Re: Another case of questionable rigging?
One more point - temporary demountable entertainment structures (roofs, stages, grandstands, goal-post towers, etc) have been receiving more and more scrutiny after well-publicized failures over the last few years.
I've mentioned in another thread (and maybe on a different forum) that it's a pretty good idea to go the State of Indiana's website and find the reports about the 2011 State Fair roof failure. The forensic engineering was done by Thornton Tomasetti. You can read the Executive Summary first, but the entire report deserves a reading. When you're done I predict you'll have a very different view of physics (unforgiving), nature (likewise), and situational/human failings. Cap off the readingfest with Witt Associates analysis of the pre-emergency planning, chain of command and control, post-emergency planning, and the implementation of those plans.
People who put up stuff like we see in the picture get away with it because they haven't had their own personal incident where gravity (sometimes accompanied by nature) brings stuff crashing to the ground. Their clients don't know any better and probably assume the vendor is providing an *engineered roof (or staging) system* and will assemble the system as called out in the engineering manual; that all components of the system are of known good and suitable condition and that the system technician has sufficient training and experience to supervise workers and inspect the results of work done. That or the customer is told "don't worry, we've got that covered" and the client checks off "roof" from the to-do list. :roll:
One more thing - how many of us have an emergency plan for on-site? Where do you meet? Who checks everyone in? Does someone off-site have a list of your crew and contact info? Where is the fire extinguisher? First aid kit? Who on your crew have had Red Cross first aid class? CPR? Which crew members know about those folks?
And the last part brings me to a final plug... your Red Cross. Please send your crew (even if that's only you) to Basic First Aid and CPR class. I can't think of a better investment to make in your crew.
