  Safety Issues

Treatments

Available treatments for pallet and packaging timber include high temperature or gas fumigation for pests, kiln drying to remove moisture, cool air for drying, fire resistant intumescent pressure and brush treatments, preservative solutions against decay where food is not involved, painting or staining for identification, cleaning solutions and wax emulsion protection against surface moisture gain and stain (typical results of transparent wax emulsions on softwood specimens are illustrated here).

Europe, North America and increasingly other countries all now have to take account of local or destination environmental regulations which now limit or exclude the use of some treatments for certain end uses, an example is copper chrome arsenate (CCA) which has been largely replaced in Europe and North America with a formula based on pressure treatment with one of the new copper quaternary compounds if timber is used in damp conditions.

When food, drink or pharmaceutical payloads are carried, pallet suppliers and users need to be wary of what may have been used and what is permitted. We have a range of Datasheets on these matters within this site (or due) and explain some of these treatments and their limitations. Members should call us if a subject they need is not listed and cannot be found using QUICK SEARCH.

A PalletLink database is kept of commercial outlets and suppliers of these treatments in the UK and Europe but is not yet part of this website but members are welcome to e-mail us for suppliers needed.
