Similar to UC4 timber standards, pressure treated creosote goes through the same process. Only selected suitable redwoods are used and the timber is dried to a moisture content of less than 28% & then treated with tar coal creosote.
Creosote Guidance
This timber is treated with 100% Coal Tar Creosote. Avoid contact with skin. Handle with gloves. Wear a dust mask and eye protection when sawing or machining. Dispose of off-cuts, sawdust etc safely. Waste wood may be disposed of by burning subject to any local rules on burning in the open or via your local waste disposal facility. Creosoted timber should not be used where there is risk of frequent (i.e. often-occurring, habitual or constant) skin contact nor where it may come into contact with or contaminate animal or human foodstuffs. In particular it should not be used inside buildings, to make toys, in playgrounds, for garden furniture or picnic tables.
