Environmental aspects of wood preservation

IRG/WP 3406

H Greaves

The preservation industry employs a wide range of chemicals and processes to provide timber commodities capable of resisting biodeterioration and degradation. The public often perceives the chemicals as health hazards and treatment plants as potential threats to the environment. This paper attempts to place in proper perspective the value of wood preservation. It discusses aspects of health and safety of the treatment chemicals and the treatment operations. CCAs, creosote and PCP, TBTO, copper naphthenate, boron and fluoroborates, and organochlorine insecticides are all reviewed. Where appropriate, precautions are presented for handling both treated wood and the chemicals. Guidelines for treatment plant operations are also provided. These aim at minimising the potential for pollution and at promoting worker safety. It is suggested that preservative-treated wood as opposed to the unreacted treatment chemicals - does not represent a hazard to health or the environment.
