3. Toner

Toner is black dust used in laser printers to form the print image. Toner dust has been classified by the FDA a class-A carcinogen. Because of this, care should be taken in the installation, removal, and disposal of print toner cartridges. Toner is so fine that it easily becomes airborne. Minimal respiratory tract irritation and eye irritation may occur with exposure to large amount of toner dust.

·         Never use an ordinary vacuum cleaner on toner. It passes unimpeded through the filters on household vacuums, becoming a true airborne nuisance. If you have a toner spill that cannot be wiped up, call a service technician. They use vacuums with special filters that are designed to trap toner.
