What happens if you breathe creosote?
According to the National Institutes of Health, breathing creosote fumes can lead to irritation of the respiratory tract, which can cause coughing and shortness of breath. People exposed to creosote emissions also have experienced skin irritations that include redness, burning sensations, and rashes.
Will a hot fire remove creosote?
One method to loosen crusty or tarry creosote so it flakes off and falls down into the firebox or fireplace is to burn aluminum cans in a very hot fire. While this method works, it does not clean the chimney of creosote completely, and chimney brush cleaning is still necessary.
How long does it take for creosote to break down?
However, it may take from months to years for creosote to completely break down. Creosote may pose a risk to groundwater, particularly at sites where there is highly contami- nated soil and a shallow source of water (see Figure 3).

When was creosote first used?
The use of coal-tar creosote on a commercial scale began in 1838 , when a patent covering the use of creosote oil to treat timber was taken out by inventor John Bethell. The "Bethell process"—or as it later became known, the full-cell process —involves placing wood to be treated in a sealed chamber and applying a vacuum to remove air and moisture from wood "cells". The wood is then pressure-treated to impregnate it with creosote or other preservative chemicals, after which vacuum is reapplied to separate the excess treatment chemicals from the timber. Alongside the zinc chloride-based "Burnett process", use of creosoted wood prepared by the Bethell process became a principal way of preserving railway timbers (most notably railway sleepers) to increase the lifespan of the timbers, and avoiding having to regularly replace them.
Why is the history of creosote important?
This history is important, because it traces the origin of these different materials used during the 19th and early 20th centuries. Furthermore, it must be considered that these other types of creosotes – lignite-tar, wood-tar, water-gas-tar, etc. – are not currently being manufactured and have either been replaced with more economical materials, or replaced by products that are more efficacious or safer.
How to make wood tar creosote?
The creosote can be obtained by distilling the wood tar and treating the fraction heavier than water with a sodium hydroxide solution. The alkaline solution is then separated from the insoluble oily layer, boiled in contact with air to reduce impurities, and decomposed by diluted sulphuric acid. This produces a crude creosote, which is purified by re-solution in alkali, re-precipitation with acid, then redistilled with the fraction passing over between 200° and 225° constituting the purified creosote.
How does creosote affect marine pilings?
Even though creosote is pressurized into the wood, the release of the chemical - and resulting marine pollution - occurs due to many different events: During the lifetime of the marine piling, weathering occurs from tides and water flow which slowly opens the oily outer coating and exposes the smaller internal pores to more water flow. Frequent weathering occurs daily, but more severe weather, such as hurricanes, can cause damage or loosening of the wooden pilings. Many pilings are either broken into pieces from debris, or are completely washed away during these storms. When the pilings are washed away, they come to settle on the bottom of the body of water where they reside, and then they secrete chemicals into the water slowly over a long period of time. This long term secretion is not normally noticed because the piling is submerged beneath the surface hidden from sight.
What is creosote used for?
They are typically used as preservatives or antiseptics. Some creosote types were used historically as a treatment for components of seagoing and outdoor wood structures to prevent rot (e.g., bridgework and railroad ties, see image).
Where was creosote transported?
Wood railroad ties before (right) and after (left) impregnation with creosote, being transported by railcar at a facility of the Santa Fe Railroad, in Albuquerque, New Mexico, in March 1943. This U.S. wartime governmental photo reports that "The steaming black ties in the [left ...
Which antiseptic is the strongest?
All of these have antiseptic properties. The tar acids are the strongest antiseptics but have the highest degree of solubility in water and are the most volatile; so, like with wood-tar creosote, phenols are not the most valued component, as by themselves they would lend to being poor preservatives.
What does creosote smell like?
Creosote, which smells much like mothballs, is a chemical concoction that has been widely used as a preservative to treat pier pilings, railroad ties, utility poles, and other wood that sometimes winds up in the construction of a home or office building.

Overview
Creosote is a category of carbonaceous chemicals formed by the distillation of various tars and pyrolysis of plant-derived material, such as wood or fossil fuel. They are typically used as preservatives or antiseptics.
Some creosote types were used historically as a treatment for components of seagoing and outdoor wood structures to prevent rot (e.g., bridgework and railr…
Creosote oils
The term creosote has a broad range of definitions depending on the origin of the coal tar oil and end-use of the material.
With respect to wood preservatives, the United States Environmental Protection Agency (EPA) considers the term creosote to mean a pesticide for use as a wood preservative meeting the American Wood Protection Association (AWPA) Stan…
Health effects
According to the Agency for Toxic Substances and Disease Registry (ATSDR), eating food or drinking water contaminated with high levels of coal-tar creosote may cause a burning in the mouth and throat, and stomach pains. ATSDR also states that brief direct contact with large amounts of coal-tar creosote may result in a rash or severe irritation of the skin, chemical burns of the surfaces of the eyes, convulsions and mental confusion, kidney or liver problems, unconscious…
Build-up in chimneys
Burning wood and fossil fuels in the absence of adequate airflow (such as in an enclosed furnace or stove), causes incomplete combustion of the oils in the wood, which are off-gassed as volatiles in the smoke. As the smoke rises through the chimney it cools, causing water, carbon, and volatiles to condense on the interior surfaces of the chimney flue. The black oily residue that builds up is referred to as creosote, which is similar in composition to the commercial products …
Release into environment

Chemical reactions with sediment and organisms
Once the soluble compounds from the creosote preservative leach into the water, the compounds begin reacting with the external environment or are consumed by organisms. The reactions vary depending on the concentration of each compound that is released from the creosote, but major reactions are outlined below:
Alkylation occurs when a molecule replaces a hydrogen atom with an alkyl group that generally c…
Environmental hazards
In aquatic sediments, several reactions can transform the chemicals released by the creosote preservatives into more dangerous chemicals. Most creosote preservative compounds have hazards associated with them before they are transformed. Cresol (m-, p-, and o-), phenol, guaiacol, and xylenol (1,3,4- and 1,3,5-) all are acute aquatic hazards prior to going through chemical reactions with the sediments. Alkylation reactions allows for the compounds to transition into m…
