When there are 50 or more workers employed underground, how many rescue teams are needed?

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

Answer: (B)

When there are 50 or more workers employed underground, the requirement is to have two rescue teams available. This is based on safety regulations that aim to ensure swift and effective response capabilities in case of an emergency. Having two teams allows for redundancy and preparedness; one team can be deployed for rescue efforts while the other can stand by in case additional assistance is needed or if the first team requires rotation. This is crucial in maintaining the safety of the employees and providing immediate support during incidents, thereby ensuring that all workers are protected.

The requirements for rescue teams are typically outlined in mining safety regulations, which emphasize the need for adequate safety measures based on the number of personnel present underground. Regulations generally stipulate that as the workforce increases, so must the resources allocated to emergency response teams, ensuring proper capability to manage potential emergencies effectively.
