For exceptional two man descent, what weight limit does ANSI Z359.4 specify for bucket truck rescue systems?

The correct weight limit specified by ANSI Z359.4 for bucket truck rescue systems in the context of exceptional two-man descent is 440 lbs. This standard acknowledges the necessity for both the rescuer and the person being rescued to be safely accommodated within the constraints of the system, which includes the weight of the equipment and potential variables during the descent.

This weight limit helps ensure that the rescue system has been tested and is capable of safely supporting that combined load, thereby reducing the risk of system failure during an emergency. Maintaining compliance with this standard is crucial for the safety of both the rescuer and the individual being rescued, as exceeding the weight limit could lead to catastrophic consequences in a high-risk environment. The specified limit is a crucial factor in planning and executing safe rescue operations.
