The decision to
throw on lights to help get people out was in my opinion the right thing to do. It isn't just the exits that need to be lit in these circumstances, but everything that might be in the way to them (dropped items, those caring for the wounded,
etc.). These are things that need to be considered when coming up with a plan. Assume that some of the regular means of
egress will no longer be accessible and make sure that there is direction to alternate exits and have a means of directing people to them as the audience needs to know before heading for the wrong exit.
