Creosote and Health Hazards

Creosote, according to the federal Environmental Protection Agency, refers to combinations of chemicals found in such products as wood and coal. It's commonly used to preserve wood. Creosote can pose health hazards to animals, the environment and people. Regulations are in place to control its release during manufacturing.

  1. In the Environment

    • Creosote can get into the environment in many ways. When coal is treated at extremely high temperatures to produce natural gas, coal tar is one of the byproducts. Creosote in the coal tar can leak into water sources from hazardous waste sites. It can also be found in home chimneys in which coal tar has built up. When it gets into a water source or soil, creosote can be a danger to those who come into contact with it.

    Coal Tar Creosote

    • Those exposed to coal tar creosote can develop lower tolerance for the sun's rays.

      Individuals who breathe in coal tar creosote or get it on their skin can suffer health problems. Outward effects can include burning of the eyes, rash and irritated skin. Exposure can also damage the liver and kidneys. If creosote is present in high enough amounts in a person's body, it can cause death. Those exposed to it for long periods can develop a decreased tolerance for the sun, reddened skin and blisters.

    Exposure

    • Creosote can enter a child's system if he puts his hands into his mouth directly after touching treated wood containing creosote. Workers in plants where wood is treated can breathe in dust or fumes from the process, or absorb creosote through the skin. Animals and plants can be exposed through water and soil that have been contaminated; the creosote is then passed on to people who consume them for food.

    Treated Wood

    • Animals should be kept away from wood treated with creosote.

      Wood that has been treated with creosote can pose hazards as well. The EPA advises that people avoid too much contact with creosote-treated wood. Gloves are recommended when handling it. It can also pose a threat to animals, so they should be kept away from it.
