The M7 Non-Electric Blasting Cap is designed to initiate detonation using a time fuse. This type of detonator relies on a physical fuse that burns at a controlled rate to create a delay before the explosive material detonates. The rationale behind using a non-electric system is primarily safety-oriented; it minimizes the risk of accidental detonation due to electrical interference or stray electrical currents.

In environments or situations where electrical detonation could be hazardous, the M7 serves as a reliable alternative, allowing for precise timing in blasting operations. This timing can be essential for ensuring safety and effectiveness, especially in complex blasting scenarios where multiple charges need to be synchronized.

The other options focus on methods that require electrical components or enhancements to existing explosive techniques, which do not align with the purpose of the M7 Non-Electric Blasting Cap. This cap is specifically tailored to function independently of electrical systems, emphasizing its role in safe and controlled detonations.
