Why is RPB installed on the tank bottom?
The new concept may also include the use of a conductive (clay) liner to be installed over the old tank bottom as a release prevention barrier (RPB), allowing CP current flow through the conductive liner, while protecting the environment. A conductive RPB may or may not be used in combination with the new method.
Is asphalt impregnated board flammable?
ignite or form explosive mixture with air. Wood dust or asphalt may be irritating to eyes, skin or respiratory system. If heated beyond 200°F, or if the product catches fire, product will emit toxic fumes and/or gases. Avoid inhaling asphalt fumes and/or gases.
Are asphalt boards waterproof?
A finished board can be left plain or it can be impregnated with asphalt, which makes it more moisture-resistant. The fiberboard can also be coated with asphalt, which not only provides additional resistance to moisture, but it also improves its bonding characteristics.
What is a release prevention barrier?
A liquid-containment barrier installed underneath an aboveground storage tank that is sufficiently impervious to the liquid being stored.
What is a double bottom tank?
