Hazard Alert
Worker fatally struck by parts ejected from swaging press A worker was using a 600-ton hydraulic swaging press to swage sleeves onto a wire rope sling. The eye
in each end of the sling is formed by splicing the wire rope and placing a steel sleeve over the splice. The sleeve is then placed between two dies within the press to compress the sleeve onto the spliced area. As the worker operated the press, the die assemblies were forcibly ejected out of the press. The worker was fatally injured when struck by these assemblies.
A WorkSafeBC investigation found that the worker had no training or experience on the press. It also established that the dies and die adaptor plates were not properly aligned within the press or secured from moving out of alignment before the worker activated the foot control to close the press. The press had also been set to allow far more pressure than required for the particular swaging job.

Safe work practices:
Provide workers who operate swaging presses with the information, training, and supervision necessary to ensure their health and safety. Ensure operators are familiar with the manufacturer’s manual.
Establish and enforce written safe work procedures for using swaging presses. Include the following:
° Use the press with the proper pressure setting. ° Do not exceed the working load limit for the particular dies. ° Ensure that the dies and die adaptor plates are properly aligned and secured.
Ensure that presses are adequately safeguarded. Perform a risk assessment to determine the most effective safeguarding to reduce the risk of injury. Ensure that a mechanical means is used to prevent dies and die assemblies from inadvertently shifting during swaging.
