A dike or containment berm is a moat-like structure built around storage tanks to contain spills, leaks, or accidental discharges. It acts as a secondary containment system designed to hold the full contents of a tank in case of failure, preventing hazardous materials from spreading into the environment.
In industrial facilities, spill control systems such as spill containment solutions and safe access equipment like work platforms are essential for maintaining safety and compliance. A properly designed dike or containment berm helps facilities meet environmental regulations while protecting workers and equipment.
How a Dike or Containment Berm Works
A dike or containment berm surrounds a storage tank and captures any leaked or spilled liquid within a controlled area.
Functions:
- Contains spills and prevents environmental contamination
- Helps detect leaks when liquid accumulates inside the berm
- Holds more than the total tank volume (per SPCC rules)
- Prevents discharge from spreading beyond the storage area
- Supports safe handling of hazardous materials
Facilities often combine containment systems with loading platforms to ensure safe access during loading and maintenance operations.
Applications
A dike or containment berm is widely used in:
- Fuel storage terminals
- Oil and gas facilities
- Chemical storage areas
- Construction sites with temporary tanks
- Industrial plants handling liquids
These environments also rely on truck loading systems and railcar gangways to safely manage material transfer operations.
Benefits and Importance
Using a dike or containment berm provides several important advantages:
- Prevents environmental damage from spills
- Supports compliance with SPCC and EPA regulations
- Helps detect tank leaks early
- Reduces cleanup costs and risks
- Improves overall site safety
Safety is further enhanced with systems like grounding and monitoring equipment and fall protection solutions when working around storage tanks.
Materials Used
Common materials used to construct a dike or containment berm include:
- PVC fabric for flexible containment
- Concrete for permanent structures
- Steel for industrial durability
- Specialized chemical-resistant materials
These materials can be customized to match different tank sizes and site requirements.
Safety and Compliance
A dike or containment berm is essential for meeting regulatory requirements such as:
- SPCC (Spill Prevention, Control, and Countermeasure)
- EPA regulation 40 CFR 264.175
- Secondary containment standards for fuel storage
Proper containment demonstrates a strong commitment to environmental protection and workplace safety.
