For turbine plane of rotation, what indicates exhaust danger?

• A. Red or Black Stripe
• B. Yellow Warning Label
• C. Green Circle
• D. Blue Square

Answer: (A)

Red or black stripes are used as a clear visual warning for exhaust danger on turbine planes of rotation. That distinctive stripe pattern is designed to grab attention quickly and signal a high-risk area where hot gases and moving parts can cause serious injury. Because of this, personnel know to stay clear, use proper PPE, and ensure the engine is shut down and secured before approaching.

Other markings serve different purposes: a yellow warning label signals general caution but not the specific exhaust hazard, while green circles or blue squares are associated with other safety indicators or actions and don’t denote exhaust danger in this context.
