The white lie that contributed to a big explosion

Many dangerous chemicals were used for said flares produced in the factory to be created such as Magnesium and Potassium Nitrate- chemicals that were purposefully misclassified as less harmful than they actually were, so flares could be mass produced.

Instead of these chemicals being handled like the explosives they were, they were treated as only flammable. After the events of the explosion, the U.S government was formally found guilty of purposefully not informing the factory of the real dangers of the products.
