The firefighter suffered a burn on his left hand after falling into the dumpster, which was heated by a fire at the Heim Bearing Co. on Tuesday, June 30, according to fire officials.
Officials said the pattern of fire development pointed to an ignition area inside the dumpster, which contained wood pallets, cardboard and plastic wrap.
The dumpster was touching the loading dock and heat transfer caused the padding surrounding the overhead doors to ignite, fire officials said.
Smoke traveled into the main building until an employee closed the manually operated fire door. An employee activated the fire alarm and the building was safely evacuated, fire officials said.
Although the exact cause is undetermined, numerous discarded cigarettes were found around the dumpster, fire officials said.
