Is it acceptable to sound both a fuel tank and a water tank with the same sounding tape?

Using the same sounding tape for both a fuel tank and a water tank is not acceptable primarily due to contamination concerns. Fuel and water have different chemical properties, and using a tape that has been in contact with fuel can introduce harmful contaminants into the water tank. This could lead to serious health risks if the contaminated water is consumed or used in any capacity where purity is critical.

Maintaining strict separation between equipment used for different substances, especially those that are as dissimilar and potentially hazardous as fuel and potable water, is essential in safety and operational procedures. This practice ensures that the integrity of the water supply is preserved and that all safety standards are met when handling various materials. The emphasis on cleanliness can mitigate some issues, but it doesn't eliminate the risk of cross-contamination, making the use of different tapes necessary for safe operations.
