Which of the following is not a type of storage found at a fixed facility?

Manufacturing is not categorized as a type of storage found at a fixed facility. Instead, it refers to the process of producing goods and involves the transformation of raw materials into finished products.

In contrast, warehouse storage, bunker storage, and tank storage are all specific types of storage designed to hold materials safely and securely. Warehouse storage is typically used for a wide range of goods and provides an organized system for inventory management. Bunker storage is used for materials that require heavy security or environmental protection, often found in contexts such as munitions or hazardous materials. Tank storage is specifically designed for liquids, often hazardous substances, to ensure safe containment and minimize risks to the surrounding environment. Each of these storage types is focused on the safety, security, and management of stored materials, making manufacturing distinct and not fitting into this category.
