Engines are a high-risk zone due to ingestion hazard and account for what percent?

• A. 4%
• B. 13%
• C. 7%
• D. 20%

Answer: (B)

Engines create a high-risk zone because the intake area can pull in foreign objects or even people when an engine is running, causing severe injury or catastrophic damage. The percent 13% indicates that about one in eight ground-incidents involving ingestion hazards are linked to engine areas, highlighting how significant this risk is across ramp operations.

In practice, this means strict distance rules around intakes, verbal and visual clearances before engine start, and adherence to ground crew procedures to prevent anything from getting near the intake during operations. The other percentages would not align with how often engine ingestion-related incidents appear in safety data, so 13% is the best reflection of its share of risk.
