MIAMI (CBSMiami) – A fire which ripped through a Miami warehouse packed with art work and art supplies on Wednesday is still burning.

Miami Fire Rescue said they’ll keep personnel at the “Art by God” building at 60 NE 27th Avenue until they can be sure the fire is completely out. One of their concerns is that impact the restaurant equipment company next door.

More than 80 firefighters battled the fire throughout the day. By early afternoon, the collapse of the roof created even more problems.

Two firefighters were treated for heat exhaustion and dehydration.

The cause of the fire is undetermined because investigators have not been able to get into the building.

Miami Avenue from 26th Street to 28th Street remains closed to traffic.
