The container used for mixing and holding the target material plays a significant role. Using containers different from those recommended by the manufacturer can be dangerous. Improper containers may react with the chemicals, leak, or rupture under pressure. Using a container with too little volume can create excessive pressure during the reaction, leading to a more dangerous explosion. Conversely, using a container that is too large can result in the mixture spreading thinly, potentially causing a misfire or reduced effect.
-
Environmental Factors:
Environmental conditions can influence the mixing process and the target’s subsequent performance. Humidity, for instance, can affect the stability of the oxidizer component, potentially reducing its effectiveness over time. Extreme temperatures can also impact the chemical stability and reaction characteristics. Storing and mixing components in appropriate conditions as recommended by the manufacturer is essential for reliable and safe operation.
Precise mixing is essential for maximizing both the safety and effectiveness of binary exploding targets.

Backstop Selection:
An appropriate backstop is crucial for containing the explosion and preventing projectiles from traveling beyond the designated area. Suitable backstops include thick earthen berms, steep hillsides composed of dense soil or rock, and purpose-built shooting ranges with designated backstop structures. Improper backstops, such as thin wooden fences or metal targets, can allow fragments or the full force of the blast to escape, potentially causing harm or damage. Selecting a backstop capable of absorbing the explosion’s energy and containing any resulting debris is essential for safe operation. For example, a large, compacted dirt mound can effectively absorb the energy of the blast and trap fragments, whereas a thin plywood board would be wholly inadequate.
-
Distance and Safety Zone:
Maintaining a safe distance from the target during detonation is paramount. The manufacturer’s recommendations should always be followed, establishing a minimum safe distance for personnel and any nearby structures. This safety zone accounts for the potential for fragmentation and the blast radius of the explosion.
