Hm. If we actually had flys, lifts, a need for a large ladder, an actual shop, wings, mobile sets, speaker stacks... then I would definitely be safe with them.
But we don't I'll see what happens this weekend on build shift... expect a report |

Yea, I agree with that.
Heres a story from today that I just found out: Ok, backround story: My school, as im sure everyone knows, isn't to well equiped. We're getting some cool new stuff, and i'll post specs on everything when thats all finalized. Currently, we put are movible stage in the gym, and use are 12, well, 11 cause were missing one somewhere 500 watt fernels. These are short compleatly underpowered for the space, and have trouble lighting something thats like 20 feet away. Because of this the center of the stage is always washed out and dark, so we put the (removable) poles where we attach the lights to right next to the stage. We then run extention cords all over the gym, plugging the lights into the normal sockets (for the shows we would patch into our American DJ board). However, the little kids (pre-k through 6th) need to be able to get through the "back stage" area, so consequently I tape down the coards with half a roll of duct tape, to make sure that a little kid dosen't trip on the coards and sue the school (or me). Thats my first sugestion, tape down all of the coards down whereever people are walking. Today i was told, however, that one of the little kids was playing with our lighting poll, and swinging it back and forth. Now, this is a 10 foot iron poll, with 6 lights on the top of it. Its hard to start to move, but once its moving it is hard to stop, and theres a little kid on the bottom of it, playing with it and moving all of the lights, about to break everything, and have the 100 lbs of metal and glass fall on top of him!!!! Now, I intentionally keep the poles out of the way of traffic, so this kid needed to go up to the poll and physically grab it and pull on it!!!! I'm trying to figure out a way to prevent this type of thing. As soon as we get our perminent set-up (sould go up during the Febuary Break), this won't be needed, but if I ever want to set-up lights on the polls, how do I stop stupid kids from playing with them???

Two options:
Sandbag the pole bases, making them so bottom-heavy that no kid's going to move them easily. Cordon off that area somehow, and inform whoever's looking after the children that any kids within the line (or whatever) are on their own once inside. Hopefully that will at least wake up the supervisors. |

I don't know if we have any sand bags, but i'll try to find them. The problem is there is usually one teacher watching 30 or 40 little kids during lunch, so its kind of hectic....
I'll try to rope off the area at least, we've got some rope and stuff somewhere lieing around....

Booms in the industry be it 10' or 30 foot regularially get tied off to the grid to ensure they cannot fall over. As simple as a pipe cap above the pipe that's drilled out for mounting an eye bolt to it. Than your choice, suitable wire rope or regular rope that is able to hold the weight is tied off to the grid or rafters above not enough to pick up the boom, but enough to ensure it won't fall over. Perhaps that will be your solution especially considering most boom bases are 40#. As for sand bags, I'm not a huge fan of them unless they are tied directly to the boom. Too easy to slide off, much less they will do so once it starts a rocking. I use them to help add weight but always tie them to the boom at that point. Another option would be two fold. First, drill the boom base and attach a 3/4" plywood 4' square base to it. Than add on the sand bags if not build a frame around it to retain them. In this way, the base footprint of the boom is much larger than the normal 30" and that in resisting tipping makes less weight necessary. It also being one large boom base lets the sand bags be applied in a less towards the center type way. Putting them towards the edges would help more than the center. If no plywood, still tie them to the center boom, but on a longer cord so they remain towards the edge. Another advantage of the plywood, especially if it's edge is rounded over is that it will prevent tripping over the boom base that could injure someone in the dark much less move your lights.
On sand bags, usually you can purchase just the bag and fill it as time permits. Lots of industrial supply places would have them amongst them Grainger and McMaster Carr if not a garden shop. You can also buy more sturdy ones from theater supply houses. What ever the case, avoid duct tape and use gaffers tape. It is much less likely to leave a residue on what it's attached to and not a huge amount more expensive. Normal minimum practice otherwise would be to buy some 27" vinyl ribbed hallway runner and cut it into say 9" wide strips. Tape the runner over the wires so it's less of something to trip over. Gaffers tape normally will go for $15.00 per roll. If you lock it up between uses, you should get at least half a season out of it given it's not used for everything. |

when working in a theatre with a fly tower, or grid i feel when rigging it is quite important before you take up your bar or grid it is a good idea to shout "lx 4 (grid 1 etc.) moving, heads up on stage!"

And we always call out any boom movements. Its definately standard practice here.
