Alhambra, CA – A foundry worker lost both legs last August after a coworker re-energized the machine he was working in. Alhambra Foundry has been fined $283,390 for federal workplace safety and health violations including lack of permit-required confined space program, inadequate machine-specific lockout procedures, missing accident prevention signage, and not having a confined space attendant monitoring his entry.
According to federal safety regulators, two Alhambra Foundry employees were cleaning and unblocking a 38-feet-long auger screw conveyor at the bottom hopper of an industrial air filtration device without effectively locking out the equipment. After the cleaning was done, one of the workers re-entered the 20-inch square opening to retrieve a work light from inside the confined space. Unfortunately, at that same time a maintenance worker 45 feet away energized the equipment to perform a test. The moving auger screw pulled the worker into the screw conveyor and both of his legs had to be amputated in order to get him free of the machine.
The Cal/OSHA Chief stated that “sending a worker into a confined space is dangerous, especially inside machinery that can be powered on at any time…Employers must ensure that machinery and equipment are de-energized and locked out before workers enter the space to perform operations involving cleaning and servicing.”
In their investigation, Cal/OSHA found that the screw conveyor was not de-energized and locked out before workers entered the hopper, and accident prevention signs were not placed on the controls. Alhambra Foundry lacked specific procedures for de-energizing and locking out the equipment and additionally, the worker re-entering the hopper was not monitored by a confined space attendant.
Unfortunately, Alhambra Foundry was cited for similar violations eight years ago and therefore were issued a willful serious accident-related violation for failing to take appropriate measures to protect workers performing cleaning and servicing operations.
