100 violations, $3.1M fine issued in Tennessee plant blast that killed 16

State findings: 100 citations, record penalty, 'indifference to worker safety'

what the source states

"The Tennessee Occupational Safety and Health Administration has issued 100 safety citations and more than $3.1 million in penalties following its investigation... The agency described the case as the largest investigation in its history and the highest total penalty it has ever assessed."

what we infer

A facility whose regulator documents systemic safety failures supplies the mundane explanation the sabotage reading must beat. (WPLN's historical review places the blast as the deadliest U.S. explosion of the century, "the most lethal... since a petrochemical plant owned by ARCO in Texas exploded in 1990" — note the compilation's "34 years / above-ground" phrasing was not found in any authoritative source.)

limitations

• Verified via search-index excerpts of the two local reports rather than end-to-end fetches; quotes limited accordingly.
• Documented negligence and deliberate causation are not mutually exclusive; only the cause finding settles it.
