Thanks for the help.
The Lines are for liquid chlorine from a 1 tonne drum through a vapouriser and then chlorine gas supply. Think we have got everything we need in place but just need some direction on how to present it to the HSE.
I am required to do a fitness for service assessment on some chlorine lines and assossiated equipment. I have never done one before or even seen one. Any one give me some pointers on what I need to be putting in it and what the HSE will be expecting?
