Environmental and Health Hazards

Wood preservatives and pressure-treated lumber may contain toxic substances. Instructions must be read carefully. Pressure-treated lumber should never be burned. Gloves and protective clothing and disposal of excess material and debris according to regulations is mandatory. For folks in the Seattle area, the Seattle/King County Health Department can answer any specific questions.

Similar Household Hazards Information Line services are provided by local agencies in most parts of the country.
