A Suffolk County family made it out of their home safely when a fire broke out Thursday afternoon.

The Riverhead Fire Department responded to the report of a blaze at a residential structure around 2 p.m. at the corner of Sweezy Avenue and Lincoln Street in Polish Town.

Once on scene, crews were met with heavy smoke and active fire conditions on the second floor of the house.

Approximately 50 firefighters, from a total of six local East End volunteer departments, responded to the scene and provided standby coverage at Riverhead’s headquarters, fire officials say.

First responders worked to extinguish the flames and prevent it from spreading to neighboring homes, before placing it under control at 2:54 p.m.

The two adults and an infant who were inside at the time were transported to area hospitals for evaluation, according to the Riverhead Fire Department.

A dog was also able to escape the residence unharmed, but a cat did not survive the fire.

The cause is currently under investigation by the Riverhead Town Fire Marshal’s Office.
