Crews battled heavy smoke and flames in the early morning hours of New Year's Day, as a blaze was upgraded to 4-alarms.
Firefighters first responded to reports of a blaze in the warehouse of the Arrow Safety Device Co. on the 200 block of Holeman Street in Mount Holly, Burlington County, just after 3 a.m., officials said.
It took crews nearly four hours to get the fire under control.
No injuries have been reported.
Officials have yet to confirm whether the warehouse is in use, but the website for Arrow Safety Device indicated the firm no longer uses the Mount Holly facility.
