What is one of the PDI's for the freon?

In the context of the freon distribution system, one of the key aspects of the Post-Deployment Inspection (PDI) is to ensure that the nozzles are effectively placed to manage any potential hazards, particularly regarding waste management. The option that describes two nozzles directed towards the waste bin aligns with the safety protocols that cater to the containment and management of any harmful substances, such as freon, to prevent them from affecting other systems or areas within the aircraft. This setup helps in effectively ventilating and controlling any leaks or spills that may occur, thus ensuring overall safety and compliance with necessary regulations.

The other configurations do not address the critical aspect of targeting hazardous areas like the waste bin. For example, directing nozzles towards the engine or the exit does not provide any real benefit in managing potential hazards associated with freon, and directing all nozzles towards the ceiling fails to focus on critical containment zones. This highlights why the correct answer specifically emphasizes the importance of targeting the waste bin with two nozzles, ensuring a direct approach to managing freon effectively.
