Why is it important to monitor the temperature of de-icing fluids?

Monitoring the temperature of de-icing fluids is crucial primarily because their effectiveness can diminish at low temperatures. De-icing fluids typically have a specific temperature range within which they perform optimally, and if the temperature falls below this range, their ability to melt ice and prevent ice formation can be significantly reduced. This means that if the fluids are not maintained at the proper temperature, they may not adequately perform their de-icing function, increasing the risk of unsafe conditions on surfaces like runways and roadways.

In contrast, while there are considerations regarding high temperatures affecting fluid performance, the primary concern in de-icing practices revolves around ensuring that fluids remain effective in low-temperature conditions, where ice and frost formation is a significant hazard. Monitoring temperature ensures that the fluids are used in conditions where they can provide optimal performance.
