The protection method depends on the tank design<br \/>\n      basis, operating conditions, venting arrangement, credible vacuum-producing scenarios, and<br \/>\n      applicable project requirements.

Flow-path components can introduce resistance, so the installed venting path should be<br \/>\n      evaluated as a system.
