Toxic Phosphorus

Short answer: White phosphorus is a waxy, toxic form of the element that can ignite spontaneously in air at around 30 °C (86 °F). It burns with a bright flame and gives off dense white smoke of phosphorus pentoxide, so it is stored under water.

It is used to make phosphoric acid and other chemicals, and militaries have used it in smoke and incendiary munitions, a use regulated by international law. Contact causes severe burns. The footage shows the chemist from Nile Red handling and burning it.

Video transcript: Toxic Phosphorus: White Phosphorus Can Catch Fire on Its Own in Air

Did you know, white phosphorus is a highly reactive, waxy substance that ignites spontaneously in air at around 30 degrees Celsius or 86 degrees Fahrenheit. It's used in various applications, including military munitions and the production of fertilizers. White phosphorus burns with a bright, intense flame and produces a dense, white smoke of phosphorus pentoxide. It is stored underwater or in inert gases to prevent it from reacting with air. Due to its highly toxic nature, it must be handled with extreme caution, as exposure can cause severe burns and other health hazards. NOW YOU KNOW!
