Preventing indoor air problems from markers

Markers are becoming more common as dry erase boards replace chalkboards. Markers are also used on flip charts and overhead transparencies. The problem with markers, especially permanent ones, is that they contain high amounts of solvents. Though this means they evaporate easily, that means the vapors from these markers quickly get into the air where they can be breathed in deep into the lungs.

Common Solvents Emitted

  • Acetate

  • n-Butanol

  • r-Butyrolactone

  • Diacetone Alcohol

  • Ethanol

  • 1-Methoxy-2-propanol

  • 2-Methoxyethanol

  • n-Propanol

  • Xylene

Under the U. S. Labeling of Hazardous Art Materials Act (LHAMA), all art materials sold in the U. S. must be evaluated and labeled, if necessary, for chronic toxicity according to the chronic hazard labeling standard, ASTM D 4236. This act requires art and craft materials manufacturers to evaluate their products for their ability to cause chronic illness and to place labels on those products that provide health and cautionary information and safe use instructions.1

Although most markers and pens are certified and labeled, it is the responsibility of the consumer to read the hazard information and safe use instructions provided on the label.

Preventing Indoor Air Quality Problems From Markers 

  • Many companies are now offering "non-toxic," "low-odor" and/or "low-VOC" markers to their customers.

    • Use crayons or other marking devices that do not emit solvents.

    • Use markers that do not emit many vapors.

  • Use computers.

  • Put the caps on markers when you are not using them.

  • DO NOT USE markers that give off fruit or other pleasant scents. These emit chemical fragrances and encourage people, especially children, to sniff these chemicals.
