Munitions Firefighting Practice Exam

Which statement is true for both JP-10 and liquid hydrazine?

1. They are both non-toxic.

2. They can be extinguished with water.

3. Their combustion produces poisonous gases.

4. They do not produce smoke when burnt.

The correct answer is: Their combustion produces poisonous gases.

The correct answer highlights that the combustion of both JP-10 and liquid hydrazine produces poisonous gases. JP-10, primarily used as a fuel in military aircraft and missiles, can release harmful compounds, such as carbon monoxide and nitrogen oxides, upon combustion. Liquid hydrazine, known for its use in rocket propulsion, also generates toxic gases, including ammonia and nitrogen compounds when it burns. Understanding this is crucial for safety, especially in firefighting scenarios, as both materials present serious health risks during combustion. Recognizing the toxic nature of the products formed helps responders prepare adequately for hazardous situations involving these substances. Regarding the other statements, they do not hold true for both JP-10 and liquid hydrazine. For instance, both substances are toxic, and while certain firefighting methods may apply to one, they might not work effectively for the other. Additionally, the statement about smoke production does not accurately reflect the behavior of these substances when ignited, as both can produce significant smoke.
