Information from the COIPM Wood Group
1986 - IRG/WP 4130
The Chairman outlined the progress of the co-operative work "testing the resistance to marine borers of heat shrinkable polyolefin sheathings and of wood treated by vacuum/pressure with polymers (polystyrene)". The first part of the work has been started: the samples of wood wrapped with shrinkable polyolefin sheathings have been prepared and sent to the stations participating. The second part of ...

Proposals for a field experiment to determine the performance of preservative treated hardwoods with particular reference to soft rot
1975 - IRG/WP 342
It is proposed to treat a series of hardwood stakes in the UK and install them in different sites around the world. The stakes will include 3 reference species common to every site and 2 locally selected species. The hazard of termites should be avoided in order to limit the study to action of micro-organisms....

Canadian code of good practices - Recommendations for design and operation of wood preservation facilities
1990 - IRG/WP 3582
The rationale and procedures for the development of a set of recommendations for design and operation of wood preservation facilities in Canada are discussed. Multi stake holders involvement in problem identification, problem assessment, state of the art knowledge database, implementation and periodic assessment procedures are important considerations for the successful development of a Code of Go...

A comparative study of CCA type C and B treated poles in service
1993 - IRG/WP 93-50001-05
CCA K33 type B and C treated utility poles, 9 pieces of each treatment type, were analyzed for preservative retention after 11 years in use. Borings were taking 1 m above and 0.3 m below the ground line. Also total amount of copper, chromium and arsenic was determined in soil surrounding the poles. The solubility of these active components in soil was monitored by using different leaching procedur...

The shower test method. A leaching test for assessing preservative losses from treated timber under simulated open storage conditions
1993 - IRG/WP 93-50001-04
In the late 1980's against the background of increasing environmental concern a laboratory based accelerated leaching test method for assessing preservative losses-from stored, treated timber was developed by the Dutch organisation for applied Scientific Research (TNO). This test method quantifies the amount of specific preservative components which leach from treated timber under simulat...

Issues Facing Wood Preservation in New Zealand Today
2003 - IRG/WP 03-30326
In New Zealand, the three major issues facing the wood preservation industry today are:
Extension of use of LOSP preservatives, chiefly tributyltin naphthenate, for treatment of products in Hazard Class H3 exposed to the weather for which LOSP have not been traditionally used. Concerns have been expressed about the long-term durability of such products.
Restrictions on the use of CCA preservativ...

An environmental assessment of timber treatment plants in Australia
1999 - IRG/WP 99-50124
Australian Standard AS 2843 Timber Preservation Plant Safety Code, sets the specifications for the design and operation of timber treatment plants in Australia. The Timber Preservers' Association of Australia has carried out an environmental survey of timber treatment plants throughout Australia using the operational checklist provided in Appendix C of Part 2 of the Standard. Third party ...

Health and safety aspects of the use of wood preservatives in Sweden
1977 - IRG/WP 396
The Act on products Hazardous to Health and to the Environment (Swedish Code of Statutes SFS 1973:329) came into force on 1st July 1973. The Act cancelled and superseded the Poison Act, the Pesticides Act and the PCB Act from 1962, 1962 and 1971 respectively. Regulations for the implementation of the Act are contained in the Ordinance on Products Hazardous to Health and to the Environment (SFS 197...

Soft-rot problems with treated hardwoods: A paper for discussion and establishment of a programme of work
1974 - IRG/WP 331
At the 5th meeting of IRG in Lahti (June 1973) it was decided that an ad hoc group should be formed to study these problems. It was decided that it's activity could be usefully directed in two main areas; a) in the encouragement and direction of existing research in this field, and b) in the organising of a collaborative field trial involving interested parties using locally important har...

Determination of fixation properties by bioassays - A proposal for the assessment of safety indexes in wood protection
1990 - IRG/WP 3566
In the determination of environmental effects of chemicals tests with fishes, daphnia and algae have proved to be practicable. With respect to wood protection such bioassays are suitable to control effects of treated timber against aquatic organisms. By using the fish-acute-toxicity-test the development of a laboratory test method is described for the checking of the fixation rate of a copper-chro...

Environmental situation on wood preservation industries in Bangladesh
2000 - IRG/WP 00-50148
The hazard that wood preservative chemicals pose to people and the environment is serious. The lack of information, legislation and awareness create an unfavorable situation on wood preservation industries. In this regard, three wood preservation industries have been visited to collect the information about pollution. It was observed that different steps have been taken to minimize the contaminati...

Kiln drying of CCA-treated wood - Some safety and environmental considerations
1987 - IRG/WP 3443
Vapours and condensate from a condenser kiln in which CCA-treated wood was being dried have been collected and analysed. The concentrations of arsenic, copper and chromium found in the vapours from the drying process were well below Swedish threshold limit values. The contents of arsenic and chromium were also low in the condensate, although the copper content was fairly high. The latter result wa...
