According to ANSI Z359.4, bucket truck rescue systems are designed for a single person load up to what weight?

According to ANSI Z359.4, bucket truck rescue systems are designed with a specific maximum weight capacity to ensure safety and effectiveness during rescue operations. The standard sets the limit for a single person load at 310 pounds. This capacity is established not only for the safety of the individual being rescued but also to account for the equipment and any additional gear that may be carried during the operation.

When operating in situations where rescue systems are involved, it is crucial to adhere strictly to these guidelines to prevent accidents or failures of the rescue system. Thus, the correct answer reflects the established safety standard aimed at ensuring that individuals working at heights can be safely and effectively rescued in emergencies while also factoring in the necessity for the equipment to perform reliably under specified weights.
