Armchair Quarterback Video - Week 5

For this week I give a big thank you to /u/Shekkishi for sending this video to me. You can view it Here. As /u/Shekkishi said to me and I have to agree, with winter approaching, and for some places its already here, this would be a good safety reminder.

Please remember to stick to the rules, and keep your posts civil.

Do you have a video you would like to submit for the disccusion? Send it to me /u/karazykid, or message the mods!

u/RobertTheSpruce UK Fire - CM Dec 02 '13

That's one of the classics isn't it? Making a pointless hole, with no one footing the ladder, standing on an icy roof, and no fall restraint systems.

u/Doc_Wyatt TX dumpster fire on wheels Dec 03 '13

No one footing the ladder is just a stupid mistake - but you're right, why are they taking the saw up to the garage roof in the first place? The fire isn't in the garage, and the part of the house that the fire is actually located in looks to be pretty well vented already.

I've been instructed that vertical ventilation is important in a lot of situations, but this is just stupid. Can anyone come up with even a slightly plausible reason for this?

Vertical ventilation is only useful though if it is directly over the main body of fire (or as close as possible) in order to allow the smoke/heat to rise from there. By making a vertical vent hole remote from where the fire is you create a flow path that is likely to draw the fire towards that vent hole and thus help it spread.

But back to the obvious point: The fire is already through the roof, another hole is pointless.
