i have not been to the pub, I used to work at a cokeing plant on the benzole yard where creosote oil was used in counter flow to the coal gas , the absorbed mixture was then heated to 130c and then low pressure steam took out the crude benzole as a mix of water and benzole which separated out. the conditions were horrendous when a pump went down and we had to run in and out of a pump room with rag to face to aid breathing when starting up the spare pump because the glands were spewing out creosote at between 110c -120c the vapours were killers.they used to tell us to put benzole in mop buckets with concentrated soap and heat it up with a steam hose to lift tar off of tiled floors , this practice only stopped in the late 80s {health and safety}. some workers would put benzole in their car tanks which made them chuck out thick black smoke, they soon understood it was bad practice, we had to shovel naptholene {exuse my incorrect spelling} out of benzole tanks when they had only been opened up to air flow for three days, anybody who knows an ex coke worker should know the conditions were worse than a pit. you could wash the coal off, but you never washed of the pungent stink of the chemicals that were just about to stop oozing out of your skin after a weeks holiday.Back to the cancer point of view I hope ive got away with it, many haven't..
