How many rescue teams are required at an open pit mine employing more than 25 persons per shift?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (A)

In the context of safety regulations for open pit mines, particularly those employing more than 25 persons per shift, it is established that at least one rescue team must be on site to ensure rapid response in case of emergencies. The requirement for a single team is based on the need to quickly address potential incidents, such as accidents or other safety risks that might arise in the operation of the mine.

This arrangement allows for efficient management of emergencies, as a single rescue team can be adequately trained and equipped to handle various scenarios, given that the number of workers surpasses the threshold of 25. The rationale behind having just one team, rather than multiple teams, is to balance the costs and training resources with the level of risk present.

In situations where the operation scales or risk factors increase significantly, it might warrant consideration for additional teams. However, under current guidelines, one properly trained and resourced rescue team is deemed sufficient to ensure a prompt emergency response in this context.
