Safeopedia explains Mulch
The Board of Fire Protection Regulations (BFPR) has developed regulations with regard to the production of mulch. This is due to large fires in the commonwealth. These regulations include guidelines for the safe storage and manufacture of mulch, for companies that make their own mulch. This is because large piles of mulch can easily spontaneously combust due to the extreme heat generated in storage, and the dryness of the material. Mulch is usually composed of straw, leaves, small pieces of wood, sawdust, compost, or paper.
