I am planning to install a polyethylene storage tank for a chemical that is classified as an oxidizing liquid but not flammable. Nitrogen blanketing is not required for this application. For normal breathing (in and out), I intend to use a gooseneck vent in accordance with API 2000.
My question is: Do I need to consider emergency venting for fire scenarios?
Given that the tank is made of HDPE, I assume that in the event of a fire, the tank would melt rather than build internal pressure. Therefore, I am leaning toward not including an emergency vent. However, I want to ensure this approach aligns with best practices and safety standards.
Any insights or references to applicable codes or standards would be greatly appreciated.
