Water Quality District - Hazardous Waste
Formaldehyde/Formalin
What is it?
Formaldehyde (also known as Methanal) is a colorless gas, and is used in the manufacture of some household products and building materials. Formalin is a liquid solution of formaldehyde and water, with methanol added as a stabilizer. It is used as a disinfectant and preservative for biological specimens, and is sometimes referred to as formaldehyde, although this is not technically correct.
What Makes it Hazardous?
Exposure to Formaldehyde (and Formalin) can irritate skin, nose, throat, eyes and may increase the risk of cancer. Formaldehyde can off-gas from some household products and building materials. Some laboratory employees or students may be exposed to Formalin.
Safety Tips
- Allow new building materials to air out before using area.
- Use formaldehyde-containing lab products only with adequate ventilation.
- Choose products that contain lower levels of formaldehyde, or less-toxic alternatives.
Disposal Options
Dispose:
- Most formaldehyde-containing building materials and household products can be disposed of in a landfill. Contact BFI (728-9572) if you are unsure.
- Formalin or other liquids containing formaldehyde can be disposed of at Haz Waste Days, in September.
