What are the major safety concerns of a handbrake?

The correct choice highlights that all listed safety concerns regarding a handbrake are significant. Each issue presents a distinct risk that can impact the safety of individuals working around or using the handbrake.

The concern about finger squishing under the nosebar addresses the potential for hand injuries when the handbrake is engaged or released. This is a crucial consideration as workers’ hands can inadvertently get caught, leading to severe injuries.

Counterbalances hitting people is another important safety issue. When a handbrake is malfunctioning or improperly maintained, counterbalances may unexpectedly swing or fall, posing a danger to anyone in close proximity.

Lastly, the risk from the operating handle hitting people is significant as well. If the handle is moved abruptly or without proper caution, it can strike individuals nearby, leading to injuries.

Recognizing that all these points represent valid and serious safety concerns emphasizes the need for proper training, awareness, and safety protocols when using and maintaining handbrakes in any setting.
