The sudden heat wave has brought something more menacing than sunburns and higher electric bills. The latest sign of summer just might be spontaneous combustion.
Arlington schools Superintendent Mac Bernd announced Monday that he would replace all the "engineered wood fiber" material on the district's playgrounds after one burst into flames last week. A review of footage from a surveillance camera determined that no one was around to start the fire – either accidentally or intentionally.
"It was like a perfect storm," said Deputy Fire Marshal Keith Ebel.
He said the fire Thursday at Anderson Elementary apparently started from heat generated by decomposition of the wood chips and high temperatures from the recent heat wave. Marshal Ebel said this might not have happened without the rainy first half of the summer followed by high heat.
