IBC Totes, Leaks, and What to Know
Intermediate Bulk Container (IBC) totes are known for their strength, trustworthiness, and versatility. Even so, there is a risk of the totes leaking, which can lead to potential safety concerns if not addressed promptly. This concern for leaks increases with the IBC’s age and amount of use, how well it is maintained, and if the cargo is not fully compatible with the materials the tote and its components are made from.
Why Do IBC Totes Leak?
Several working factors can contribute to why an IBC tote may develop a leak:
- Faulty Drain Valve: The most common issue reported by users leading to a leaky IBC is from a fault in the built-in drain valve on the container. This occurrence, however, is most often due to wear and tear over time or by replacing the manufacturer’s valve with a non-standard or non-identical valve.
- Improper Venting: IBC totes need proper venting to prevent the build-up of pressure or a vacuum due to temperature fluctuations, pumping, or the off gassing of a chemical cargo. Without adequate venting, this pressure can cause the tote to either bulge or collapse, leading to tote failure or leaks at seals or in the plastic. To avoid this, most modern IBC products feature an automatic vent relief feature built into the lid.
- Structural Damage: IBC totes are designed to withstand impacts and strains during transport and handling. However, damage can still occur., and structural damage to the IBC tank can cause it to leak. This makes a thorough inspection important after an IBC has sustained a significant impact or fall.
How to Handle IBC Tote Leaks
- Regular Inspections and Leak Tests: Regular inspections and leak tests will help in detecting leaks early before they cause a bigger problem. An IBC tote leak test often involves sealing off openings and applying a layer of water and soap around its exterior at potential leak spots and seeing if bubbles begin to form due to air escaping from the container.
- Repair: If a leak is detected, determine the root cause and promptly repair. Depending on the IBC’s build material, the location and severity of the leak, different repairs may be needed. Components such as the drain valve, O-rings, and the lid can be replaced. OEM replacement parts are recommended or should otherwise match the original specifications to maintain the integrity of the tank. If the leak is in the IBC tank body, repair is often recommended to be done by a certified professional and a speedy replacement of the IBC is recommended. Repairing leaks in the tote body can prevent cargo loss but will render the IBC unsuitable for further work applications and transit.
- Proper Venting: Proper venting is often done by using a dedicated IBC lid with a built-in vent, by opening the lid, or removing a bung to release excess pressure. Ensuring the IBC is venting or vented properly is vital to preventing the build-up of excess pressure or a pressure-less vacuum scenario inside the tote, thereby reducing the chances of leakage and tote failure.
- Use UV-Resistant Totes: If the IBC tote is stored outdoors, using a UV-resistant plastic tote can reduce long term damage from sunlight, thereby reducing the risk of developing leaks over years of service. Most modern plastic IBC totes, including the ones we offer, are made with UV-stabilizers to resist sunlight damage.
In conclusion, while IBC totes are generally robust and reliable, there can be a risk of developing leaks, but in many cases, can be avoided or repaired. Regular inspections, leak tests, proper use and maintenance can help detect and address leaks early, ensuring the safe and efficient use of these containers.
