Yes, I guess that's the million dollar (well £12.50) question.
I'd get a board, take it into the yard and see how it burns.
Now, I have many witnesses Brian and written proof that I didn't respond to the question by saying one should take it to the yard and torched.
But if you insist that torching it has to be then make sure you carry out a suitable and sufficient fire risk assessment of your experiment.
If you are within 20 miles of an oil refinery you should take advice from the H&SE, Fire & Rescue Service, Environmental Health Dept of your Council, The Presbyterian Woman - Ballyjamesduff Branch and, for good measure, The Royal Institute of Wheel Tappers and Shunters, and a fine body of shunters they are.
Have I covered everything sufficiently to ensure I don't end up sharing a cell with Wee Brian for 9 months?
