Which of the following is NOT a characteristic of non-explosive impulse cartridges?

The statement indicates that non-explosive impulse cartridges do not have a higher risk of fire. This aligns with their design and usage compared to explosive cartridges. Non-explosive impulse cartridges are specifically engineered for use in situations where sound and recoil are minimized, making them ideal for training purposes. They utilize a method that generates a lower noise level, thereby avoiding the loud bangs associated with traditional ammunition.

Additionally, their reliability comes from simplified mechanisms without the complexities of explosive materials, which can be more prone to failure or misfire. Consequently, they present a lower fire risk since they do not contain explosive components that could ignite. In contrast, traditional ammunition inherently carries a higher risk of fire due to the explosive materials used. Therefore, identifying that non-explosive impulse cartridges do not have a higher risk of fire accurately reflects their safer operational characteristics.
