The CPSC is aware of at least 37 deaths and 113 injuries between 1978 and 1995 that resulted from consumers jolting or tipping the vending machines to get free soda or money.
In cooperation with the U.S. Consumer Product Safety Commission (CPSC), in 1995 seven vending machine manufacturers have placed warning labels to alert consumers that shaking or tipping vending machines can result in death or injury.
The label says: "Warning! Never shake or tip. The vending machine can fall over and cause serious injury or death. The vending machine does not dispense free product." Other labels contain similar warnings with graphics illustrating that the vending machines can tip over.
