A dumpster behind MV Screenprinting on State Road in Tisbury caught flames Thursday at approximately 4:40 pm and was promptly extinguished by Tisbury firefighters.
According to Tisbury fire chief John Schilling, the dumpster was filled with highly combustible construction debris, including used aerosol cans.
According to Schilling, a black lid covering the dumpster could have created enough solar gain to make the flammable materials inside the dumpster spontaneously combust.
“Some solvents such as polyurethanes or aerosols are particularly prone to combustion, especially when temperatures reach over 105 degrees, which it easily could have reached inside that dumpster on a really hot day like today,” Schilling said.
