Overflow: A Vital Consideration in Secondary Containment Measures

The necessity of housing toxic materials, via secondary containment measures, means acceding to the possibility of overflow.

Secondary containment devices must be larger than the original containment vessel. Generally, secondary containment units should be able to accommodate about one hundred and fifty percent of the volume of the primary vessel, while ten percent of the total of multiple containers is deemed acceptable.

Any systems available to rainfall must be able to accommodate up to 4.5 inches of accumulated rainwater, while secondary containment systems open to the potential onslaught of fire sprinklers must be able to bear such onslaught for no less than twenty minutes. More info: secondary containment
