PORTLAND, Maine — Fire officials in Maine say there’s no word on what caused a trailer that held fireworks to explode following a July 4 show in Portland.
No one was injured in the 10 p.m. explosion Sunday, just after the end of the city’s fireworks display.
Officials say the trailer contained about 300 plastic tubes used to fire the shells.
Portland Deputy Fire Chief Mike Shutts said firefighters, police and event staff evacuated the area after the explosion.
Shutts said the fire was managed from a distance, meaning firefighters let the trailer burn itself out.
