What situation can be dangerous when working around concrete mixer trucks?

When working around concrete mixer trucks, it's essential to be aware of the various operational hazards that can arise. Both the movement of chutes side to side and the truck itself moving forward pose significant dangers.

When chutes are moving from side to side, they can swing unpredictably, leading to the risk of injury to workers nearby. If someone is in the path of a moving chute, they could be struck or have concrete splashed on them unexpectedly.

Similarly, when the truck is moving forward, it may not be immediately apparent to all workers in the vicinity. The potential for the truck to encroach on the space where workers are standing increases the risk of being run over or caught. Visibility issues for the driver in certain positions can exacerbate this danger, highlighting the importance of maintaining a safe distance from the vehicle.

Thus, when both the moving chutes and the forward motion of the truck are considered as hazardous situations, the selection of either of those options reflects the real risks present during operations with concrete mixer trucks.
