A burning chemical plant may be just the tip of Hurricane Laura’s damage in this area of oil fields and industry

Hurricane Laura plowed through the heart of Louisiana’s oil and chemical industries as a powerful Category 4 storm, leaving a chlorine plant on fire and the potential for more hazardous damage in its wake. The burning BioLab facility sent dark smoke and chlorine gas into the air over the small community of Westlake, near Lake Charles, and shut down Interstate 10, officials said. The governor warned residents, already reeling from the hurricane’s damage, to stay in their homes, close their windows and doors, and turn off any air conditioning that might still be operating. While the full health impacts of the fire weren’t immediately known, a storm-driven chlorine gas release in a vulnerable community is the type of worst-case scenario that scientists and engineers like myself have warned ...

Video footage appears to show a fire burning nearby before the blast. Ammonium nitrate has the chemical formula NH₄NO₃. Produced as small porous pellets, or “prills”, it’s one of the world’s most widely used fertilisers. It is also the main component in many types of mining explosives, where it’s mixed with fuel oil and detonated by an explosive charge. For an industrial ammonium nitrate disaster to occur, a lot needs to go wrong. Tragically, this seems to have been the case in Beirut. What could h...
