I sincerely hope the fires are brought under control with minimal damage to life and property, it must be horrendous living in that area, what a terrible situation.
Personally i'd be fkd if the electric went out, within 15/20 seconds of the light going off the smell drops out of the tent vents, the neighbours would smell within the hour without ventilation.
In the past I've used 1 way vents made with with plastic sheet, when there's air pressure it lifts but when the fan goes off they hang down sealing the vent
But I don't require them now so it would be stinking and the lousy feckers have already reported me some years ago, a chap I grew up with... Wanker.
