Environmental issues: Messages for the wood preservation industry
1985 - IRG/WP 3353
A review of the origins and structure of environmental legislation throughout those territories of the world where wood preservation is a major industry is given. The implications of media, industry and legislation interaction is discussed and suggestions made as to the key issues the wood preservation industry should concentrate its attentions on in the immediate future....

Danish wood preservatives approval system with special focus on assessment of the environmental risks associated with industrial wood preservatives
2001 - IRG/WP 01-50166-01
The following is a description of the procedure used by the Danish Environmental Protection Agency to assess the environmental risks associated with preservatives used in the pressure impregnation of wood. The risk assessment covers issues considered to be of significance for the environment and which are adequately documented so as to allow an assessment. Such issues are persistence and mobility ...

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)....

Ecotoxicological risks of anti-sapstain preservatives washed off from treated timber
2000 - IRG/WP 00-50144
A field method for ecotoxicity assessment of rain water wash-off from anti-sapstain treated timber was developed. In the course of this study freshly sawn timber treated with 1.5% Busan 30 L (reference preservative) and a control stack with untreated pine were exposed to weathering. The run-off water was ecotoxicologically tested with organisms from three trophic levels (Vibrio fischeri, Kirchneri...

Practical consideration in developing an international hazard class standard: The hazards and risks
1996 - IRG/WP 96-20091
This paper discusses the concept of hazards and risks in relation to the way in which the hazard class philosophy may be used for international standardization. The difference between hazard and risk is considered as a basis for a simple classification of biological hazards for timber in use based upon its service environment. The paper proposes that the moderating influences within a service envi...

Practicability of bioassays in the evaluation of environmental risks in wood protection
1996 - IRG/WP 96-50071
As an example for the proofing of the practicability of bioassays in the evaluation of environmental risks in wood protection the ecotoxicological behaviour of CCF-impregnated timber was examined. After vacuum pressure impregnation specimen from shaped pine poles were tested on ecotoxicological effects of leachable compounds using sensitive aquatic organisms like fish, Daphnia and algae as bioindi...

Assessing health risks to occupants following remedial insecticidal treatment of timber in dwellings
1998 - IRG/WP 98-50101-27
Experiments have been carried out to assess (i) the aerial concentrations of volatile wood preservative constituents, and (ii) the potential for contamination from treated surfaces, following in situ insecticidal treatment of timbers in dwellings. Using white spirit as a model for volatile constituents in the treatment of free-standing, wood-lined chambers indicated that temperature and air exchan...

Metal plate fasteners in trussed rafters treated with preservatives or flame retardants - corrosion risks
1977 - IRG/WP 3104
In designing roof trusses employing metal plate fasteners it is generally assumed that the roof will remain dry in service. Whilst this is generally true, damp conditions do arise under some circumstances, although it is not possible to quantify the extent of the risk. It is only possible, therefore, to give general recommendations which must be interpreted in the light of local experience of serv...

The use of fumigants for controlling decay of wood: a review of their efficacy and safety
1989 - IRG/WP 3525
Volatile agricultural chemicals (fumigants) such as chloropicrin (trichloronitromethane) and sodium n-methyldithiocarbamate have been used in the United States for controlling internal decay of large dimension wood products for over 20 years. This usage has been concentrated in the electric utility industry, but fumigants are increasingly applied to protect bridge timbers, marine piling, and even ...

Managing termite risks – An Australian perspective and a cautionary tale
2012 - IRG/WP 12-20482
The management of the risks of termite attack on new buildings in Australia falls to a range of agencies and is mostly achieved through controlling the process by which structures are certified as complying with the Building Code of Australia. Australian Standard AS3660 parts 1, 2 & 3 have historically been the core of this function but now the Building Codes Board's own certification scheme,...
