What is Creosote?

Creosote is a dark brown or black, oily liquid that has a strong, smoky odor. It is a byproduct of burning wood, coal, or other organic materials. Creosote is commonly found in the chimney of a wood-burning fireplace or stove and can also be used as a wood preservative.

When wood is burned, the smoke that rises up the chimney cools down and condenses on the walls of the chimney. Over time, this buildup of condensed smoke forms a sticky, tar-like substance called creosote. Creosote can be dangerous because it is highly flammable and can cause chimney fires if it is not removed regularly.

Creosote can also be dangerous if it is used as a wood preservative. According to the US Environmental Protection Agency (EPA), creosote has been used as a wood preservative since the mid-1800s. However, it poses cancer and non-cancer health risks of concern to workers in wood treatment facilities. The health risks include respiratory illnesses, skin damage, and eye damage.

It is important to note that creosote-treated wood is not recommended for use in buildings occupied by humans due to the potential health risks. The U.S. Agency for Toxic Substances & Disease Registry (ATSDR) lists several potential dangers of using creosote-treated wood, including respiratory illnesses, skin damage, and eye damage.

In summary, creosote is a byproduct of burning wood that can be dangerous if it is not removed regularly from chimneys or if it is used as a wood preservative. It is important to take precautions to prevent the buildup of creosote in chimneys and to avoid using creosote-treated wood in buildings occupied by humans.
