Firefighters knocked down a blaze in a home in Brighton on Friday. 

Four firefighters were injured and were taken to a hospital, according to the Boston Fire Department. None of the injuries are life-threatening. 

At around 7 p.m., firefighters responded to 72 Perthshire Rd., according to the Boston Fire Department.

The fire was in a 2.5 story home and caused around $500,000 in damage.

No civilians were injured, according to the fire department. Seven adults were displaced.

The Red Cross has been called to assist five of the adults, according to the fire department. 

The fire department says careless disposal of smoking material caused the fire and started in the 2nd floor rear porch. 

At one point during the blaze, crews feared a firefighter was trapped inside the burning home.
