Which of the following terms refers to methods used for diverting explosive blasts?

The term that correctly refers to methods used for diverting explosive blasts is deflection. This term encompasses techniques designed to redirect the energy and force generated by an explosive event away from a specific area or structure. These methods are critical in UXO operations as they can minimize damage and the risk of injury to people nearby.

Ventilation, while related to air movement, does not pertain to controlling or diverting explosive force. Similarly, dispersion generally refers to the spreading of materials in a given area, which is not directly about redirecting blasts but rather about the distribution of materials or particles. Containment relates more to enclosing or capturing explosions or hazardous materials rather than diverting their force. Thus, in the context of UXO and explosive management, deflection is the appropriate term for the methods aimed at managing and redirecting blast effects.
