During a suspected terrorist event, which of the following is a warning indicator responders should be alert for?

• A. several people with minor injuries.
• B. placard containers.
• C. public gathering.
• D. secondary devices.

Answer: (D)

The main idea is that responders must stay alert for the possibility of a secondary device, because attackers often set additional explosives to harm responders who arrive after the initial incident. This warning indicator is tied directly to the tactic of using follow-on devices to maximize harm and complicate rescue efforts, so spotting or suspecting a second device should prompt immediate actions to protect yourself and others and to call in specialized teams. In practice, you’d be vigilant for signs like suspicious objects in or near routes you and others will use to move away from the scene, unattended or out-of-place items, or any device that seems added or out of place after the first incident. Recognizing this possibility helps you create a safer stance for responders and civilians, slowing or redirecting entry until the area can be cleared by a bomb squad or EOD teams. While events at a scene can involve multiple minor injuries, hazardous-materials concerns, or large crowds, these factors alone don’t indicate a deliberate follow-on threat designed to target responders. They don’t carry the same specific warning value as the presence or suspicion of a secondary device.
