Which of the following is NOT a recommended practice near engine intakes?

• A. Stand directly in the engine intake area to observe airflow
• B. Do not enter engine intake areas when engines are running
• C. Keep distance; do not pass in front of or behind a running engine; stay out of engine intake areas
• D. Stand clear of the engine while it is operating

Answer: (D)

Near engine intakes, the safest approach is to stay out of the intake area, especially when the engine is running. The intake can generate powerful suction that can pull clothing, tools, or body parts into the engine, and debris can be ingested, causing injury or damage. Standing directly in the intake area to observe airflow is not a safe practice for this reason.

The other practices align with safety: avoid entering intake areas when engines are running, keep a distance and avoid passing in front of or behind a running engine, and stay well clear of the engine while it is operating. These precautions help prevent severe injuries from suction, moving parts, heat, and noise. If you need to assess airflow or conditions, do so from a safe, outside position or using non-contact methods.
