Toner Safety

Toner has been classified by the International Agency for Research on Cancer as a Group 2B carcinogen, meaning that it is possibly carcinogenic to humans due to one of the main components of black toner: carbon black. Toner is also considered a possible carcinogenic because it is in powder form, thus making it easy to inhale, and easily able to coat the respiratory surfaces. It is highly recommended to use safety measures when handling toner.

  1. Spilled Toner

    • The particles of powder toner are very fine and can stay in the air for some time. To diminish the amount of toner particles in the air, vacuum spilled toner dust or wipe it with a damp cloth; don't sweep or brush it, as this may result in more powder particles flying into the air.

    Refilling Cartridges

    • Although toner is considered low hazard on skin, it is better to wear disposable or household rubber gloves when refilling cartridges to prevent any amount of toner being absorbed through skin. A dust mask is also recommended to avoid possible inhalation of toner particles.

    Washing Toner

    • If toner comes in contact with skin, wash with soap and cold water. Hot water causes toner particles to become sticky and harder to wash away. This applies to skin and clothes. If toner gets into your eyes, rinse with water for at least 10 minutes and consult a doctor if necessary.
