🔍 Key Concepts

• SOLAS watertight integrity requirements for cargo spaces • Differences between type of door, method/location of operation, and emergency/manual operation • What SOLAS is most concerned with during a flooding emergency

💭 Think About

• Ask yourself: in an emergency with loss of power or control from the bridge, what must still be possible at each watertight door? • Consider which options describe an absolute requirement for every door versus something that might only apply to certain designs or be optional. • Think about whether SOLAS is more focused on how you move the door (sliding vs other types) or on ensuring you can still control it safely under all conditions.

✅ Before You Answer

• Verify in SOLAS whether sliding doors are the only permitted type in cargo spaces or if other approved designs are allowed. • Check if bridge-only control is mandated, or if local control at the door is also required. • Confirm whether manual (hand) operation is required for each watertight door in case of power failure.
