For which systems must every component be compatible with the product stored?

The correct response highlights the necessity for compatibility of every component in a storage system, specifically tanks, piping, and all associated components, with the substance being stored. This requirement is rooted in safety and operational efficiency. Each element of the system—whether it is the tank, piping, valves, or other components—interacts directly with the product, meaning any incompatibility can lead to hazardous situations such as leaks, corrosion, or other failures that can compromise the integrity of the entire system.

For instance, if a tank designed for a certain chemical is paired with piping that is not resistant to that chemical, it may deteriorate over time, leading to potential spills and environmental hazards. Similarly, valves and fittings must match the chemical properties of the stored product to ensure effective containment and proper operation.

This emphasis on compatibility not only helps prevent safety incidents and environmental contamination but also ensures compliance with regulatory standards designed to protect public health and the environment. Therefore, compatibility throughout every component of a storage system is crucial for efficient and safe operations.
