What is a key requirement for the storage of petroleum, oil, and lubricants (POL)?

The storage of petroleum, oil, and lubricants (POL) is critical in aviation maintenance due to safety and environmental concerns. A key requirement is that these substances be temperature controlled and ventilated.

This is essential because controlling the temperature prevents the POL from reaching conditions that may lead to combustion or degradation of the materials. Adequate ventilation also ensures that any volatile fumes do not accumulate, which could pose a fire hazard or affect air quality in storage areas. Proper ventilation strategies help disperse harmful vapors, further safeguarding personnel and the facility.

In contrast, other storage methods can increase risks. For instance, storing POL outdoors may expose them to elements that can affect their integrity and safety, while accessibility for personnel without safety considerations can lead to unintended exposure or accidents. Additionally, simply locating POL far from other materials may not address the fundamental issues of temperature and ventilation that directly contribute to safe storage practices.
