Which of the following accidents can be avoided if employers make sure that no one is under lifting objects?

The focus of ensuring that no one is under lifting objects is primarily associated with preventing injuries related to falling objects. If someone is positioned beneath a load being lifted by equipment such as a forklift, any failure or accidental release of that load can lead to severe injuries or fatality due to the load falling. By implementing strict protocols that prevent personnel from being in the danger zone when objects are being lifted, employers significantly reduce the risk of these potentially catastrophic incidents.

Crushing objects concern scenarios where heavy items, roles, or equipment may press against a worker; however, the immediate threat from lifting operations is best connected to falling loads, making this the most relevant safety concern in this context. Other options, while they represent legitimate safety hazards, do not directly relate to the risks involved with lifting operations in the same way. Addressing the training and safety measures around lifting practices effectively targets the prevention of injuries from falling objects.
