I bought a replacement wheel barrow once in poly. My wife decided to clean out the wood burner one afternoon. The fire had been out for 2 days. She pushed the wheel barrow full of ash outside under the deck. Luckily my neighbor was a smoker. At mid-night, he called me and says" Hey you have a flue fire". I run out on the deck and look up. No fire but a lot of smoke. The wheel barrow was fully engulfed under the deck and fire was licking up a post. There is still a melted plastic stain on the concrete. My new barrow is steel.
