What emergency procedures must a conductor be familiar with?

A conductor must be well-versed in evacuation protocols, emergency communication, and first aid because these procedures are crucial in ensuring the safety of passengers and crew during emergencies. In a situation where immediate action is necessary, such as a fire, medical emergency, or other hazardous situations, the conductor plays a vital role in directing the flow of events.

Evacuation protocols provide a clear plan of action, ensuring that all passengers can safely exit the train or transit area. Emergency communication training equips the conductor to effectively communicate necessary information to passengers and relay critical information to emergency responders. First aid knowledge empowers the conductor to provide immediate assistance to injured or ill passengers until professional medical help arrives.

These skills are fundamental to maintaining safety and order during emergencies, whereas the other options, though important in their own right, do not directly contribute to emergency response preparedness. Routine maintenance checks, customer service training, and operational route changes are essential aspects of a conductor's role, but they do not address the immediate needs and actions required during emergencies.
