wood treated with wood preservatives is treated with creosote (2). The tendency of creosote to exude or ‘bleed” from some treated commodities, producing an oily or tar-like (“crud”) covered surface (12), can cause handling problems and has increased public con-cern about its effect on the environment.
Creosote bleeding from the surfaces of. This chemical has performed well in almost every environment except in areas where marine borer hazards are high because of attack by Limnoria tripunctata (this species of borer is capable of attacking creosoted wood in warmer marine saltwaters).
Creosote provides the added advantages of protecting the wood from the effects of weathering and. Creosote treated wood has been a building material of choice for many years where protection against decay and rot is required.
It is effective against marine borers. Before the development of newer products, creosote treated wood, which was first patented in. "There are three broad categories of preservative treatments for wood currently in use: creosote, oilborne chemicals, and waterborne chemicals.
Creosote is a highly complex mixture of chemicals distilled from coal tar, which is a by-product of producing coke from bituminnous coal in coking ovens. Creosote is essentially an oil-based compound. Wood creosote, coal tar creosote, coal tar, coal tar pitch, and coal tar pitch volatiles differ from each other with respect to their composition.
Wood creosotes are derived from beechwood (Fagus, referred to herein as beechwood creosote) and the resin from leaves of the creosote bush (Larrea, referred to herein as creosote bush resin).File Size: 2MB. Creosote is the name used for a variety of products: wood creosote, coal tar creosote, coal tar, coal tar pitch, and coal tar pitch volatiles.

Contact a FELA lawyer to learn more about your legal rights. Some of the compounds in coal-tar creosote that have the most serious health effects are polycyclic aromatic hydrocarbons (PAHs).
Creosote is typically composed of about 85% PAHs and 2–17% phenolic compounds (Bedient et al., ).Burchiel and Luster () stated that PAHs are known to cause diseases in organ systems during organ and lymphoid cell development.

Since creosote buildup restricts flow, which slows the smoke on its way out, allowing more time for it to cool and more creosote to condense, restricting the flow further, a clean, properly maintained chimney with a good draught is a prerequisite of safe wood-burning.
Side effects include kidney or liver disease, convulsions, chemical burns, cancer - and in some instances scrotum cancer.
