Which action is prohibited regarding the POC air intake and outlet?

• A. Block the POC air intake filter and the outlet
• B. Open the POC case
• C. Place POC on the floor
• D. Leave POC unattended

Answer: (A)

Unobstructed airflow through the POC’s air intake and outlet is essential for cooling and proper operation. Blocking either path restricts airflow, which can cause overheating, reduced filtration effectiveness, and potential malfunctions or safety hazards. Because keeping air moving through the POC is a basic safety and performance requirement, this action is prohibited. The other actions may be allowed or context-dependent in maintenance or safety guidelines, but the key safety concern here is preventing airflow obstruction.
