When cuffs are applied, what is the standard practice regarding locking?

• A. They must be double locked unless the environment makes it tactically unsafe.
• B. They should be single locked.
• C. Locking is optional.
• D. They should be triple locked.

Answer: (A)

The essential idea is to prevent the restraints from tightening further after they’re secured. When cuffs are applied, you want the locking to be permanent against any tightening as the person moves or swells, which protects circulation and reduces the risk of injury or an attempt to escape.

Double locking adds a secondary mechanism that locks the pawl in place so the cuffs cannot cinch tighter, even if the wearer pulls, struggles, or shifts. This makes the restraint safer for the person and easier to manage for the handler. If you only have a single lock, the cuffs can still tighten under stress, which can cause pain, numbness, or injury and can complicate later removal.

The triple-lock concept isn’t a standard practice in this context, so it isn’t used. There are occasional tactical scenarios where speed is prioritized or movement is critical, and in those rare cases the standard double lock might be deemphasized temporarily, but the default and best practice is to apply a double lock as soon as the cuffs are locked.
