Primary containment of hazardous materials is required in dozens of very different environments. The risk factors and characteristics of these harmful substances can vary greatly as well. Regardless of the challenges of primary containment, it’s rarely sufficient for a safe working or storage environment. Thus, secondary containment is needed. Secondary spill containment is the practice of designing a backup system that captures liquids or powders that are released from the primary containers or containment units. This takes the form of containers, pads, and berms placed under and around tanks, pipes, processing units, and even delivery trucks, to keep spills from spreading. These containment devices need to be:
- Able to resist the corrosive or reactive effects of certain materials
- Durable enough to withstand heat, being driven over, and abrasive surfaces
- Flexible and easy to adjust to fit the exact size and space that requires secondary containment.
Secondary containment equipment is essential for the safety of both workers and the environment. Even minor drips and leaks can easily reach waterways and settle into the soil surrounding the spill site. Spills of costly chemicals and product ingredients can result in financial losses as well. Instituting a secondary containment plan for your facility or business also improves employee safety, avoiding OSHA violations and the resulting fines. Let’s explore the demands of spill containment from specific industries, find the facts on calculating the material needed for custom pads, and learn how to maintain these safety devices over long term use.
