How can an assembler prevent a torque reaction injury?

The correct answer focuses on disengaging the tool once the specified torque is reached. This action is essential for preventing torque reaction injuries because it minimizes the risk associated with sudden or unexpected torque reaction from the tool. When a fastener is tightened, the tool generates a reactive force that can lead to a sudden movement or jerk, potentially causing injury to the assembler if they do not properly disengage the tool at the correct moment.

By disengaging the tool as soon as the desired torque is achieved, the assembler can avoid excess force being exerted, which could lead to loss of control or strain. This practice aligns with safety protocols that advocate for proper torque management to protect workers from harm.

Other choices, while they may have some validity, do not directly address the prevention of torque reaction injuries as effectively as disengaging the tool does. Continuing to apply torque could lead to over-tightening and increased risk of injury due to backlash or jerking motions. Using both hands may help in controlling the tool better, but it does not eliminate the risk associated with reactive forces if the tool is not disengaged appropriately. Wearing weightlifting gloves might provide additional grip but does not address the core issue of managing torque reaction hazards effectively.
