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.

Just make the gooseneck vent big enough for the hypothetical fire case, and you’ll be covered.

Hi,

Consider talking to safety bureau and/or fire department to get appropriate answer.

Why don't you share with us the name of the chemical?
