How Much Does a 55-Gallon Drum Weigh? It Depends!
The weight of a 55-gallon drum isn't a simple answer; it varies significantly depending on what's inside. While the drum itself has a weight, the contents dramatically influence the overall mass. Let's break down the different factors contributing to the total weight:
Weight of the Empty Drum
A standard 55-gallon drum, made of steel, typically weighs between 30 and 50 pounds. This variation stems from the thickness of the steel used in manufacturing, the presence of any reinforcing rings or baffles, and the type of drum (open head, closed head, etc.). Some drums are made from lighter materials like plastic, resulting in a lower empty weight, perhaps in the range of 15-25 pounds.
Key takeaway: The weight of the empty drum itself is only a starting point.
Weight of the Contents: The Major Variable
The weight of the contents is the most significant factor determining the total weight of a filled 55-gallon drum. This weight depends entirely on the material being stored:
-
Water: One gallon of water weighs approximately 8.34 pounds. Therefore, 55 gallons of water would weigh roughly 458.7 pounds (55 gallons x 8.34 pounds/gallon). Adding the weight of the drum (let's assume 35 pounds), the total weight would be approximately 493.7 pounds.
-
Oil: The weight of oil varies greatly depending on its type (crude oil, motor oil, etc.). A common density is around 7.5 pounds per gallon, resulting in a weight of around 412.5 pounds for the oil alone. This would bring the total weight, including the drum, to approximately 447.5 pounds.
-
Other Materials: Chemicals, solids, and other substances will have vastly different densities, and therefore vastly different weights. Always refer to the Safety Data Sheet (SDS) for the specific material to determine its weight per gallon.
Calculating the Total Weight
To determine the total weight of a filled 55-gallon drum, follow these steps:
- Find the weight of the empty drum: Check the manufacturer's specifications or weigh an empty drum using a scale.
- Determine the weight of the contents: Consult the material's SDS for the weight per gallon. Multiply this by 55 gallons.
- Add the weights together: The sum of the empty drum weight and the weight of the contents equals the total weight.
Safety Considerations
Always handle 55-gallon drums with appropriate safety precautions. Their weight, particularly when filled, makes them difficult to move and handle safely without the proper equipment and training. Remember that the center of gravity can shift unexpectedly with uneven filling, further increasing the risk of injury.
Conclusion
The weight of a 55-gallon drum is highly variable and depends heavily on its contents. Always calculate the total weight using the steps described above, considering both the weight of the empty drum and the specific gravity of the substance being stored. Remember to prioritize safety when handling these heavy containers.
