Which of the following is NOT one of the five common hazards found in the 2T2X1 career field?

In the context of the 2T2X1 career field, electric shock is not typically categorized as one of the five common hazards. The other hazards—lifting, the use of materials handling equipment (MHE), and noise—are well-recognized risks associated with tasks performed in this job environment.

Lifting is a significant concern because improper techniques can lead to musculoskeletal injuries. The use of MHE facilitates the handling of heavy items, which presents its own set of hazards including the risk of accidents if equipment is not operated properly. Noise is also a known hazard, as prolonged exposure can lead to hearing loss over time if appropriate protective measures aren't taken.

In contrast, while electric shock can certainly pose a risk, it is not one of the primary hazards emphasized specifically within the typical daily operations of the 2T2X1 career field. This distinction highlights that understanding the most common hazards is crucial for maintaining safety protocols in air transportation roles.
