If it’s containers more than de minimus curbs are poor practice. Going up an
over a 20” dike with forklift is in the real world a classic cause of spills.
Sumps or a tank are much better. Added benefit is for spills generation of

In theory shut down in WA State unless response oriented construction.
I’ve seen one pickup at 4 over 2 project across from my pharmacy. Security? One

Elsewhere around town? I don’t know. One trip each of last two weeks. Did take
a fifteen mile
Hoping someone's brain is working better than mine.
I cannot seem to find the information on sizing a curb for containment of
flammable liquids and sprinkler water, I seem to remember a time frame for the
sprinkler water plus the largest container, but am having no luck locating is
Any help
There have been several project around my area that are scheduling
different contractors for different days.

If secondary containment is required (it's based on occupancy classifications
and quantities) the containment is for 20 minutes of sprinkler discharge and

certain quantities also would
I think you will need to look at a local level. Our field operations are in one
metro area, and we are covered by 8 stay-at-home orders (2 states, 1 city, 5
