When it comes to handling hazardous liquids like chemicals, oils, or fuels, safety isn’t optional, it’s mandatory. One of the most important, yet often overlooked, components of spill prevention is secondary spill containment. But what exactly is secondary spill containment, why is it essential, and how can it help your business stay compliant and safe?
In this comprehensive guide, we’ll break down everything you need to know about secondary spill containment, explore different types of spill containment solutions, and explain why investing in the right products can protect your business, employees, and the environment.
What Is Secondary Spill Containment?
At its core, secondary spill containment is a safety system designed to catch and contain leaks or spills from your primary containers (like drums, tanks, or barrels). Think of it as a safety net that stops hazardous liquids from escaping and contaminating your workplace or the environment.
Primary containers can fail due to corrosion, accidental damage, or material defects. Secondary containment systems are designed to hold the entire volume of the largest container they protect, this means if a spill or leak happens, the secondary system prevents the liquid from spreading or causing damage.

Common Types of Secondary Spill Containment Systems
- Spill Containment Pallets: These pallets hold drums or containers and have built-in sumps to collect leaks. They’re ideal for indoor and outdoor storage areas.
- Containment Berms: Portable, flexible barriers often made of heavy-duty vinyl or PVC, perfect for temporary or emergency containment.
- Spill Containment Trays and Drip Pans: Smaller solutions for individual containers or equipment, useful for catching drips and minor leaks.
- Modular Containment Systems: Large, customizable units designed for tank farms, fueling stations, or industrial plants.
- Spill Kits: Ready-to-use kits with absorbent materials, gloves, and disposal bags, essential for quick spill response.
Why Is Secondary Spill Containment So Important?
1. Protect the Environment
Hazardous spills threaten soil, waterways, and wildlife. Secondary containment acts as a critical barrier, preventing pollutants from reaching the environment and ensuring your facility operates sustainably.
2. Meet Regulatory Requirements
Federal and state agencies, including the EPA and OSHA, require businesses that handle hazardous materials to have secondary containment in place. Compliance helps avoid fines, penalties, and legal issues. Understanding and implementing these requirements is key to maintaining your business’s reputation and operational license.
3. Improve Workplace Safety
Leaks and spills create slip hazards and expose workers to harmful chemicals. Proper containment keeps your facility safe, reduces accidents, and ensures employees can work in a secure environment.
4. Reduce Cleanup Costs and Liability
Without secondary containment, even a small leak can escalate into a costly environmental disaster requiring expensive cleanup and legal fees. Investing in secondary containment reduces your risk and protects your bottom line.
How to Choose the Right Secondary Spill Containment Solution
Choosing the best secondary containment system depends on several factors, including the types of liquids stored, container size, storage location, and regulatory standards. Here are some tips to help you decide:
- Assess Your Hazardous Materials: Identify chemical compatibility to avoid reactions with containment materials.
- Calculate Containment Capacity: Secondary containment must hold at least 110% of the volume of the largest container, or 10% of total volume, depending on regulations.
- Consider Your Storage Environment: Outdoor storage may require UV-resistant, weatherproof materials; indoor solutions might focus on ease of cleaning.
- Portability vs. Permanence: Berms offer flexible containment for temporary use, while pallets and trays provide permanent containment.
- Ease of Maintenance: Look for products that are easy to clean and inspect regularly.
Industry Applications for Secondary Spill Containment
Secondary spill containment is critical across many industries:
- Manufacturing Facilities: Contain hazardous chemicals used in production processes.
- Warehousing and Distribution Centers: Safeguard stored drums and tanks from leaks.
- Environmental Services: Prevent contamination during waste collection and disposal.
- Oil and Gas Operations: Contain fuel leaks at refineries, gas stations, and storage facilities.
- Healthcare and Laboratories: Protect against chemical and biohazard spills.
