What materials are often used in improvised explosives?

The usage of fertilizers, chemicals, and commercial explosives in improvised explosives stems from their availability and the chemical properties that make them conducive for explosive reactions. Fertilizers, particularly those containing ammonium nitrate, can be combined with fuels or other substances to create powerful explosive devices. Chemicals often have reactive capabilities that can lead to detonation or a rapid expansion of gas when combined correctly. Commercial explosives are designed specifically for demolition and construction purposes, allowing for a predictable and effective explosion when misused.

Understanding the makeup of improvised explosives is crucial for EOD technicians, as it helps them identify potential threats and develop safe methods for neutralization or disarmament. This knowledge highlights the importance of managing and regulating access to these readily available materials to prevent malicious use.
