What is the size of the standard explosive?

• A. 1.25" x 8"
• B. 2.0" x 6"
• C. 1.5" x 6"
• D. 1.0" x 10"

Answer: (A)

In blasting practice, knowing the standard explosive size comes from using a common cartridge that crews rely on for consistent performance and safe handling. The traditional, widely used dynamite-style charge is about 1.25 inches in diameter and 8 inches long. That specific size has long been the standard in many training materials and field setups because it provides a predictable amount of energy per stick and is easy to manage and load in typical blasting configurations. So the option that matches 1.25" by 8" aligns with this common standard. Other dimensions exist for specialized uses, but they are not the typical reference size used in standard practice.
