What statement is true concerning the door interlock devices associated with a winding drum or traction drive passenger elevator onboard ship?

🔍 Key Concepts

• Purpose of door interlocks on elevators (basic safety function) • Normal elevator operating sequence: doors vs. car movement • What happens if doors are not fully closed or latched on a correctly operating elevator

💭 Think About

• Think about what must be true before any elevator car should be allowed to move: what condition of the doors is safest? • In a fire or shipboard emergency, are interlocks primarily for emergency override or for basic movement safety? • Which options describe a normal, everyday safety function rather than a special emergency-only function?

✅ Before You Answer

• Verify which answers describe normal operation safety (not special emergency mode). • Check which option matches the idea: car movement depends on doors being properly secured. • Eliminate any choice that would let the car move while doors are not in the safest position for passengers.
