Why should the effectiveness of de-icing fluid be assessed before application?

Assessing the effectiveness of de-icing fluid before application is crucial primarily to ensure that it is both safe for use and effective in preventing ice formation. The safety aspect is important because using a de-icing fluid that is not approved or known to cause harm to surfaces, the environment, or aircraft systems can lead to significant safety risks. Additionally, the effectiveness of the fluid in preventing ice accumulation is essential for maintaining operational safety and efficiency. If the de-icing fluid is not effective, it could result in dangerously icy conditions, which can compromise the functionality of aircraft and lead to hazardous situations.

Evaluating the fluid beforehand allows personnel to choose the right product for the specific environmental conditions they will face, ultimately enhancing safety and operational reliability. Other factors, such as cost and inventory management, while important in a broader context, do not take precedence over the critical need for safety and effectiveness in de-icing operations.
