For disruption lines, which metals are permitted for metallic portions?

• A. Aluminum or steel only.
• B. Copper, nickel copper, or copper-nickel.
• C. Plastic or rubber only.
• D. Any metal is acceptable.

Answer: (C)

Disruption lines must be kept free of conductive metal components to reduce electrical hazards on a vessel. Plastic or rubber portions provide insulation and resist corrosion, making them the safe choice for these lines. Metals such as aluminum, steel, copper, or copper alloys conduct electricity and can corrode or spark, creating safety risks, so they are not allowed. That’s why the correct choice is plastic or rubber only.
