When avoiding turbine engines how far away should you stay from the intake and from the exhaust (at idle)?

• A. 25 ft from intake and 100 ft from exhaust
• B. 5 ft from intake and 20 ft from exhaust
• C. 50 ft from intake and 50 ft from exhaust
• D. 200 ft from intake and 300 ft from exhaust

Answer: (A)

The main idea is safety distances to avoid two engine hazards: suction at the intake and jet blast from the exhaust. Even at idle, a turbine can pull nearby objects toward the intake, which can cause injury or damage if you’re too close. The exhaust blasts out hot gases and debris behind the engine, so staying far enough away protects you from heat, noise, and flying debris. That’s why the recommended distances are about 25 feet from the intake and 100 feet from the exhaust. 25 feet gives a safe buffer against ingestion and contact with the intake; 100 feet provides ample clearance to avoid the blast and any debris kicked up by the engine. The other options place you too close to the intake or exhaust or are not practical in most operations, which is why they aren’t the best choice.
