Why is it necessary to ensure that explosives are kept fresh?

• A. They improve in quality over time
• B. They become dangerous and deteriorate with age
• C. They are easier to transport when fresh
• D. They need to be replaced every year

Answer: (B)

It is necessary to ensure that explosives are kept fresh because they can become dangerous and deteriorate with age. As explosives age, their chemical stability can decrease, leading to potential instability or an unexpected reaction when they are eventually detonated. Factors such as moisture absorption, temperature changes, and exposure to air can affect the integrity of the explosive materials. This deterioration can manifest in reduced effectiveness, unpredictable performance, or increased sensitivity to accidental detonation. Therefore, maintaining the freshness of explosives is crucial for safety during handling, storage, and use in mining operations. Regular checks and timely replacement of aged explosives help ensure both the effectiveness and safety of blasting operations.
