How far should an aerial apparatus be parked from railroad tracks?
Answer: C — 25 feet
An aerial apparatus should be parked at least 25 feet from railroad tracks to ensure a safe distance from potential hazards associated with train operations. This distance allows for adequate space to avoid the risk of being struck by an oncoming train and provides room for the safe deployment of equipment or personnel in the event of an emergency near the tracks. Maintaining this distance is crucial for the safety of both the aerial apparatus and its crew, as well as ensuring that emergency operations can occur without interference from railroad activities.
