Girish Linganna
A chemical, called ‘white phosphorus’, is often used to manufacture artillery shells, rockets and bombs. When exposed to oxygen, it ignites and burns at a very high temperature of 815°Celsius. This reaction creates a bright light and thick smoke, useful in military operations. However, this incendiary chemical can result in grievous injuries to any person who comes into direct contact with it. White phosphorus is not considered a chemical weapon because it works mainly through heat and flames rather than toxicity. It can be delivered using felt wedges, or small pads, soaked in phosphorus and has a distinctly ‘garlic-y’ smell.
How Exactly is White Phosphorus Used?
White phosphorus is mainly used to shield the army’s activities on the ground. It creates a smokescreen, both during the day and at night, to conceal the movement of troops. Additionally, it disrupts infrared optics and weapons tracking systems, helping protect military forces from guided weapons, such as anti-tank missiles.
When white phosphorus explodes in the air, it covers a larger area compared to when it explodes on the ground. This makes it useful for hiding large troop movements. However, this also means that its burning effects spread over a wider area, which increases danger to civilians in such crowded places as Gaza. On the ground, in case of a white phosphorus explosion, the danger zone is more concentrated as the smokescreen persists for a longer time. The duration the smoke stays in the air depends on the weather, so it is hard to predict exactly how long it will last.
