Royd Anderson, a local documentarian who focuses on Louisiana history, will screen "The Continental Grain Elevator Explosion" at 3 p.m. on Friday, Dec. 22, at the Edith S. Lawson Westwego Library, 635 Fourth St., Westwego. The screening occurs on the 40th anniversary of the grain-elevator explosion.

The 30-minute documentary tells the story of the 1977 Westwego blast that killed 36 people  and remains the deadliest grain-dust explosion of the modern era.

The cause is still unknown, though federal and state investigators at the time thought that it was caused by a buildup of grain that had not been moved because of a national dockworkers' strike that year.

Gasses form when grain is kept in an enclosure, and they can explode under certain circumstances. A spark from machinery or static electricity could have led to the explosion.

The blast destroyed 48 of the 73 giant silos used to store soybeans, wheat and oats at the plant. Most of the men who died were trapped in a two-story, cinder block office building that was crushed when a 25-story grain elevator blew up.

Because of the explosion, safety regulations have been implemented for grain elevators nationally and abroad. Now, heat sensors are installed so that workers will be warned if a machine overheats. Pressure sensors also help reduce the thermal expansion of grain dust, and offices and control rooms have been moved to remote locations on plant sites.

Anderson is an alumnus of Loyola University New Orleans, the University of Louisiana at Lafayette and Delgado Community College. In addition to being a filmmaker, Anderson is also a former high school teacher.
