Is it safe to put a Charcoal Grill on a Wood Deck?

I have a wood deck under one of my “burn” areas, as active grill collections are known in the biz. I keep the deck safe by placing fireproof grill pads under each grill. Manufactured by DiversiTech, grill pads come in a variety of sizes, shapes, and colors and are available at grill shops, hardware and houseware stores, and via the Web at: www.grillpads.com.
