MJCronin,
I agree that the tanks will be best placed outdoors in a contained area, however the client wants to know what will be required if placed indoors. the building is a small, unoccupied, process station. I do not have experience in locating acid and caustic tanks and their requirements. What are some reasons I could list justifying locating the tanks outdoors? What would the outdoor requirements be for the tank storage? If you have some thoughts, I would appreciate it.
