Which option correctly lists all four PIES components in their standard order?

• A. Power Source, Initiator, Explosive, Switch
• B. Power Source, Initiator, Switch, Explosive
• C. Initiator, Power Source, Explosive, Switch
• D. Power Source, Explosive, Initiator, Switch

Answer: (A)

This item tests your recall of a four-part model used in safety training to describe how a device is structured and how its components interact in sequence. The established order is designed to mirror the flow of energy or action through the system, from the initiating stages to the final effect, and remembering that exact sequence helps responders and exam takers understand how such a device would operate in a real scenario. The best answer is the one that matches the standard order taught in your course materials, because this order is what your training hinges on for consistent interpretation and safe handling. If the four parts feel familiar but the order escapes you, review the section in your notes that lays out the sequence and practice reciting it until it comes to mind in the correct order.
