Abstract: At approximately 6:30 a.m. on June 19, 1993, Employee #1 was engaged in removing product carts from the #7 humidifier. As the second cart approached the entrance of the humidifier, he noticed that some products had been pushed out from the cart. He positioned himself between the cart and the humidifier so as to return the product to its normal position. Unknown to Employee #1, the cart drive chain had engaged in the direction opposite to the one he intended. The cart began to travel back into the humidifier and trapped Employee #1 between the cart and a wall of the humidifier. He was discovered approximately 10 minutes later. A rescue effort was made from the humidifier approximately 40 minutes after he was first trapped. He suffered burns to his face, chest, and legs.
