Theatre Fire?

OK I maybe made an assumption based on the title of your original post. If the fire alarm has gone off in a public building then the mains power is interrupted and the emergency lighting comes on. I am assuming that a modern alarm system is installed. If you have a lighting malfunction and "the theatre is full of smoke" then there is almost certainly a likelihood that the smoke detectors have gone off which will then set off the fire alarm. At this point the designated fire officer should begin an orderly evacuation no other consideration should come into play. If the "theatre is full of smoke" because of a runaway smoke effect and the theatre is plunged into darkness because of a lighting board malfunction or operator collapse the the SM's responsibility is to ascertain the exact situation ASAP. This actually implies that the first steps on a process that leads to evacuation must be taken. We cannot ever play roulette with human lives. If the SM is aware that it is simply a BO and a smoke machine effect then he/she should immediately call the next cue. Problem solved. So why did your post start "Theatre Fire!" if that was the case. Is that all there is? Well if that's all there is my friend, then let's keep dancing. www.tonymoore.id.au
