To clarify - creosote is banned for use by the general public - UK legislation details here
The danger arises from skin contact which has been found to increase the risk of developing cancer.
The reason it is permitted for use in professional/industrial situations is that regulations can be applied and training can be given and penalties applied if these are not adhered to.
Any business supplying creosote to a member of the general public is in breach of the regulations and liable to be prosecuted.
