Justin Possinger, a carrier technician, was recently delivering mail in East Stroudsburg, PA, when he spotted an older couple waving him down from their residence.
As Possinger approached the home, he saw smoke billowing from the attic, so he immediately called 911 and guided the customers to safety away from the structure.
The couple, who had smelled smoke, had been unaware of the scope of the threat.
Firefighters soon arrived to battle the blaze.
“The fire chief stated that if they had stayed inside much longer, the whole house would have been full of flames,” said East Stroudsburg Postmaster Mike Taveras.
