(Newser) – It's a story out of Pennsylvania that Today describes as "something straight out of Charlie and the Chocolate Factory." The local fire department received quite an unusual call on Thursday, when it was informed that two maintenance workers at the Mars Wrigley plant in Elizabethtown, known for making M&Ms and other sweet treats, had fallen into a vat of chocolate and couldn't get out. According to the Lancaster County 911 dispatch, the chocolate was said to have been about waist-deep, reports PennLive.com.

The dispatch notes that the employees fell into the vat shortly before 2pm local time. Fire crews tried to pull the workers out of the tank but couldn't, so instead, they had to "cut a hole in the side of the tank to get them out," dispatch communications supervisor Brad Wolfe tells CNN, adding that it wasn't yet clear how the workers fell into the vat. WHTM reports that the first employee was freed at around 3:10pm, and the second 15 minutes later.

Both were taken to area hospitals, likely as a precaution, as Wolfe tells CNN that no injuries had been reported. A Mars Wrigley spokesperson said the company was "extremely grateful for the quick work of the first responders," per WHTM. The Occupational Safety and Health Administration is investigating the incident. (Read more chocolate stories.)
