Flammable Liquids
This is another opportunity for facility sitting to apply specific metrics to the exercise. Just as the distances for Tank Truck and Rail Car Unloading/Loading facilities are intended to protect our bulk storage tanks, this is intended to prevent BLEVE(s) that could impact the above-ground storage tank.

In some cases, we can actually put specific measurements in our "facility siting" analysis. Take, for example, an old but often missed distance between the tank truck/railcar and the closest aboveground tank. (emphasis by me)
Here is what this looks like: SAFTENG Members can download the full image without watermark and the analysis of NFPA 30 as it applies to these requirements...
A common question we get regarding flammable liquids is: Do we have to ground and bond non-conductive containers smaller than 5 gallons?
The proper question should be... what do we need to do to SAFELY transfer flammable liquids into non-conductive containers that are 5 gallons and smaller?
The British Columbian Worker's Compensation Board standard says it best and offers us four (4) means/methods by which we can control static when filling these smaller, non-conductive containers.
Did the 2024 edition of NFPA 77, Recommended Practice on Static Electricity establish a norm for "relaxation time"? In six (6) different sections across five (5) chapters, the recommended practice cites "30 seconds" as a "suitable precaution." (emphasis by me)
Major changes in the 2024 edition include:
The protection provided by the 2021 IFC is to prevent flammable and combustible liquids from becoming ignited. This is accomplished by one or more of the following layers of protection: |
