According to OSHA, what is the standard hand signal to traveling the trolley?

The standard hand signal for traveling the trolley, as recognized by OSHA, involves a palm-up gesture with fingers closed, while the thumb points in the direction of the desired motion. The action includes a distinct horizontal jerk of the hand to convey the command clearly. This signaling ensures that operators are aware of the intended direction of travel, which is essential for maintaining safety around moving equipment. Using this gesture helps to reduce misunderstandings that could lead to accidents or injuries on site.

The other options do not represent the approved hand signal for this specific action. For instance, raising an arm with fingers extended does not indicate the direction of movement for a trolley, and a thumb pointing down isn't consistent with any recognized signal for travel. Similarly, an arm raised to shoulder level doesn't provide the specific directional guidance required for safely operating trolleys. Each of these alternatives could lead to confusion among operators and coworkers, which is why the correct gesture is standardized and taught in training courses.
