To ensure a secondary containment system's effectiveness, several factors must be considered. These factors include the type of stored substances and the size and capacity of the containers. These can determine what sort of material will be most effective for the particular system, as well as the scale which will be needed to provide adequate containment.
Externally, environmental conditions, regulatory requirements, and site-specific considerations such as terrain and drainage. Additionally, factors such as chemical compatibility, temperature fluctuations, and potential exposure to UV radiation should be taken into account when selecting materials for the containment system.
