welshphil:
We used to tip nitric acid on the ind estate by LPG in batley,next to the A62.We were told to vent through the storage tank,(“just let it blow,driver”).Nitric fumes across the main road ,up in the atmosphere,aircraft rivets corroding as they flew over!!!What was the firm called,any idea,Chris?
Sorry Phil,I know where LPG was but don’t know the firm where you vented 
How many times have I heard the words “Lerrit go drive,bags of room” and it’s come over the top.H and S,what H and S
