How many rescue teams are required when more than 10 but fewer than 50 persons are employed underground?

• A. No teams required
• B. One team
• C. Two teams
• D. Three teams

Answer: (B)

When more than 10 but fewer than 50 persons are employed underground, the requirement is to have one rescue team available. This regulation is designed to ensure that there is adequate preparedness for emergency situations, allowing for a prompt response to incidents that may occur underground.

Having one dedicated rescue team helps to ensure that trained personnel are on standby and can effectively execute rescue operations if necessary. This is crucial for the safety of all underground workers, as it can significantly reduce the response time during emergencies. The establishment of a single team is sufficient for this range of employees, considering the operational dynamics and risks associated with mining environments.

More teams are not required because that could lead to unnecessary resource allocation and redundancy, while fewer teams would not meet the safety regulations established to protect underground workers.
