What precaution should be taken when storing explosives regarding temperature extremes?

• A. Store them outside for ventilation
• B. Keep them refrigerated
• C. Store them only in dry conditions
• D. Avoid storing them in temperature extreme locations

Answer: (D)

When storing explosives, it is crucial to avoid temperature extremes because extreme heat or cold can significantly affect the stability and performance of the explosives. Storing explosives in environments with extreme temperatures can lead to degradation of the chemical compounds involved, resulting in reduced effectiveness or even unintended detonation. For example, high temperatures can cause explosives to become more sensitive or unstable, while very low temperatures can lead to crystallization or other chemical changes that could make them unsafe to handle.

Maintaining a controlled and moderate temperature helps ensure that the explosives retain their intended properties and remain safe for use. Thus, proper storage conditions are vital for both safety and operational efficiency in any mining operation where explosives are utilized.
