The facility is 100 kilometers (62 miles) south-west of Belgrade and is one of the largest defense enterprises in the country.
The Serbian Defense Ministry said later on Monday that only one employee was injured during the incident. A 40-years-old woman sustained injuries when a percussion device detonated while she was varnishing over it, the statement read. She was taken to a hospital in the city of Valjevo.
The ministry noted that the other employee was in the room at the time of the accident, but she was not injured. She was admitted to the same hospital for examination as she was in shock and then released home.
The enterprise has formed a special commission to investigate the cause of the incident, the ministry said.
