Beware combustible compost

Palaisglide - Frank, good post. Every fire has a cause, the loss adjusters had much more interesting jobs than us underwriters. There was an assumption that the fire started inside the greenhouse. Logic would suggest it didn't.

Beware combustible compost

Posted: 31/08/2012 at 09:23

As an retired fire underwriter for one of the large Insurance companies, I am fascinated by incidents like this. I also use peat compost and have a plastic pollytunnel. To have a fire you basically need 3 things – fuel, oxygen and either a heat source at or above the fuels flash point or in respect of spontaneous combustion - a temperature at or above it's auto ignition point. The flash point of peat is 225 degrees C or 437 F and the auto ignition point is 260 degrees C or 500 F. The hottest temperature I have recorded in my pollytunnel this year is 45 degrees C or 113 F. Unfortunately, like UFO mysteries, you will probably never know what really happened.
