to-date and what MSDS are all about. I simply made it a policy that our shops won't use anything but latex paint and water-borne gloss coats, made easy by using Rosco paints, of course. Still... We had a pretty full flammables cabinet because of the various items you tend to need a little of over the years: varnishes, shellacs, paint thinners, isopropyl alcohol, hairspray, Tester's paint, lamp dip, stains, etc. Latex paint is not flammable; can and should be stored separately. It is, however, considered a "hazardous substance" by the EPA and thus must be stored in tightly sealed containers. Dented that 1-gallon cans rim accidently? Pour the remaining paint into an undamaged can so that the lid will seal correctly. Now is a good time to teach your students the uses of a rubber mallet with a light touch and what a church key is for. Disposal of excess latex paint CANNOT be down the drain anymore. You must have a suitable disposal container (ours was a fancy-schmancy 50-gallon rig) and said container must sit in/on a device intended for spill capture and which must be able to also handle the entire contents of the disposal container (ours was essentially a plastic shipping flat kind of thing / shallow basin, with a bladder that would automatically unroll as it filled should worse come to worse). Alternatively, you may simply let your excess latex paint dry out in the cans and call your hazardous materials handling team to come pick it up. Not that it's hazardous at that point, but EPA regs are what they are. Copier toner cartidges and discarded flourescent lamps are also EPA / hazmat domain. I can't address the wood situation. By reason of lack of shop space, I kept our scrap piles low and by reason of anal retentiveness, I made sure the shop got swept and all sawdust thrown out daily during build periods. Stored sheet goods...I never got hassled about those except when they blocked access to the twin 500-gallon hot water tanks in the ceiling of the shop. Hope this helps. Really, you should have copies of the OSHA manuals, the applicable RCNY volumes, and your own insitutions policies all in a neat row on your shelf, dogeared and bookmarked.

After playing around with them for awhile, I got pretty comfortable with the concept. The blueboard resists compression extremely well. Take a look at the stacks, you will see that the bricks are in pretty good shape. Here at UNCG they filled the extra height with plywood cut to stageweight shape, which added a lot weight to the arbors. Of course they didn't compensate by removing any pipe weight that was on the arbor to begin with. Yet another item on the to do list here.

I'd be happy if the candy-bar vending machine at teh venue I'm at would take small change. Presently, it'll take fivers, and give out change in quarters, which it won't take back. Occasionally, it'll take ones. They stock it with quarters so that it'll still take the fives... I think that this might be a local solution, as there might be three or four venues in any major city that'd be appropriate, and having a network to maintain and stock a few hundred machines across the nation would be more expensive than most folk would consider paying. Theatrical people are pretty resourcefull, and will find a way around a solution rather than pay twice what the real solution should cost, as we've all seen! Finding a used vending machine, learning how to program it for prices, painting your theatre or personal logo on it, and printing directions to the nearest ATM on the front might be a good thing, though.

(I have the dubious honor of sharing my shop space with the maintained staff who don't believe in "cleaning up"- but that's a b*tch for another day- like when's the last time you saw your Dewalt Table saw being used as a work table to take apart a weed whacker and then all the parts left laying on the table as it was time to go home. The saw was used as a table because all the other work tables in the shop had half-finished projects covering them.....) Thanks to all for your replies and FYI: Kristie- a small (about 8 gallon) Flammable storage Cabinet prices at close to $300, one large enough for my inventory would run close to $1K. No I am not arguing their value for true flammables but they are not cheap for storing relatively benign Latex Paint. And there are already two flammable cabinets in the shop area- the maintenance dept. are simply too lazy/uncaring/stoopid to properly put their stuff away (except for their personal hand tools, of course) Stephen: You had the wrong ass-u-mtion. As a small Comm. College there is no money for something as "needless" as a Health and Safety Officer. -Yes I am being facetious- If the PTB get 'scared" by a report like this it's up to the individual departments to respond with their own fact finding or monies. And yes the new NYS Fire Inspectors are a "joy". Who would have thought that it is against code for faculty to chock open their office door..... Tom D- thanks for your well thought out reply- I will definitely check out what is on the shelves and I like the labeling of "non-flammable liquids" only. And yes the inspectors have an important function but as much as I believe and adhere to safety practices, sometimes "a belt and suspenders" are not really needed.

