The Tucson Fire Department had to take a defensive approach to a Midtown fire this morning because of explosions coming from the burning building.
According to a TFD news release, two firefighters approached cautiously because of reports of explosions coming from inside the building in the 1800 block of North 9th Avenue, near Grant and Stone.
As they approached, a large explosion blew off the top half of a roll-up door and the decision was made to fight the fire from outside.
TFD Public Information Officer Barrett Baker said the fire was contained to one storage unit, which was used for personal storage, and called under control 28 minutes after the first firefighters arrived.
The storage unit was unoccupied and no one was injured.
An investigation is underway to determine the cause of the fire and the source of the explosions. No estimate of damages is available yet.
