10mins is a massive amount of time for a fire.
It would have engulfed the shed in less than a minute, the other 9 mins would have seen it almost liquify.
We do a talk every year for new employees on how fast fires take hold.
Theres a bit in it where we show them a group of people who were invited to a try a new ice cream. They werent, the fire alarm goes off instead.
It wasnt until someone put fake smoke almost 7mins in that one person gets up to leave. Its 20mins before the rest decide to follow as a group.
Fires take hold fast, so even with all that flammable stuff in there im not surprised it burned as hard as it did.
And yeah 10mins is a massive amount of time when this kind of scenario is involved.
