Which opening is used for maintenance access and is commonly referred to as a hatch?

• A. HATCH
• B. SCUTTLE
• C. BULKHEAD
• D. DECK

Answer: (A)

The opening used for maintenance access is called a hatch. A hatch is a deck or overhead opening fitted with a lid or cover, designed to be opened so crew can reach spaces below—machinery, stores, and other compartments—during maintenance, inspection, or access tasks. A scuttle is a smaller opening, often circular, mainly for ventilation or light and not the primary entry point for routine maintenance. Bulkhead refers to a vertical wall, and deck is the surface itself, not an opening. So for maintenance access, the hatch is the standard term.
