Primary determinants are the structure of the forest, the amount of trees, tree density and the characteristics of the combustible fuel.

This means plants are selectively thinned and pruned to reduce the combustible fuel mass of the remaining plants.

He said that there was an urgent need to save other historic movies held in archives before the combustible material on which they were made was lost.

Fire tests for the study found that ethylene vinyl acetate - a material commonly used in the panels - appeared to be 'a rapidly combustible material releasing gaseous fuels ... once degraded thermally'.

I wonder whether the situation, which can on occasion look highly combustible, might not be defused.
