Safety features of Stun Grenades

• A. Equipped with 1 safety feature
• B. Equipped with 2 safety features
• C. Equipped with 4 safety features
• D. Equipped with 3 safety features

Answer: (D)

Stun grenades are built with multiple safeguards to prevent any accidental detonation during handling, transport, or unintentional arming. The number of safety features commonly incorporated is three, reflecting layers of protection that must be overcome in a deliberate sequence by a trained operator.

First, there is a safety pin that physically prevents the device from arming. Until the pin is removed, the firing mechanism cannot be engaged. Second, a safety lever (often called the spoon) must be held in place to keep the grenade from arming; only when the lever is deliberately manipulated and released does the arming sequence begin. Third, an internal safety mechanism within the fuze or a secondary tamper/arm safety prevents ignition from occurring unless the prior steps are completed correctly and a timed delay element is activated. This combination ensures that the device cannot detonate due to a simple shock, drop, or incidental contact, and it provides a predictable, controlled arming process.

So, the design relies on three independent safeguards to minimize risk and ensure that effective deployment happens only under controlled conditions.
