Plastic covers shall not be used in any exterior portion of the airport except...

Plastic covers are typically restricted in exterior areas of the airport due to concerns about safety, visibility, and the potential for debris in operational zones. However, there is an exception that allows the use of plastic covers specifically for covering cargo pallets or containers that are completely netted. This practice is permissible because netting ensures that the cargo remains secure and minimizes the risk of plastic materials becoming dislodged and posing hazards to airport operations or the surrounding environment.

Using plastic covers in this context helps with protection against environmental factors such as rain or wind without compromising safety protocols. The netting provides a secure method to contain the cover, reducing the risk of it becoming airborne and causing disruptions at the airport.

Other circumstances around the use of plastic covers, such as those related to vehicles, sensitive equipment, or passenger luggage, may not meet the same stringent safety requirements, which is why they do not qualify for this specific exception.