When I was involved, some years ago, with the design of a broadcast quality disco, I ran into one professional DJ who drove his headphones from a 50W stereo amplifier. Needless to say, they didn't last long. Neither, I imagine, did his hearing. My own headphones are very sensitive. I can hear 1KHz tone at a level of well under 1mV on them.

Not "Calcium Hypochlorite". I can't say what's in other brands' bottles, but that's what's in Clorox Bleach. A quick Google for "Clorox and ammonia" brought up several references to not mixing them. Then I Googled for "Clorox MSDS", which brought up a number of hits, including this one: , which is on Gordon Food Services web site, and is a scan of the MSDS for Clorox. Under the "Special Precautions" section, it specifically says not to mix with ammonia-containing products, among others. The Centers for Disease Control also has some information at , including the following quotes: "Sodium hypochlorite solutions can liberate dangerous amounts of chlorine or chloramine if mixed with acids or ammonia" and "Odor may not provide an adequate warning of hazardous concentrations." Sounds like a hazardous reaction to me! On a personal note, my wife, a little over a year ago, decided to clean a section of our basement floor that was in serious need of cleaning, partially due to our cats missing their litter boxes in that area. Unfortunately, cat urine is a really good source of ammonia, and my wife had not remembered that little detail, and decided to use Clorox bleach to clean the floor. Lucky she realized something was wrong when she started to feel light-headed, and proceeded to get our daughters out of the house. She called me at work, and I came home, put on my respirator (which says it can handle the chlorine gas), opened every window in the house and set up several fans. At one point, while in the basement working on nutralizing the problem with water to dilute what was still on the floor, I accidentally dislodged my respirator and got a whiff of the chlorine gas that had been generated. Not a good thing to be inhaling, somewhat more than "mildly unpleasant", so I was a little more careful with my respirator after that. After airing out the house overnight, things were OK again, but a very valuable lesson was learned. Please refrain from telling me that bleach and ammonia don't react. And, to keep on-topic with the original discussion, unless you can guarantee that the containers of bleach and ammonia won't spill & mix, I would avoid storing them closely together.

Good question Steve L. I worried about that in the early going. On the the arbors we use - Clancy 15 series - we'd get about 250# per foot of 6" pigs (all steel, no lead). Using about 2 feet for the foam and pipe weight. This gives me about 1250# max. on the arbor. This allows about 1 foot at the top for slipping on the last pig - you loose about a foot for the angle the weight has to be at to engage the rods. In just about all instances, this offers sufficient capacity for even the heaviest stuff we fly. We have however been known to marry pipes for really big elements splitting the load over a couple of arbors. I am really hard pressed to think of an instance where we had to lay on our stomachs and reach down below the loading floor to load weight to get enough capacity. I do have access to lead pigs is necessary but have not needed them so far - about 15 years since the 8" arbors went in. This has worked for us very well, but others mileage will probably vary.

