Abstract: Employee #1, a helper, and a coworker, the machine operator, were working on a tenter at a fabric dyeing plant. The tenter is a machine that irons out wrinkles on rolls of fabric after the fabric has been dyed. The coworker was at his work station in front of the controls, and Employee #1 was at the backside of the rollers where the fabric feeds into the machine. Employee #1 was setting up the machine by pulling fabric through the rollers. The machine was stopped while Employee #1 was feeding the rollers. The coworker, who could not see Employee #1, then turned on the machine. He heard Employee #1 yelling, looked over, and saw him waving his arms. The coworker turned off the machine, attempted unsuccessfully to extract Employee #1, and summoned help. Employee # 1 sustained a fractured tibia and fibula in his left leg. The main causal factor in this accident was the employer's failure to stop, de-energize, or lockout the machine to prevent inadvertent movement during set-up operations.
