What should be done immediately after identifying a contaminated area?

Immediately after identifying a contaminated area, it is crucial to inform the Pilot-in-Command (PIC) and ground personnel. This action is essential because the PIC is responsible for the overall safety of the flight and must be made aware of any potential hazards that could impact the aircraft, crew, or passengers. Informing ground personnel is equally important as they may need to take additional measures to address the contamination, such as ensuring that appropriate safety protocols are followed or coordinating cleanup efforts.

Taking swift action to communicate the situation allows for an effective and prompt response, helping to mitigate risks and maintain a safe environment for everyone involved. This approach reflects a commitment to safety and adherence to established protocols, which is vital in aviation operations.
