All actuation seals are required to have what?

• A. Label with date
• B. Tampered seals or anti pilferage seal
• C. Stainless steel hardware
• D. Color-coded tag

Answer: (B)

Actuation devices on ships are safety-critical, so you need a clear indication if someone has opened or tampered with them. The requirement is tamper-evident or anti-pilferage seals on all actuation seals. These seals give a visible sign if the actuator has been accessed, ensuring that any operation of safety-critical equipment is authorized and that the system remains in a verified state until maintenance or inspection is performed. If a seal is broken, it signals the need to check the device before it can be trusted again. While labels, corrosion-resistant hardware, or color-coding can be useful for identification or durability, they do not provide the tamper-evident protection that these seals deliver.
