There’s a lot of advice from firefighters on YT suggesting what to do before you abandon when wildfires are coming. Very interesting take, such as turn all the lights on.

What's the reasoning behind turning on all the lights?

Mainly so firefighters can easily see when they search for people still inside.

The hoses on outside etc was for flying embers.

Most people can't comphrehend the heat that is being generated and the volume of it.

Anyone that's been a KISS concert or a Wellington Phoenix or All Blacks game might have an idea, simply from the flame throwers that are used at those events - you can feel the radiated heat from across a stadium...imagine that across a several-acre area and I simply can't see how domestic water supplies (hoses, taps, sprinklers etc) could have any effect, other than if the ground and surrounds were saturated to the point of preventing the grass and garden areas from immediately igniting as the fire passed over/around.

i mean I could see that if you had several dozen meters of grass which was absolutely soaking in water, anything less will evaporate, or the fire will just jump, or proximity will just ignite.

I saw a video about the AU wildfires where they made a 80m firebreak, and it jumped it like it was nothing.

Ge0rge: Significantly faster and easier to do a search if the lights are on vs off.

Interesting. I'd have thought they'd be cutting the power to neighbourhoods that were in danger of getting hit by the fires in order to not have live wires all over the place if the fires did arrive.

Yes, absolutely. Or fires have swept through sub stations/ lines and cut the juice anyway. However, it's preferable if people do leave lights on, makes the job of search so much quicker. Pointing a torch in every corner / cupboard / under beds etc vs just looking quickly and moving on. Time saved can result in lives saved.

If it's not the oils and vapour from the gum leaves it's the bark peeling off the branches carried in the wind. They talk about fires jumping 30km.
