Secondary Containment
Secondary containment refers to a system designed to capture and contain liquids that leak from primary containers such as tanks, vessels, or pipelines. It typically consists of bunds, dikes, catch basins, or coated containment areas that prevent hazardous liquids from reaching the environment.
Where is secondary containment used?
Secondary containment is required wherever hazardous substances are stored or handled, including:
- Oil & Gas – containment areas around large storage tanks.
- Petrochemical & Chemical – vessels and reactors equipped with spill containment systems.
- Power Generation – transformer bunds designed to contain leaking insulating oils.
- Marine & Offshore – chemical storage tanks and containment areas on platforms and vessels.
For you as an operator or asset owner, secondary containment is essential for HSE compliance, environmental protection, and avoiding costly cleanups or regulatory penalties.
Extra explanation and standards
Function – Capture and contain liquids until they can be safely removed or recovered.
Materials – Typically concrete or steel structures protected with chemical-resistant linings or coatings.
Standards
- EPA (United States) regulations and the EU Seveso III Directive require containment measures for hazardous leaks.
- ISO 14001 for environmental management systems.
Failure of secondary containment systems due to cracking, corrosion, or coating damage can result in uncontrolled releases and significant regulatory consequences.
Pinovo’s role in secondary containment
Pinovo’s dust-free vacuum blasting technology plays an important role in:
- Preparing containment areas and bund walls for protective coatings.
- Removing damaged coatings or corrosion without causing environmental contamination.
- Achieving Sa 2½ cleanliness and the required surface profile for long-term coating or lining adhesion.
- Working safely in ATEX environments where volatile liquids may be present.
Pinovo does not build containment systems, but ensures they are properly cleaned and prepared for protective coatings or lining repairs.
