Training is one of the most overlooked keys to bulk bag unloading success. Properly trained operators facilitate a safer, cleaner and more productive bulk bag unloading operation.
Key Bulk Bag Unloading Tasks That Require Specific Operator Training
Placing the Bulk Bag in the Bulk Bag Unloader: In most cases this is a simple task requiring only the attachment of the bulk bag lifting loops to the lifting frame used to place the bag in the bulk bag unloader. However, when certain types of liners are involved the operator must know how to safely use the bulk bag unloader’s liner tensioner to hold or wind up the liner during discharge thus preventing it from becoming entangled in downstream equipment.
Using Bulk Bag Unloading Equipment: The most common cause of bulk bag unloading problems is misuse of bulk bag discharging equipment. At best, not following the manufacturer’s operating instructions results in poor ingredient yield, unnecessary operator involvement to initiate or maintain ingredient flow and/or dusting. The worst scenario is when an operator’s lack of knowledge creates a safety hazard. This is most often seen when operators reach under an unsupported, suspended bulk bag to untie the outlet and initiate flow.
Removing the Empty Bulk Bag: A bulk bag that has just been unloaded is full of dust laden air. How the operator removes the bag can either maintain a dust free environment or create a dust clogged mess that in some circumstances results in a safety hazard.
Disposing of the Empty Bulk Bag: Even if a bulk bag is removed from the bulk bag unloader and transported to the point of disposal properly, problems can arise if an operator folds the bulk bag or otherwise expels the dust laden air in an uncontrolled manner.
Of course, the first step in successfully training operators is to develop well thought out Standard Operating Procedures (SOPs). With precisely defined operating objectives, tasks and expectations training success is greatly enhanced.