We made it rain over the full width of the stage (39' proscenium opening) for a depth of about 15'. We took our masonite covered (sprung) floor and used jaxsan to "waterproof it" --yes it worked, at least for the three weeks of tech/dress rehearsal and run -- remember Grapes has a truck moving all over the floor -- We minimized the amount of water we dropped during the approx. 15 minute scene. We used low flow misting heads (the kind you desert dwellers in Ariz use to cool the patio--flow rates measured in gals per hour not g/min) over the whole rain area to give the effect of rain throughout the scene. At the begining and the end of the scene we had higher flow rate (but still very low) heads to help establish the rain. These were low flow garden/greenhouse variety. This was all supplied via a standard hose bib and garden hose from the janitors closet . We have enough pressure here to get the water up to the 35' the heads were at with no problem. Garden hose broke out to smaller supply lines and manifolds made from our quick fit fittings and lines we normally use for air devices. Our calculations showed we dropped less than five gallons. Scene is near the end of the play. Water remained on the stage (we had built low barriers to keep it from running offstage or into the audience). After audience was gone we sucked up the water with housekeeping's commercial floor scrubber. Plumbing supplies from McMaster Carr. Low flow heads from elsewhere. Lights and sound did the rest. What was most effective for the audience was the "smell" of rain, the drop in temperature and the breeze that began as soon as the rain started to fall. It was just like---rain. Kind of a pain (we really couldn't test out the system except in place on stage) but not really very complicated or costly considering the effect.

Myself, I listen out there, and then set the level to give the same subjective experience. Maybe I turn the wick down a bit for my comfort and convenience. I value my hearing.

One about storing bleach and ammonia in a flammables cabinet, and one about storing them together. I agree that they probably shouldn't be stored in a flammables cabinet, but I firmly believe they should be stored separately, and I explained why. My posting was in response to your comments about them not reacting. He had said BLEACH and ammonia which DO REACT. You said "Calcium Hypochlorite" does not react with ammonia, which is correct (though my understanding is that it does react with water, if I recall correctly). I was trying to clarify things, because (on this side of the pond) one of the most common forms of bleach (Clorox) is NOT "Calcium Hypochlorite", but "SODIUM hypochlorite" which DOES INDEED REACT with ammonia. I was making sure that no one misunderstood your posting and tried mixing bleach & ammonia.

I actually meant to say something to the effect of it being "not something to mess with, unless you really know what you're doing." Lethality is definitely a good reason why one should not take it for granted.

Probably just vastly increasing the speed of corrosion, not that I really know. As for hazardous materials, something that is worth getting if you can get it free of cheaply is the US DoT hazardous materials first responder class. IIRC, it is 12 or so classroom hours and you can probably get it via your local fire department. It gives you much better information, and most of the cost will be buying the exceedingly useful reference books. http://hazmat.dot.gov/ I'm typing this from memory, so figure there will be some errors and omissions. HAZMATs come in a bunch of different varieties, all of which can kill you. A given material can have several different hazards. Plutonium, for instance, is radioactive, toxic, and a class D flammable all at the same time. The ones you are surely well aware of are flammables ( or inflammables) This further breaks down into the ABCD classifications that we know from fire extinguisher training. Related to flammables are explosives. They go boom and can level the building you are standing in. This is usually considered a bad thing. Next are poisons, which do bad things to your health once you get them into your body. The can get into your body to do the dirty deed by being inhaled, swallowed, skin or mucous membrane contact. Carcinogens are a subclass of poisons that cause cancer rather than directly killing you. Biohazards are active bacteria or viruses that will grow in your body and make you ill and maybe dead. Caustics and corrosives. These will dissolve your skin and the body parts underneath that they come into contact with. If a caustic (base) comes into contact with a corrosive (acid) they will usually react vigorously. By vigorously, I mean anything from boiling over the container to exploding and leveling the building, which is still a bad thing. Oxidizers. These will take ordinary flammable materials and make them far more vigorous. Want to see a demonstration? Take an ordinary charcoal briquette. Soak it in liquid oxygen for a while, then apply a match. Do this from a safe distance, fifty feet or so, as picking out bits of charcoal from your skin is painful, assuming you survive. The bomb that blew up the federal building in oklahoma city was a mixture of diesel fuel and a commonly available plant fertilizer which is an oxidizer. Reactives. Not too many of these, but they are especially dangerous. Add water to make them more dangerous. Metallic sodium is one of them. Radioactives. You do want to have children with the correct number of limbs don't you? Higher doses cause cancer, even higher doses will kill you slowly, over several days, in great pain. Have fun, but play safe. --Dale ------------------------------ End of Stagecraft Digest #522 *****************************
