Explanation:

You’ll want to prevent laser toner particles from entering your throat and lungs. While laser toner
inhalation has not been proven to cause serious health problems, respiratory tract irritation can
occur with exposure to large amounts of laser toner dust. Laser toner can also contain potentially
hazardous compounds, such as styrene, ethyl benzene, and xylene isomers. Use a mask that filters
both odors and fine particles, such as the ones used for painting and sanding. You can usually find
these at local hardware store
