Jet Engine Blast Factors include which factor combination?

• A. Temperature (700+)
• B. Velocity
• C. Humidity
• D. Temperature (700+) and Velocity

Answer: (D)

Jet engine blast hazards come from the energy carried in the exhaust, which is driven by heat and speed. A high exhaust temperature, such as 700+ degrees, means a large amount of thermal energy that can cause burns and heat damage. A high exhaust velocity adds strong momentum and potential overpressure, extending the reach of the blast and its effects on nearby objects and people. Humidity can influence how the plume mixes with the surrounding air, but it doesn’t define the blast’s energy or impact in the same way temperature and speed do. Since the hazard is governed by both intense heat and rapid jet motion, the factor combination that best describes jet engine blast is Temperature (700+) and Velocity.
