More than 95 % of all the terrorist attacks are carried out using the ANFO explosives. The ANFO explosives are explosives made from ammonium nitrate and fuel oil. They can be in three different variants (ammonium nitrate with oil, ammonium nitrate with oil and aluminium powder or ammonium nitrate with oil and TNT). This paper describes analysis of the field test results of ANFO explosives of different types. The efficacy of industrially made and the homemade ANFO explosives is compared and their possible usage in terrorist attacks for the treatment or the damage of critical infrastructure elements is described.

A significant number of airblast test have been carried out with the purpose to characterise and analyse the properties of improvised explosive device (IED) with non-conventional explosives in terms of knowing the effects on people and/or structures. Small devices with 1.5 kg of explosive, initiated with a detonating cord have been studied. Seven different mixtures have been tested with two types of ammonium nitrate AN (technical and fertilizer) in different forms like prills or powder. In some cases, the ammonium nitrate has been mixed with fuel oil while in others, it has been mixed with aluminum. The TNT equivalent based on pressure, impulse, arrival time, positive phase duration and shock front velocity have been calculated and analysed for each mixture. Comparing the field test data obtained with respect to the representation of the UFC 3-340-02 values, it can be seen that the parameters measured are consistent. The IEDs with fertilizer ammonium nitrate do not detonate with the present charge conditions so the shockwave generated is only due to the detonating cord. When using the technical ammonium nitrate, ANFO can partially detonate and generate a potentially dangerous shockwave. Finally, the IED with AN and aluminum produces a TNT equivalent close to one when the technical AN is used.

Landmines and improvised explosive device (IED) explosions induce bodily injuries through the primary, secondary, tertiary, and quaternary mechanisms of blast among civilians, mostly children which results in a complicated, multidimensional injury pattern. If > 80 percent of countries can ensure the security of their borders without using anti-personnel mines, surely India can too. A change in mindset and a change in defense doctrine are needed, as well as an UN-backed world body campaigning against the use of landmines to urge the Indian government to sign a global treaty to ban the weapons. An estimated four to five million anti-personnel mines exist in India, which is the sixth-largest stockpile in the world. Non-state armed groups in the central, southern, northern, and northeastern regions frequently have used anti-personnel mines and improvised explosive devices to target convoys of soldiers and civilians. Using historical, current research and related literature reviews, this study provides description about the types of explosion, the device, pattern of injury, prehospital and emergency department care, and challenges for the disaster plan. Hand amputation is the most common type of upper limb amputation (more common among the 7–18-year age group) and below-knee amputation is the most common type of lower limb amputation. Using these data, a focused disaster response for future attacks has been created. It includes the planning, monitoring, and coordination of all aspects by hospitals and the regional disaster system's plan—“upside-down” triage—the most severely injured arrive after the less injured, which bypass emergency medical services (EMS) and go directly to the nearest hospitals. Details about the nature of the explosion, potential toxic exposures and environmental hazards, and casualty location from police, fire, EMS, health department, and reliable news sources must be recorded.
