What is the containment requirement for hoses with a diameter greater than 12 inches?

The containment requirement for hoses with a diameter greater than 12 inches is four barrels. This specification is established to ensure effective management of potential spills or leaks from larger diameter hoses, which can discharge a larger volume of fluid. The containment system must be sufficient to capture any spill that may occur, minimizing environmental impact and enhancing safety measures.

The requirement for four barrels provides a buffer to accommodate the maximum possible discharge, ensuring that even in the event of a failure, containment measures are in place to prevent the fluid from escaping into the surrounding environment. This standard reflects best practices in spill prevention and response, particularly for hoses that convey hazardous materials.

It's important to understand that the capacity of containment systems is vital for maintaining compliance with regulations concerning safety and environmental protection, which is why a specific number like four barrels is mandated for hoses of this size.
