How Forgotten Work Lights Caused a $43 Million Chemical Plant Explosion

Описание: How did forgotten work lights contribute to a $43 million chemical plant explosion?

On July 14, 2023, a series of explosions and fires struck Dow Chemical's Louisiana Operations facility in Plaquemine, Louisiana, releasing approximately 31,525 pounds of toxic ethylene oxide.

Investigators from the U.S. Chemical Safety Board (CSB) traced the catastrophe to an extraordinary chain of engineering and process safety failures.

In this documentary, Engineering Insight Hub investigates:

How portable work lights were left inside a reflux drum after maintenance
How metallic debris affected downstream equipment and punctured a rupture disc
Why the loss of nitrogen inerting created a dangerous condition
How flames travelled through pressure-relief piping
Why the reflux drum failed catastrophically
The critical lessons for commissioning, maintenance, process safety and asset integrity

*The consequences:* $43 million in estimated property damage, a major chemical release and a shelter-in-place order. Fortunately, no injuries were reported.
