Two small chlorine leaks injured a contract worker at the Olin Corporation facilities within the Dow Chemical plant in Plaquemine, authorities reported Thursday afternoon.

Laurie Doiron, director of Iberville Parish's Office of Emergency Preparedness, said the leaks posed no threat to the public. 

"Everything was below reportable quantities," she said Thursday afternoon. 

Doiron said both leaks occurred after several electrical rectifiers at the Olin plant tripped — one at 10:24 a.m. and three more at 1:56 p.m. Thursday. 

One worker employed by one of Olin's contractor was transported to Dow's onsite medical facility for treatment, Doiron said. She had no further information about the worker's condition.

Thursday's incident is the second reported chemical release at the Olin plant within an eight-month period.

A power outage in December temporarily shut down production units, sparking a chlorine release.

Although plant officials said at the time that the chlorine leak was contained on site, Doiron's office heard from people living in the area who reported difficulty breathing and described having burning sensations in their eyes.
