Two firefighters were injured after a fire broke out Thursday morning at a New Jersey building that houses a post office, officials say.
Flames broke out near the roof of the building on First Street in Carlstadt about 1:30 a.m., according to Fire Chief Rob Popejoy. The blaze quickly spread, causing part of the roof to collapse and sending heavy flames and smoke into the sky.
More than 100 firefighters were sent to the three-alarm blaze, which was brought under control by about 4:45 a.m., firefighters say.
The top floor, which houses an electrical supply store, sustained heavy fire damage, firefighters say. The post office on the first floor had water damage.
One firefighter was taken to the hospital and another was treated at the scene for minor injuries, officials said.
A representative from the U.S. Postal Service was at the scene to check on the packages and parcels. Popejoy said post offices are usually fortified against damage, so the mail is protected.
"I've got bills in there too," he said.

It's not clear what sparked the blaze, but Popejoy said work was being done to the roof on Wednesday.
