Understanding Creosote In Wood Treatment

How Is It Made?

Creosote is produced by heating coal in a low-oxygen environment. The vapours released are condensed into coal tar, which is then further distilled to extract creosote. This substance contains a complex mixture of hundreds of chemicals, including many polycyclic aromatic hydrocarbons (PAHs), some of which are known to be toxic and carcinogenic.

What Does Creosote Do?

Creosote is used to preserve timber, making it resistant to decay, insects, and fungi. It’s commonly used on:
Railway sleepers
Utility poles

It provides long-lasting protection for wood used in harsh outdoor environments.

Health and Environmental Risks

Health risks:
Skin irritation and chemical burns
Respiratory problems from vapour inhalation
Carcinogenic

Environmental risks:
Leaches into soil and groundwater
Harmful to aquatic life
Persistent and bioaccumulative in the ecosystem

The Irish Ban (2023)

While the EU initially restricted creosote use in 2003, Ireland introduced its own stronger domestic ban in April 2023 under the Creosote (Prohibition on Use and Marketing) Regulations 2023.

This Regulation:
Prohibits the sale and use of creosote except under strict EPA licence
Bans its use anywhere with potential human or animal contact (gardens, farms, etc.)
Requires disposal and handling by authorised professionals only.

ScanPole – Ireland’s Only Authorised User

ScanPole, formerly PDM, is the only facility in Ireland with an EPA licence to continue using creosote for industrial timber treatment. Located in Kill, Co. Kildare, it has faced strong community opposition due to:
Persistent chemical odours impacting residential areas
Health complaints
Environmental concerns
