Have you ever seen several full tanker trailers parked without their mode of transport under them or a railcar with the Class 3 Flammable placard hooked up to the process and being used as a storage tank? Although OSHA’s 1910.106 makes no specific prohibition against this practice, I would like to point out that the International Fire Code (IFC) of which many states in the USA have adopted as their state fire code does make a SPECIFIC PROHIBITION of using railcars or tank trucks as “storage tanks”.
