What is a secondary containment system?
Herein, what is the meaning of secondary containment?
Secondary containment is defined as a means of surrounding one or more primary storage containers to collect any hazardous material spillage in the event of loss of integrity or container failure.
Furthermore, what needs secondary containment? The secondary containment system “must have sufficient capacity to contain at least 10% of the total volume of the primary containers or 100% of the volume of the largest container, whichever is greater.” 55 gallons is greater than 11 gallons, so you would need to have secondary containment for 55 gallons.
In this manner, what is the primary function of secondary containment?
Secondary spill containment is the containment of hazardous liquids in order to prevent pollution of soil and water. Common techniques include the use of spill berms to contain oil-filled equipment, fuel tanks, truck washing decks, or any other places or items that may leak hazardous liquids.
Do 55 gallon drums need secondary containment?
Each 55-gallon drum stored indoors needs to have its own 66-gallon capacity secondary containment pallet. While you can always go above and beyond what is required, you really only need to size a secondary containment system to contain the single largest container plus freeboard for precipitation.
