What is the purpose of a safety cap in a fireworks display?

A safety cap in a fireworks display serves the important function of protecting the fuse from damage. This is crucial because the fuse is the component that ignites the fireworks, and any impairment to the fuse can lead to unsafe situations. By safeguarding the fuse from external elements such as moisture or physical impacts, the safety cap helps ensure that the fireworks will fire as intended, thus promoting a safer and more reliable display.

In this context, other options do not align with the specific purpose of a safety cap. For instance, safety caps are not designed to store explosives; they are typically used in the context of ensuring safe ignition and operation. While igniting fireworks safely is essential, this task is accomplished through the proper functionality of the fuse, rather than being related to the role of a safety cap. Similarly, providing sound effects is not relevant to the operation of the safety cap, as sound effects depend on the fireworks themselves and their design, not on protective measures. Understanding the role of safety components like the safety cap is essential for accident prevention in fireworks displays.
