Question

when are signal persons required?
select all that apply.
when an operator does not have full view of the point of operation
when an operator’s view is obstructed in the direction that the equipment is traveling
when either the operator or the person handling the load determines that a signal person is needed

Explanation:

To determine when signal persons are required, we analyze each option:

1. First option (rotated text: "When either the operator or the person handling the load determines that a signal person is needed"): If the operator or load - handler decides a signal person is needed, a signal person is required. This is a valid scenario as their judgment about the need for a signal person is a key factor.
2. Second option (rotated text: "When an operator’s view is obstructed in the direction that the equipment is traveling"): When the operator's view in the travel direction of the equipment is blocked, they can't fully see the path. A signal person is needed to guide the equipment safely, so this is a valid case.
3. Third option (rotated text: "When an operator does not have full view of the point of operation"): If the operator can't fully see the point of operation, they lack the necessary visibility to operate safely. A signal person is required to assist, so this is also a valid scenario.

Answer:

• When either the operator or the person handling the load determines that a signal person is needed
• When an operator’s view is obstructed in the direction that the equipment is traveling
• When an operator does not have full view of the point of operation
