What safety measure is associated with using Nonel assemblies?

• A. Always checking for moisture
• B. Using it only indoors
• C. Keeping it away from heat
• D. Testing it for stability

Answer: (A)

The safety measure associated with using Nonel assemblies is primarily focused on always checking for moisture. Nonel (Non-Electric Initiation System) assemblies are designed for use in explosive applications, and moisture can significantly affect their reliability and performance. If moisture penetrates the assembly, it can lead to initiation failure, misfires, or unintended detonations. Therefore, ensuring that these assemblies are protected from moisture is a critical safety measure to maintain their effectiveness and avoid accidents.

In contrast, while keeping Nonel systems away from heat or testing them for stability might also be important, the direct and specific concern with moisture makes it the most crucial safety measure. Using Nonel assemblies exclusively indoors is not a standard safety requirement, as they can be used in various environments if properly managed.
