What is a nonpressurized container?

A nonpressurized container is a type of storage vessel that does not maintain internal pressure above atmospheric levels. These containers are designed to hold liquids, gases, or solids without the risk of explosion or leakage due to pressure buildup. Common examples include open tanks, buckets, and certain types of storage drums. They are typically used in applications where pressure containment is not necessary or where safety is a primary concern.
