What is prohibited when the air temperature is below 3°C?

When air temperature drops below 3°C, spilling any water on aprons is prohibited primarily due to safety concerns. Water can freeze at low temperatures, creating ice patches that are hazardous for both vehicle operators and pedestrians on the airside. This can lead to slips, falls, and accidents, which is why strict measures are in place to prevent the introduction of water onto surfaces that could freeze.

Operating vehicles on taxiways or using heating equipment can still be done under controlled and safe conditions. Additionally, cleaning of surfaces may occur using methods that do not involve the introduction of water, such as using dry cleaning techniques or special products designed for low temperatures. Understanding these regulations helps maintain safety and operational integrity in cold conditions at the airport.
