Does a 20-cubic-meter horizontal atmospheric-pressure storage tank filled with 40% dilute nitric acid need a breathing valve?

Atmospheric pressure storage tanks need to be equipped with breather valves.

How is atmospheric pressure controlled? Don’t all those under pressure require a breathing valve? This isn’t just daydreaming

By the way, if a breathing valve is needed, how should it be selected? Most of the information available relates to breathing valves for oils; so how should one choose a breathing valve for dilute nitric acid?
