Dust explosion hazards at toner cartridge recycling facilities in Japan

摘要

As printing technology develops, toner cartridge particles become smaller and more dangerous. There have been two dust explosion incidents at recycling facilities, in Kanagawa, in Japan, in 2008 due to toner particles. A subsequent study of the hazards of toner particles related to dust explosion revealed that toner particles are dangerous compared with most organic solids, even though they are not classified as hazardous materials in the UN regulation and the Japanese Fire Service Law.
