Red Seal Mobile Crane Operator Practice Exam

Checking for clearances and assessing risks is crucial before lifting a load near power lines because it ensures the safety of the operation and prevents accidents or electrocution. Power lines can carry a significant amount of electrical current, and coming too close can pose serious dangers not only to the operator but also to other personnel on site.

By assessing the risks, the operator can identify the distance needed to maintain safety protocols and comply with regulations regarding working near electrical hazards. This process includes measuring clearances and possibly consulting utility companies about the power lines to ensure that no part of the crane—including the boom, load line, or load itself—will infringe on safe working distances.

Increasing boom length or lifting quickly could lead to unsafe practices that may increase the risk of accidents, while disregarding power lines altogether overlooks a critical safety hazard. Effective risk assessment is vital for safe crane operation near any overhead obstacles.
