What do large, above-ground, horizontal storage tanks typically hold?

Large, above-ground, horizontal storage tanks are primarily designed to store flammable or combustible liquids. This type of storage is common in various industries, including oil and gas, chemicals, and agriculture. The design of these tanks allows for efficient storage of large volumes of liquid products that may pose fire hazards due to their flammable nature.

These tanks are often constructed with safety features to minimize the risk of leaks or spills, which could lead to significant fire and environmental hazards. Additionally, regulations regarding the storage of flammable substances dictate proper construction materials and safety measures to mitigate risks.

In contrast, solid waste materials and compressed gases are typically stored in different types of containers specific to those materials, and water for firefighting is usually stored in dedicated tanks or systems that prevent contamination. Understanding the primary use of these storage tanks is crucial for fire safety and prevention practices in the field.
