So what should we do? Censor all discussions of stage collapses because it's a topic that makes some people uncomfortable? Perhaps we should ban all discussion of rigging or power in case someone gets an idea into their heads and produces a dangerous installation? No, that would be ridiculous. As Kerry has said above, these threads may come to the attention of production managers and put to the front of their minds the safety issues involved in running an event, which can only be a good thing. What we're trying to promote generally is a culture of safety across the industry (and many other industries), and the only way to achieve that is by talking about safety. The safety of an event isn't just down to the riggers. Everyone has a role to play, however big or small, so anything we can do to raise their awareness of safety the better. You may have rigged a perfectly appropriate stage, but then if the lighting and sound teams turn up with a different set of kit that weighs more, what do you do? Lets say the line array is changed last minute for one that weighs 20% more, but this information never makes it beyond the sound lot, who think it won't matter. Meanwhile, the lighting team bring a few extra movers, and all the movers weigh a bit more than expected because they're a magnetic ballasted lot cross-hired from another company, and no-one on site is even aware that it's happened. At the same time, the video wall manufacturer's data sheet contains an error in the wind loading factors to be applied. Who's now to blame that the structure's overloaded and potentially unsafe? None of the mistakes were made by riggers, they were made by people who wouldn't normally consider rigging safety, and that's the issue. You may know exactly how dangerous temporary structures can be, but does everyone else? And pointing fingers on the internet solves that? Raising safety awareness cannot be achieved efficiently by an internet forum pointing fingers from an uneducated, under-informed standpoint. (Uneducated and under-informed in the specific incident, that is). You can't form a sensible discussion you know nothing about. It will not achieve anything. It's simply unfair on the people you're accusing of not fulfilling their job description. There is no need to stop discussion about rigging. There is simply a need to stop under-informed, ill-educated and ultimately needless finger pointing sessions in the wake of tragic accidents. Just leave it. Talk about something else. Let the professionals deal with it, come to their own well-educated, well-informed decisions, publish a report, and then you can discuss the report to death. I think trying to suggest that crew involved in the hanging of heavy loads are ignorant to structural suitability is also ridiculous, and to suggest that an internet discussion about it would change their ways, even moreso. Every PA company I've ever installed points for has been thorough in which boxes they are hanging, how much they weigh, right down to the weight of the fly frames and any additional flying hardware. I do appreciate the point you are trying to make, but I think you are under-estimating the standard of people involved in such events. Hanging any load, particularly above the heads of people (public, performers or crew) is not taken lightly by anybody. When these accidents do occur, the cause can be complex and composed of numerous individual causes which in isolation may not be enough to cause the incident in question. The cause may also be something that was not immediately thought of. I can think of an incident where the loading dock of a stage collapsed and injured several people, the armchair experts were screaming blue murder about the stage not being fit for purpose and the stage crew not taking their job seriously and all the normal stuff, the actual reason it occurred was because a truck driver engaged the wrong gear and reversed 50 tons of lorry into it and knocked it over. Nothing structurally wrong with it, it was never designed to have a 50 ton lorry driven into it.
