When must emergency response strategies for mines rescue be ready for implementation?

Emergency response strategies for mines rescue must be ready for implementation whenever a person is below ground. This is because the underground environment in mines presents unique hazards and risks, making it essential that rescue plans are in place at all times when personnel are on site. Preparedness is crucial in ensuring rapid and effective response to any emergencies that may arise, given the complexities and potential dangers involved in mining operations.

Having these strategies in place when personnel are underground ensures that rescue teams can act immediately if an incident occurs, which is vital for the safety and well-being of workers. Regular drills and checks are indeed important, but the foundational requirement is that strategies are actionable whenever individuals are at risk underground, meaning they are ready to translate into real-time action at a moment's notice. This proactive approach helps to minimize the risk to miners and enhances overall safety at the operation.
