Justification for use of mirex in termite control
1988 - IRG/WP 1346
In August 1987, organochlorines were withdrawn in North America from use in termite control. This has left the industry and the community with reduced options in long term protection of wood and wood products. A case is presented to justify the use of the slow-acting stomach termiticide, mirex, under special permit, for use only in the bait-block method of termite control. This method, while not a...

Health hazards and environmental aspects when using Cu-HDO-containing wood preservatives in vacuum pressure plants
1993 - IRG/WP 93-50001-11
Apart from the biological efficacy of wood preservatives, the health and environmental aspects concerning the utilisation of wood preservatives, the use of treated timber and the disposal of impregnated wood are of high significance today. Therefore, information on a possible aerial concentration of wood preservatives, on the mobility of active substances in soil leached from treated timber in ser...

The dip diffusion treatment of tropical building timbers in Papua New Guinea
1972 - IRG/WP 310
In Papua New Guinea a dip diffusion process using a multi salt preservative developed by C.S.I.R.0. has been in commercial use for 8 years. Over 200 million super feet (236,000 m³ ) of timber has been treated during this period and current rate of treatment is 34 million super feet (80,400 m³ ) of timber per year in 70 licenced treatment plants. The process has been found to be simple to apply, ...

Leaching from CCA-impregnated wood to food, drinking-water and silage
1987 - IRG/WP 3433
During the last years The Norwegian Institute of Wood Technology (NIWT) has analysed different foodstuff for contamination by copper, chrome and arsenic from CCA-impregnated wood. There has been some interest for using CCA-impregnated wood in contact with food and drinking-water. Before giving their permission the Norwegian Health Authorities want results from experiments. NIWT therefore started t...

Environmental aspects of wood preservation
1987 - IRG/WP 3406
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 sa...

CCA wood preservative: Trust with destiny
2019 - IRG/WP 19-30731
This paper traces the history of Copper-Chrome-Arsenic (CCA) and its current status in India and worldwide. CCA was invented as ASCU at the Forest Research Institute, Dehra Dun in 1933 by Dr. Sonti Kamesam. Although its efficacy was doubted by the British colonial rulers resulting in several hiccups at home, the patent rights were purchased by US Bell Telephone Co. and it was adopted by the US woo...

Proposed methodology for the assessment of safety indexes
1990 - IRG/WP 3562
Safety Indexes (SI)s are developped on the same concept as Efficacy Indexes (EI)s: EIs are retentions of wood preservatives (percentages of the critical values "efficacy") which are presumed efficient for a given biological class of risk. In the same way, SIs are retentions of wood preservatives (percentages of the critical values "safety") which are taken as acceptable for human health and the ge...

Health aspects concerning the use of bifluorides in wood
1981 - IRG/WP 3173
An attempt has been made to find a correlation between the quantities F¯ and HF present among other ions in an 'Improsol' solution consisting of NH4F.HF and KF.HF, the quantity absorbed by the wood from this after immersion and the toxicological effects of this treated wood when it is used in rooms destined for the residence of people or animals or for the storage of foodstuffs....

Radical changes in the requirements for more safe pressure impregnation in the Nordic countries in 1988
1990 - IRG/WP 3581
After introduction of quality control schemes and standards in the Nordic countries during the seventies, the first radical change of the standards and practice of work took place after pressure from the labor unions and authorities in 1988 and 1989 in Denmark and in Sweden. A new class of preservation with less retention for out of ground contact use was introduced, fixation times were prolonged ...

PCP dioxins found to pose health risks
1980 - IRG/WP 3152
Following wide debate on the hazards of TCDD, US scientists are now expressing concern about the possible health hazards of low-level exposure to other dioxins, particularly those in the widely-used wood preservative pentachlorophenol (PCP)....

Exposure monitoring of creosote vapors
1989 - IRG/WP 3511
Creosote oils contain hundreds of compounds. During impregnation and handling of treated wood the main component in the vapors released in air is naphthalene. Other main components are alkyl naphthalenes, indene, phenol and its methyl derivatives, benzothiophene, diphenyl, acenaphthalene and fluorene. In the measurement of creosote vapors, naphthalene can be used as an indicator agent. One of the ...

Chlorodioxins in pentachlorophenol
1975 - IRG/WP 346 E
At the 6th meeting of the IRG/WP plenary group held on 20 June, 1974, in Vienna, Mr Richardson expressed some concern about dioxins which might be contained as impurities in pentachlorophenol and in sodium pentachlorophenoxide or which might be formed during the combustion of treated wood. He mentioned the malformations that have been noted in Vietnam due to the teratogenic action of the 2, 3, 7, ...

Framework document for an international code of good practices for wood preservation and wood protection (anti-sapstain) facilities
1992 - IRG/WP 92-3683
At the Kyoto meeting, the Health & Safety committee agreed to form a task force to prepare a global plan for writing a code of good practices (Code) for wood protection and preservation facilities (Doc. No. IRG/WP/3681). The Canadian document had been presented to the IRG group earlier (Doc. No. IRG/WP/3447) and similar documents were solicited from other countries for preparing a framework do...

Proposal for further work on environmental questions
1988 - IRG/WP 3494
Although very much is known about the environmental and health and safety aspects on various wood preservatives and treated wood knowledge is still lacking on some important issues. Some examples are: - The fate of wood preservatives in the environment, eg by leaching from treated wood and contaminated soil; - How big is the "problem" of pollution, etc from the wood preserving industry in comparis...

Safety clearance of wood preservatives in United Kingdom
1977 - IRG/WP 398
In the United Kingdom the principal route of control of pesticides is through the Pesticides Safety Precautions Scheme (PSPS) which is a non-statutory scheme agreed between government ministries and departments (referred to as "Departments") and associations representing the pesticide industries. The scheme formally began in 1957 covering those pesticides and related substances used in agriculture...
