HOUSTON, June 14 (Xinhua) -- One person was killed and five others were injured in an explosion that rattled a fertilizer plant in the U.S. state of Louisiana Friday evening, local media reported.
The explosion, caused by a nitrogen vessel rupture, happened at around 6:15 p.m. at CF Industries in Donaldsonville, a southern city located along the west bank of the Mississippi River, local media NOLA.COM reported.
The blast killed one person and injured five others, including three who are in critical condition, Louisiana State Police spokesman Trooper Jared Sandifer told the media. NOLA initially counted the number of the injured as seven.
Sandifer said that workers over-pressured the nitrogen vessel, causing it to explode. There was no fire at the scene and no chemical leakage was detected, local officials said.
The incident happened only one day after a chemical plant producing ethylene was rocked by a blast in which two people were killed and 77 others were injured in another city miles away from Donaldsonville in Louisiana.
