LAFAYETTE — The investigation into what caused Tuesday’s chemical fire in New Iberia awaits cleanup of the scene, officials said Thursday.

The fire began shortly before 4 p.m. Tuesday at Multi-Chem Group on West Admiral Doyle Drive, a site of a Texas company that supplies chemicals to the oil industry.

The fire burned 24 hours and was extinguished Wednesday afternoon.

A 1-mile evacuation order for the area was lifted Thursday morning enabling area businesses to reopen and residents to return home.

The company’s claims center at 6301 Coteau Road in New Iberia will remain open daily from 7 a.m. to 7 p.m. until further notice, said Katie Dupuis, Multi-Chem’s technical marketing manager.

A claims assistance hotline is also accessible at (866) 298-2558.

On Thursday, air quality monitoring by the Louisiana Department of Environmental Quality and a company hired by Multi-Chem continued to show no signs of contaminants, said Dupuis and Rodney Mallett, DEQ spokesman.

Mallett said DEQ personnel remain at the site to assist with the cleanup and for continual air monitoring. Water samples will also be taken from nearby Spanish Lake to monitor any possible environmental impact, Mallett added.
