Explosives co. faced scrutiny before La evacuation

Explo Systems Inc. was cited for safety violations by the federal government in 2007 for its use of old Army explosives in mining operations in West Virginia, where a blast with "outdated deteriorated military ordnance" injured one worker and exposed others to toxins. And the company had fallen hundreds of thousands of dollar behind on its rent at a Louisiana National Guard base even as it processed an Army contract to demilitarize hundreds of thousands of propelling charges used for artillery.
