The seats are made of a petroleum compound that causes high heat, according to Nexstar’s KDVR, but what impact that had on the spread of the fire is also under investigation.

Investigators are also looking to see if there is any significant damage that could impact the structural safety of the stadium.

Approximately 1,000 square feet was burned in the fire and the sprinkler system was working but no one was hurt, Denver Fire Captain Greg Pixley said.
