Huh!
I think they said that the explosions came from the "LP gas" area and the reporter at the scene suggested that there my be a connection between the explosions and the layoffs, which apparently happened before the explosions and fire.
Seems unlikely, since seasonal factory work and layoffs are a normal part of life in that part of the country, and the propane area would be super-safe and unlikely to catch fire on its own. Glad no one was hurt.
Hmmmm...
