From an AP story headlined “Mars Wrigley fined after workers fall into vat of chocolate”:

Federal workplace safety authorities have fined a Pennsylvania confectionary factory more than $14,500 following an accident in which two workers fell into a vat of chocolate.

The Occupational Safety and Health Administration cited Mars Wrigley in the accident at the Elizabethtown M&M/Mars factory, saying the workers were not authorized to work in the tanks and weren’t trained on the proper safety procedures for the equipment.
