Health and safety aspects of the use of wood preservatives. Preliminary evaluation of the answers to the IRG-Questionnaire on the state of pollution control in the field of wood preservation
1974 - IRG/WP 56
This preliminary evaluation of the answers to the IRG/WP-Questionnaire only gives a general survey on those questionnaires, which the author received until June 13, 1974. Details, such as correlations between importance of wood preservation and pollution control, could not be considered due to lack of time. For the same reason it was not possible so far, to evaluate the additional remarks given in...

Risk assessment and the approval of wood preservatives in the United Kingdom
1995 - IRG/WP 95-50040-23
An approval system operates in the United Kingdom (UK) for the regulation of wood preservatives. The regulatory authority uses a risk assessment approach to evaluate how far the potential for harm to people and the environment from wood preservatives is likely to be realised in practise, and hence the controls required for products to be, used safely. The evaluation for approval purposes also take...

Current models used by the European Health Authorities to evaluate the volatilization of active ingredients from treated wood used inside dwellings. A case study: Volatilization of azaconazole and propiconazole from treated wood
1990 - IRG/WP 3565
The use of wood preservatives inside houses may result in measurable aerial concentrations of active ingredients. These airborne contaminants may be inhaled by the inhabitants over periods lasting from a couple of days to several months. To assess the potential health hazard of preservative residues in the air, various risk-assessment models have been worked out. Three schemes, currently used by t...

Wood preservation in Kenya
2000 - IRG/WP 00-40191
Current research on wood preservation in Kenya is mainly on the development of biological control of wood-destroying termite species, using mycoinsecticides. The major research institutions include the Kenya Agricultural Research Institute (KARI), Kenya Forestry Research Institute (KEFRI), Moi University and the International Centre for Insect Physiology (ICIPE). Training institutions include Fore...

Evaluation of the fire retardant efficacy and leach resistance of an amino resin fire retardant - Preliminary report
1983 - IRG/WP 3260
The Early Fire Hazard Indices of untreated Pinus radiata were determined by testing to Australian Standard 1530, Part 3 - 1976. Differences in the performance of heartwood and sapwood were noted, with heartwood samples giving higher Ignitability, Heat Evolved and Spread of Flame indices. The treatability of Pinus radiata with Pyrogard H was assessed, and backsawn sapwood treated more effectively t...

Chapter 6 - Preservatives of bamboo
2007 - IRG/WP 07-10635-06
Almost all currently available oil-borne, water-borne and
compound types of preservatives suitable for the
preservation of bamboo or wood have been described along
with their classifications, applications, formulations, merits
and demerits, history of invention or discovery and
development. The preservatives suitable for wood are also
considered suitable for bamboo....

Bending Properties of FRT OSB
2012 - IRG/WP 12-40600
Fire retardant treated (FRT) oriented strandboard (OSB) and plywood of different widths were tested in static bending to determine width effects. Results were consistent with previous width effect studies and showed that increasing specimen width results in a decrease in sample MOR properties among all the sample groups tested in this study. Increasing sample width for OSB samples leads to more ...

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...

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...

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...

Serviceability modeling-Predicting and extending the useful service life of FRT-plywood roof sheathing
2000 - IRG/WP 00-20210
One of the most, if not the most, efficient methods of extending our existing forest resource is to prolong the service life of wood currently in-service by using those existing structures to meet our future needs (Hamilton and Winandy 1998). It is currently estimated that over 7 x 109 m3 (3 trillion bd. ft) of wood is currently in service within the United States of America (PATH 1999). Research ...

A status report on code of good practices
1991 - IRG/WP 3679
Code of Good Practices - Anti Sapstain documents, presented to IRG meetings in the past, are the basic documents for health and safety of the workers and the environment in Canada. The BC Ministry of Environnment has now issued regulations in the area of effluent discharge. While Pentachlorophenols (PCP) are not used by the industry, the documents are still used as a guideline document for the oth...

Proposal for further work on fixation of CCA-preservatives in wood
1988 - IRG/WP 3493
Many studies on the fixation and fixation-mechanism of CCA-preservatives in lignocellulose materials have been published but few on the practical consequences of this knowledge. For the wood preserving industry and the user of treated wood it is important to know what is meant by the word fixation, when fixation is complete and how fixation can be recorded in an easy way according to a non-destruc...

Safe application of copper-chrome-arsenate preservatives
1975 - IRG/WP 377
All wood preservatives contain biologically active substances and must, by design, be in some measure toxic to man. There is nothing fundamentally difficult, however, about using a wood preservative with complete safety. It depends on knowing the risks to health and/or the environment, which the preservative may present, and planning application accordingly. In this paper we examine these and othe...

The new National Directive on wood preservation in the Netherlands
1998 - IRG/WP 98-50101-03
In the Netherlands the major part of treated timber is sold under the KOMO-certificate. The National Directive for vacuum pressure treated timber on which certification is based, is currently being revised. The new National Directive will contain a code of good practice including maximum leaching figures. It incorporates quality requirements for treated timber, existing legislative requirements an...
