Final answer:
Proper training is not considered a crane-related hazard, while overloading, lack of maintenance, and unsafe operating conditions are. Proper training is a safety measure to prevent crane-related accidents.
Step-by-step explanation:
The correct answer to the question "Which one of the following is NOT considered to be a crane-related hazard?" is Proper training. Crane-related hazards typically include:
- Overloading, which refers to when a crane is burdened with weight beyond its capacity, leading to potential mechanical failure or tipping.
- Lack of maintenance, where insufficient or improper maintenance may cause unexpected malfunctions, leading to dangerous situations.
- Unsafe operating conditions, which involve operating a crane in dangerous weather or without regard to surrounding obstacles and site conditions.
In contrast, Proper training is not a hazard. Rather, it is a preventive measure that helps reduce the risk of accidents associated with crane operations by ensuring that operators are equipped with the necessary knowledge and skills to operate cranes safely.
