Explosive chemicals are substances that can undergo rapid chemical reactions, producing gas and heat, which can lead to an explosion. These reactions often occur when the chemicals are ignited or subjected to shock, causing them to break down quickly and release energy. Common examples include dynamite, TNT, and nitroglycerin. These chemicals are used in various applications, such as construction, mining, and military operations. Safety measures are crucial when handling explosive chemicals, as they can be highly sensitive to temperature, pressure, and physical impact. Proper storage and transportation are essential to prevent accidental detonations.
