Which term describes debris expelled by a pyrotechnic device capable of causing injury?

• A. Aerial shells
• B. Fallout Area
• C. Hazardous Debris
• D. Lance

Answer: (C)

The main idea here is recognizing the term used for dangerous fragments that can injure people when a pyrotechnic device fires. The debris expelled during firing—like sharp fragments, hot embers, and unburned material—falls into a category called hazardous debris. This label signals that those fragments pose real injury risks, so safety plans emphasize controlling where they can land and who must be kept clear, using barriers and establishing safe fall-out paths.

Aerial shells describe the devices that create effects in the sky, not the debris themselves. The fallout area refers to the zone where debris may land, not the debris’s inherent danger. A lance is a different device or effect and does not describe the debris. So identifying the debris as hazardous debris best captures both the danger and the safety actions needed.
