Which statement best describes the requirement for actuation seals?

• A. They must be color-coded
• B. They must be replaced yearly
• C. They must have tamper-evident/anti-pilferage seals
• D. They must be transparent

Answer: (C)

Actuation seals are used to protect safety and emergency mechanisms from unauthorized use. The requirement is that they have tamper-evident/anti-pilferage seals so that any attempt to actuate without authorization leaves visible evidence and triggers inspection. In service, a broken or missing seal indicates tampering or unintended operation, and the device must be inspected and the seal replaced before resuming use. Color-coding, yearly replacement, or transparency do not ensure security or integrity; tamper-evident sealing directly addresses the risk of unauthorized actuation.
