Diesel Tank Bund: Key Differences from Other Bund Types
Material Requirements
Diesel bunds must be constructed from materials resistant to diesel's chemical properties. Diesel can corrode certain materials over time, so bunds for diesel tanks often use concrete, steel-reinforced concrete, or specific chemical-resistant linings. In contrast, bunds for non-corrosive substances like water may not have such strict material demands.
Capacity Specifications
Diesel bunds are typically designed to hold 100% of the volume of the largest tank within the bunded area in case of a complete rupture. This is due to diesel's flammability and environmental harm if spilled. Other bunds, such as those for less hazardous materials, may have lower capacity requirements, perhaps only designed to handle minor spills or leaks.
Safety & Environmental Features
- Diesel is both a fire hazard and an environmental pollutant
- Require fire-resistant materials and proper ventilation
- Need strict drainage systems with oil-water separators
- Must prevent accumulation of explosive vapors
- Designed to ensure leaked diesel is properly contained
Overall, these differences reflect the unique risks associated with storing and handling diesel compared to less hazardous substances. The specialized design of diesel bunds addresses both safety concerns and environmental protection requirements.
