Are there any correct methods to store drums?
Yes, there are certain procedures to be followed while storing drums, especially in depots, where they could be stored over long periods of time. Storage of oil drums – Normally an oil drum stored vertically has a certain gap between the top oil level in the drum and the top of the drum. This gap is air-filled. During the daytime, particularly in hot regions, the oil expands causing air to be pushed out of the drum. At nighttime, the oil shrinks causing air to be breathed into the drum. If there is a lot of humidity in the air or a layer of water on the drum, there is ingress water into the drum, which settles down slowly in the drum. To avoid this, the drum should always be stored horizontally with the oil level higher than both vents which would be at the 3.0’ clock and 9.0’ clock positions as shown below.
