A house fire that broke out in Mount Rainier early Tuesday has been contained with no injuries, but will leave the residence a “total loss,” according to officials.

According to spokesman Mark Brady, the Prince George’s County Fire Department received a call about a fire at a wood-framed, two-story home in the 3300 block of Otis Street about 5:45 a.m.

Firefighters arrived to find what Brady described as a “well involved” house fire that had spread from the home of origin to the houses on either side of it.

Brady said that the occupants of all three houses have been accounted for. None were injured, but a man and a woman were taken to a hospital for evaluation.

Brady also said that one firefighter suffered a “medical illness that may or may not be related to the fire.”

Firefighters rescued one dog from the home where the fire started, but a second dog died in the blaze.

One of the neighboring homes suffered minimal damage, but the other was damaged enough to displace its residents. The house where the fire originated was essentially destroyed, Brady said.

A total of 11 adults and 3 children will be displaced from two of the homes.

The cause of the fire is under investigation.
