Milwaukee firefighters say a garage explosion Tuesday morning happened when the flames reached a propane tank.
Video shows flames and thick black smoke coming from the garage just before the blast.
A We Energies repair crew was called to the scene because some overhead electric lines were damaged.
It took firefighters about 30 minutes to bring things under control, but the garage was a total loss.
A man who had been working inside the garage managed to get out safely and no injuries were reported.
Officials say two neighboring garages were also damaged by flames and heat.
