Secondary Containment for Chemical Delivery Vehicle Areas
Secondary Containment for Chemical Delivery Vehicle Areas
(OP)
Hello,
We have Outdoor storage of Hydrochloric Acid (10m3) and Sodium Hydroxide (10m3) on our project site for a water treatment process.
The delivery vehicle for both chemicals has volume of 25m3.We have provided spill containment for the storage tanks themselves, but what I'm trying to establish is whether the vehicle unloading area should also have spill containment?
I have checked the NFPA codes and there is no requirements.Does anyone have any experience or know of any other codes and standards that I should be looking at?
Thanks,
Tom

1. Fire codes
2. Environmental codes.
And, where would the HCl/ NaOH go if it gets spilled?
I work in the chemicals industry.. we would provide spill containment for a premant facility used for tanker of loading to prevent ground water contaimination in the event of a spill

If the chemicals spilled at the moment, they would drain into the storm drainage system.
Can you refer to any specific environmental codes which give any guidance on the design of the spill containment area?
How would I go about sizing a collection basin, would this need to sized to contain the entire volume of the tanker should the whole contents spill out??
I assume that the collection basin would have to be drained of rainwater on a regular basis to keep it empty?
Thanks again,
Tom

The entire tanker plus firewater, if needed, plus a reasonable amount of rainwater. The area will have to be washed down in case of a spill, right?.
Also, the first part of a rain (1st 1/4" or 1st 30 minutes - I've seen both) is usually contained, observed and tested for contamination prior to release.
Most engineering firms that cater to the chemical industry can bang out a design pretty quick. It's old hat.
Good luck,
