Does Nonel tubing resist the penetration of oil in ANFO?

• A. Yes, it is completely impervious
• B. No, it can be penetrated by fuel oil
• C. Only if stored properly
• D. No, but it can withstand exposure for a week

Answer: (B)

Nonel tubing is designed specifically for use in blasting and is known for its ability to resist penetration by various substances. However, it is not completely impervious to all types of fluids, particularly fuel oils that are commonly used in ANFO (Ammonium Nitrate Fuel Oil) mixtures. Fuel oils can penetrate Nonel tubing, which is a vital consideration when handling and storing explosives in proximity to various potential contaminants.

The choice that indicates that Nonel tubing can be penetrated by fuel oil underscores the importance of being aware of the conditions under which the tubing is used. It emphasizes the need for proper handling and storage of materials to avoid compromising the tubing's integrity. Understanding this characteristic of Nonel tubing is essential for ensuring safety and efficacy in blasting operations, as penetration could lead to hazardous conditions.

In contrast, the other options suggest incorrect levels of impermeability or conditions that do not align with the known properties of Nonel tubing, thus reinforcing that while the tubing offers significant resistance, it is not entirely immune to fuel oil penetration.
