The Calcasieu Parish Police Jury Office of Homeland Security and Emergency Preparedness has issued a precautionary shelter in place due to a warehouse fire at BioLab in Westlake.

The area affected is from the BioLab facility to a quarter-mile south due to wind direction.

Here are shelter in place instructions from the parish:

STEP 1 – GO INSIDE When inside stay inside until informed that it is safe to leave. This is more likely to be only a few hours, rather than a day or more. If your children are in school, their protection will be provided by school officials.

STEP 2 – SHUT DOORS AND WINDOWS Keep the contaminated air on the outside.

STEP 3 – TURN OFF HEATING, COOLING, OR VENTILATION SYSTEMS such as central units, window and attic fans. All of these systems bring in air from the outside
