No injuries - July 23 storm came near end of sound check
« on: August 19, 2011, 01:28:36 pm »

Seeing the pattern of outdoor tragedies recently, I thought I'd send out these before and after pics of a storm that rudely ended our festival week in Bathurst, New Brunswick, Canada on July 23rd.

Details:
  • 4x EAW 650 per side on truss held up with Genie lifts
  • 3000 cap show tent
  • 3 CDN rock bands had been billed for that SATURDAY night concert: Honeymoon Suite; Harlequin; The Headpins.  Tent would have been packed 2 1/2 hours after time storm hit us.  Very lucky with timing, to say the least!
  • As I was finishing my last tweak of monitors for 3rd band, got a tap on my shoulder that visible lightning meant 60 s notice to power distro shutdown.  Two minutes later, the tent poles (>250 lbs) were lifting 3 ~ 4 feet off the pavement, and our end of the tent came down, taking front and rear truss with it.

As in other (sadly much worse) stage collapses this summer, I keep asking why weren't weather warnings brought to our attention earlier?

Shane,

I feel for you. We had a tornado hit a fair grounds we were at last summer. The only thing that was holding what was left of the tent was our gear. Between a couple of tents we lost 85K worth of gear.

Fortunately ours came through at 3AM and nobody was injured.

We are still fighting American Family Insurance over that one. Hope you were not insured by them.

That same fair is talking about having us do three grandstand concerts next year with a large stage and roof...

I've been forwarding them all the photo's of the last three large stage derailments...

What a kick in the pants to our industry...and I really feel for the people that were killed or injured. Equipment can always be replaced.

Weather can do odd things. years ago was at a Greek festival in Houston, freak storm came up out of nowhere. No rain, a little bit of wind, and then a small 10x10 booth/canopy rig right in front of me just exploded. An elderly woman walking by was severely injured by a 2x12 that was thrown about 15'. No other damage or injuries, very bizarre.

"Bathurst Blowdown" & rigging gear

   Hello,

   Sorry to hear of this storm taking out your gear too...

   A steel safety is not the only thing that they missed... the 650s were hung on the bottom of the truss, it should have been hung off of the top.

I'm not a rigger and I don't know, but will certainly forward your Q to the sound company (my client for the x-rented sidefill system).

The sound company's own crew had already hung the PA tops, the day before my arrival at the festival.

Looking also at Charlies' post (re: hanging from the bottom - rather than from the top - of the truss), I'm very interested in passing this info on to my client and learning the answers.

The stage (put up by a different contractor before the sound company arrived), also lacked a perimeter guardrail.  I overheard some talk of provincial labour code requirements, but to no avail.  You'd be right if you guessed that someone fell off; earlier on in the festival's week a local crew person fell behind the drum kit, head first onto the distro.  The festivals' luck was with them again: he was observed and came back to work the next day.  Quite a week for him!

Those are not genie lifts.  They are Global Truss ST180s.  You are significantly over their weight limit with just the KF650s, even worse when you add the weight of the lights!

   Hmm... I originally had just a quick glance at the photos, now I'm starting to see some other silly things they missed or that is inappropriate...  like the top boxes should have been hung upside down ..... and...the side fills should have been strapped....etc...
 

   Maybe, you should hire a different Company in the future, or at least until they get a clue.

I was a sub-vendor to the sound company, not the buyer.

The 4738 (sidefill top: Lo Mid Hi) sits very stably on the 4718 (supplemental Lo) oweing to the deep interlocking corners.  Of course, on any outdoor show sans tent walls, or on any unstable surface I always strap them and indeed I offered to here.  Not expecting the tent to disappear :'(, the client was content with the inherent stability the stack demonstrated.  Moreover, note how, at the 25s mark in the video, it toppled as one.

As to flipping the FoH tops, I was unaware of their orientation.  Aside from a quick walk during CCR's set, I didn't spend any time out front and so can't comment on coverage or combing issues.

Question: wouldn't the location of the HI horn in the middle of the 650e cab, diminish, at least in the HI band, the benefit normally derived from flipping the top?  True, the MF horns would have been better coupled, but that's MF, not HF, and with the bottom row's down tilt he employed there, I'm uncertain as to the extent of any improvement to be had.

They opted for this deployment as an alternative to a delay stack; it was a long tent and the usual festival budget and space compromises must have been at play. [/speculation]

All safety comments should be taken into consideration, but I think this thing was going over in that storm no matter what. Not excusing the mistakes, just saying. I am thankful everyone was ok.
