NFPA Code for Fireworks Display (NFPA 1123) Practice Exam 2025 - Free NFPA 1123 Practice Questions and Study Guide

The component used to ignite fireworks at outdoor displays is a portfire. A portfire is a type of slow-burning fuse that allows for a safe and controlled ignition of the fireworks. It is designed to provide a steady flame that burns for a specific duration, giving the operator time to ignite the fireworks from a safe distance.

The use of portfires is crucial for safety, as they minimize the risk of accidental ignitions that could arise from handling open flames or other ignition sources. This method ensures that the fireworks are ignited at the appropriate time, creating a coordinated display that is essential for audience enjoyment and safety during events.

In contrast, a mortar rack serves as a holder for aerial shells, black powder is a propellant and not an ignition source on its own, and a ready box is used for storing fireworks or initiating devices but is not for ignition. The selection of a portfire is directly aligned with best practices as outlined in NFPA 1123, which emphasizes safety and effective control over fireworks ignition procedures.
