Which of the following is NOT considered a risk control measure when operating a crane near scaffolding?

In the context of operating a crane near scaffolding, risk control measures are essential to minimize the potential hazards associated with such activities. The focus is on implementing strategies that directly prevent accidents or manage risks effectively.

Increased worker surveillance, while it may help monitor safety practices and compliance, does not directly prevent or control risks associated with crane operations. Instead, it reacts to issues rather than proactively preventing them. Effective risk control measures typically include strategies that physically separate or mitigate hazards, such as traffic control, which manages vehicle movement to prevent collisions, barrier installation that physically protects workers and infrastructure, and warning signs that inform all personnel of potential dangers.

In contrast, the correct option highlights that simply increasing surveillance of workers does not inherently eliminate the risk posed by crane operations near scaffolding or ensure safe working conditions. Thus, it fails to align with the core principle of risk control, which is to implement concrete measures that actively reduce or eliminate the identified risks.
