Safety Specifications for FIBC Lifting, Forklift Operation, and Pallet Stacking

Core Principle: Ensure Uniform Stress Distribution and Strictly Prohibit Overloading.

All Lifting Points Must Be Engaged: You must use all the lifting loops designed for the bag (usually 4 loops, or sometimes 1, 2, or 8 depending on the design). Strictly prohibit single-loop lifting, double-loop lifting on a four-loop bag, angled lifting, or off-center loading. Uneven stress will cause the fabric to tear under the immense weight of the payload.

Position Hooks Centrally and Vertically: The crane or hoist lifting hook must be placed directly in the center of the lifting loop strap. Never hook the seam, the edge corner, or twist the strap. A twisted strap reduces the lifting capacity by up to 50% and focuses all the weight onto a few threads.

Strictly Control the Lifting Angle: The included angle between adjacent lifting loops should be ≤ 90°. It must absolutely never exceed 120°. Physics dictates that as the angle increases, the lateral tension on the loops increases exponentially, easily leading to overload and sudden breakage even if the bag is under its weight limit.

Maintain Smooth and Steady Operations: Dynamic loads are far more dangerous than static loads. Avoid sudden starts, abrupt stops, or swinging the load mid-air. A 1000kg bag dropped suddenly for even just a few inches can generate a dynamic force of over 2000kg on the straps. Personnel are strictly prohibited from standing, walking, or working under a suspended load.

Mandatory Pre-Use Inspection: Make it a strict company policy to immediately cease using any bag exhibiting damaged lifting loops, unraveled seams, torn fabric, severe abrasions, or signs of UV aging and hardening.

Respect the Load Limits: Never exceed the Safe Working Load (SWL) marked on the bag's certification label, nor the capacity of the lifting equipment.

Safety Specifications for FIBC Forklift Operation

Core Principle: Maximize Stability and Prevent Crushing.

Ensure a Solid Foundation: Never stack FIBCs on uneven, sloped, or damaged ground. If using pallets, ensure the pallet is structurally sound and rated for the static weight of multiple stacked bags.

Implement Pyramid Stacking: If the bags are free-standing (not supported by warehouse racking or walls), they should be stacked using a pyramid method. The base layer should be wider, with subsequent layers stepped inward to ensure self-supporting stability.

Interlocking Configuration: When stacking square-baffle bags, use an interlocking or "brick-laying" pattern where possible, rather than stacking them directly in perfectly vertical columns. This binds the stack together and prevents individual columns from tipping over.

Observe Maximum Stacking Heights: Pay attention to the bulk density of the material and the bag's structural rating. Typically, FIBCs should not be stacked more than 3 to 4 high. Over-stacking puts immense hydraulic pressure on the bottom bag, leading to bursts and full stack collapses.

Safety First: A Final Note

Safety in bulk material handling is not just a regulatory requirement; it is the foundation of a profitable, efficient, and ethical business operation. By strictly adhering to these operational guidelines, your team can dramatically extend the lifespan of your packaging materials, protect your valuable inventory, and most importantly, guarantee that every worker goes home safely at the end of their shift.
