Seven men were injured Thursday in an explosion on a vessel anchored at a dock at a cement plant in southwestern Japan, according to the local police and fire department.
Of the seven, at least three were severely burned following the explosion on a 500-ton, 60-meter-long cargo ship loaded with soil, they said.
Firefighters received a call at around 9:40 a.m. reporting that an explosion had occurred on a vessel and some people were injured at the plant, which belongs to Mitsubishi UBE Cement Corp., in Fukuoka Prefecture.
The explosion occurred when a hatch on the vessel was opened but no fire broke out, the police said.
A 51-year-old man at an auto parts company, located about 100 meters away from the scene, heard a loud boom.
"I was surprised," he said. "We panicked in the office."
