Title: Stage Fire in India from electrical short
Post by: Mike Sokol on February 17, 2017, 10:19:16 AM
It doesn't appear that anyone got injured or killed, but the stage and all production gear must have been a complete loss. Report says the fire started from an electrical short circuit http://www.india.com/news/india/make-in-india-fire-stage-caught-fire-due-to-electrical-short-circuit-says-report-977207/ (http://www.india.com/news/india/make-in-india-fire-stage-caught-fire-due-to-electrical-short-circuit-says-report-977207/)

Didn't another incident just like this happen not too long ago?

an electrical spark had come in contact with the inflammable materials under the stage and that aggravated the situation even further. “The LPG cylinder in the vicinity burst after coming in contact with the fire and it leaked the entire stage quickly due to high wind speed,”
The "organizers" need to see the inside of a jail cell.

I saw a fire like this start along the DS edge of a stage, the band had used a 1/4'' instrument cable to jump in between 2 wedges and it heated up to the point of flames. It was quickly seen and extinguished but it's easy to see how some of these things happen. Imagine if that cable had been up stage next to a bunch of drape, fabric or scenery.
It was just a 3 piece band using a little sound system, one wouldn't think you could wire it up and create a fire hazard like this but it just goes to show the endless possibilities of accidents that can happen. Always be thinking of "what if" scenarios and plan and place thins accordingly.

...Report says the fire started from an electrical short circuit...

Keep in mind that to most laymen, any electrical problem is a "short circuit." (The term is probably more often used to refer to an open circuit than an actual short!)

"During examination of the of the accident, the officials found that an electrical spark had come in contact with the inflammable materials under the stage..."

An electrical arc doesn't necessarily imply a "short circuit" (in the technical sense). Yes, it could have been a short, but the article doesn't really make this clear.

That's another reason 1/4" connectors are a terrible idea for passive speaker connections.

There's also the matter of 1/4" connectors having a rather small contact patch between the plug and the jack.

From the date on the linked story, this is probably the one you are thinking of.

So the materials that aren't flammable caught on fire?

I remember the days when flammable was the opposite to inflammable....apparently not anymore.

EDIT :

They mean the same thing ( although flammable doesn't really exist????) and the opposite to inflammable is nonflammable..according to the sources I have researched.....

From good old Wikipedia... (https://en.wikipedia.org/wiki/Flammability)
Historically, flammable, inflammable and combustible meant capable of burning.[1] The word "inflammable" came through French from the Latin inflammāre = "to set fire to," where the Latin preposition "in-"[2] means "in" as in "indoctrinate", rather than "not" as in "invisible" and "ineligible".

The word "inflammable" may be erroneously thought to mean "non-flammable".[3] The erroneous usage of the word "inflammable" is a significant safety hazard. Therefore, since the 1950s, efforts to put forward the use of "flammable" in place of "inflammable" were accepted by linguists, and it is now the accepted standard in American English and British English.[4][5] Antonyms of "flammable/inflammable" include: non-flammable, non-inflammable, incombustible, non-combustible, ininflammable,[citation needed] not flammable, and fireproof.

Welcome to the English language.

Where the contents aren't very contenting.

Though and rough should rhyme with cough through some strange reason, perhaps, why pony and bologna do, they don't.

And no one knows whether it is either read, either read.

I want to know if the audit passed prior to the event starting with or without the combustible items beneath stage.

“A fire safety audit was also conducted prior to programme and all Standard Operating Procedures (SOPs) were followed. A comprehensive inquiry into the incidence of fire will be conducted to ascertain reasons,” Fadnavis had said while ordering for the detailed probe.

I'm sure it passed with the combustible currency beneath the table.

(Yes, that is an unfair accusation of corruption with no basis in fact.)

Yes, that's the same stage. That's some pretty serious pyro...

This was a big government sanctioned event with all sorts of politicians and Bollywood celebrities in attendance. Everyone had to be evacuated in a hurry.

Yes - absolutely.  Everything is also negotiable and can be handled with a bribe.  Additionally time is a very loose concept. 

Of course I've never been to India but based on the 15 to 20 Indian groups we work with ina given year....

They were using a K1 system. I almost shed a tear for the owner.

In the words of George Carlin, "Flammable, inflammable & nonflammable... Why are there three? Don't you think that two ought to serve the purpose? I mean either the thing flams or it doesn't!"

So using the same English rules, many of those that reply here are "inhospitable" to those that ask silly questions.  Did I use the word correctly?

I did shed a tear for the owner. He's a good friend and one of the best rental companies around.
  I can assure you that that all safety codes were followed to the letter. They are my preferred vendor of choice for the bands  I mix for.
  This happened last year at a big government funded and organised initiative. The fore started when some government officials wanted to use fire crackers next to the stage and despite being refused permission by the vendors and fire brigade, they went ahead and did so. You can see what happened next.
  They lost a boatload of K1 cabinets, about 3 avid stage boxes, all of the trussing and a ton of cables.
  It led to a bunch of us engineers coming up with a safety pact which we try and follow as no one else does. We're fortunate enough to be touring with artists that support us!
