How Much Does a Full 55-Gallon Drum Weigh? It Depends!
The weight of a full 55-gallon drum is highly variable and depends entirely on the contents of the drum. A 55-gallon drum itself only weighs between 30 and 50 pounds, depending on the material (steel, plastic, etc.) and its construction. The vast majority of the weight comes from whatever it's filled with.
To accurately determine the total weight, you need to know the density and volume of the substance within the drum. Here's a breakdown of how to calculate this, followed by some common examples:
Calculating the Total Weight
The formula is straightforward:
Total Weight = (Density of Substance x Volume of Substance) + Weight of the Drum
-
Density of Substance: This is typically measured in pounds per gallon (lbs/gal) or kilograms per liter (kg/L). You can find density information in material safety data sheets (MSDS) or online resources for specific substances.
-
Volume of Substance: For a full 55-gallon drum, this is approximately 55 gallons (or its equivalent in liters, approximately 208 liters). Keep in mind that the drum might not be completely full, leading to a slightly lower volume.
-
Weight of the Drum: As mentioned, this ranges from 30 to 50 pounds, depending on the drum's material and type.
Examples of Different Contents and Their Weights:
Let's look at a few examples to illustrate the significant variation in weight:
1. Water:
- Density of Water: Approximately 8.34 lbs/gal
- Weight of Water in a 55-gallon drum: 8.34 lbs/gal * 55 gal = 458.7 lbs
- Total Weight (assuming a 40-lb drum): 458.7 lbs + 40 lbs = 498.7 lbs
2. Gasoline:
- Density of Gasoline: Approximately 6 lbs/gal (this varies slightly depending on the blend)
- Weight of Gasoline in a 55-gallon drum: 6 lbs/gal * 55 gal = 330 lbs
- Total Weight (assuming a 40-lb drum): 330 lbs + 40 lbs = 370 lbs
3. Heavy Oil:
- Density of Heavy Oil: This can vary greatly, but let's assume 9 lbs/gal as an example.
- Weight of Heavy Oil in a 55-gallon drum: 9 lbs/gal * 55 gal = 495 lbs
- Total Weight (assuming a 40-lb drum): 495 lbs + 40 lbs = 535 lbs
4. Dry Material (e.g., grains):
The weight of dry materials is often expressed in pounds per cubic foot, requiring a conversion to gallons. This calculation is more complex and depends on the bulk density of the specific material.
Safety Considerations
It's crucial to always consult the appropriate MSDS for any substance stored in a 55-gallon drum. This document will provide essential safety information, including the correct handling procedures and the substance's precise weight. Never attempt to lift or move a drum without proper equipment and understanding of its weight; improperly handling heavy drums can lead to serious injury.
This information is for general knowledge only. Always prioritize safety and consult appropriate safety data sheets before handling any 55-gallon drum.
