On what grounds claim can be made that smaller mines and quarries are not safe for workers?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) - Unlike larger companies, smaller companies do not cover open holes.
Smaller mines and quarries may lack the resources and infrastructure to implement safety measures such as covering open holes, which can pose significant risks to workers' safety. Larger companies typically have more resources and stringent safety protocols in place to mitigate such hazards.
