1 Single Trip FIBC Safe Handling Information

2 Single Trip FIBC Safe Handling Information This presentation is too emphasis the critical handling issues of Single trip Bulk Bags Single Trip Bulk Bags are inherently lighter in construction than multi trip bags. The Fertiliser industry has not traditionally used Single trip Bulk Bags and incoming reports and samples provided indicate to BHA that they are being subjected to the same harsh treatment as the more robust Multi Trip designs that have previously been used. Exposed to long periods of sunlight Lifted with sharp tines or hooks Snagged up against gang walks and truck sidings Transported whilst elevated on forklift and tractors at speeds across rough ground Lifted with incorrect equipment and or not lifted by all loops provided All BHA bags are marked Test Standard: AS , they are pretested and certified in accordance with the Australian Standard. Single trip bags: Top lift or loading test- 5 times Safe Working Load (SWL), Stacking test -4 x SWL, Drop test 0.5m loaded to SWL, Cyclic Top Loading 30 cycles at 4 x SWL+ 1 x 5 SWL At the time of bag manufacture quality control tests are carried out on all materials throughout all parts of the process up to and including the completed bag. All of BHA labels have instructions for use in the form of pictograms.

3 Quality Controls in place during the manufacture of Bulk Bags Process Raw Material Quality Control Process - COA or sampling check as per approved spec. In every step of the manufacture of Bulk Bags there are stringent Test procedures along with Quality Control procedures to ensure they comply with the approved and Standard tested design. Multi and Monofilament Production Weaving - Webbing Tapeline - Tape Production - Every lot when receive Spec,Denier, width, tensile & elongation - When change spec, start the new production lot - When change the work shift in a day Tensile strength: test the fibre strength of the yarn used in the material and webbing. Weaving - Fabric construction, weight, tensile & elongation* - Fabric : when start the production lot tensile test* every roll. - Webbing : when start the production lot tensile test* every production lot ( spec). Fabric weight: Fabric is manufactured to the specified GSM UV tests: Are conducted on fabric to determine UV resistance after UV exposure based on standards requirements. Lamination Cutting - Body, bottom panel, bottom spout, webbing Fabric construction, width, weight after lamination (g/m2) adhesion test. - When start the production lot,after finished adjust the machine. - Every roll when finished. Fabric spec, cutting length, size,fabric appearance - First bag when start the new cutting lot - Sampling check when change the fabric lot Top lift Tests : For each production run a completed bag is filled and top lift tested to ensure they pass the required minimum safe working load. Body Printing Fabric size, Printing pattern and color, position - First piece when start the new production lot - Sampling check when change the fabric lot Sewing In process check until finish. Bag component, Sewing pattern, Dimension as per bag 's specificatiion. - First bag when start the new production lot - Sampling check 5 Bags./lot / shift Finished Bag Bag strength (Top lift test ) - 1 bag / shipment Packing and Palletization

4 Typical Issues UV Damage UV degradation is by far the single most contributor to bag failures within the fertiliser industry. BHA bulk bag materials are loaded with appropriate UV inhibitor to comply with the industry standards. The standard stipulates that bag should not be stored in sunlight. If the bags have to be stored outside, full or empty, they should be on pallets to keep them away from ground water, covered with black polythene which reduces UV ray penetration by over to 90%

5 Lifting Bulk Bags Regularly check fork tines for sharp edges and burrs. File down or cover with poly or cardboard tubing if identified. 4 Loop Bulk Bags are designed to be lifted by the 4 loops in an even position to ensure load is evenly distributed

6 Lifting Bulk Bags Typical Issues Do not lift a 4 loop Bulk Bag with loops on only 1 tine or hay bail spike. Do not use rope or chains to gather the loops prior to lifting.

7 Examples of causes of Bag Failures Part rupture of lifting loop on a blunt object. Loop may have been sandwiched between two objects during transport or storage. Rope burn on loop. Caused by gathering loops together by rope for lifting. Part rupture of lifting loop by a sharp object. Commonly from sharp edges on fork tines. Severe abrasion to loops. Commonly caused by rough/sharp fork tines.

8 Examples of causes of Bag Failures Glancing rupture of lifting loop on semi sharp object. Loop may have been sandwiched between truck tray, post, super spreader, shed wall or other semi sharp object while being moved on fork tines. Rupture of lifting loop by a pointed blunt object. Loop may have been sandwiched between the end of the fork tine and shed wall, post, truck body, super spreader or another blunt object while attempting to thread forks through loops.

9 Trip Examples of BHA bag labels All BHA Bulk bags carry a label sewn to the top or top side of the bag. Multi trip Single Trip Single Point Lift Design/ Single

10 Explanation of label information SWL- Safe working load of the bag. Safety factor- The test loading of the FIBC (A FIBC with a SWL of 1000kg and safety factor 5:1 has been test loaded at 5000kg without breakage as per page 2) Test certificate number- Unique number assigned to the type test. Test certificate date- Date of test Test standard- The FIBC standard the type test followed. For Australia, normally Australian FIBC Standard(AS3668) or Australian Code for Transport of Dangerous Goods standard (ACTDG) If food grade /rating- this is filled in for food grade rated bags only. AFIBCA logo- AFIBCA directive - to encourage industries to use safe products and handling practices. The Australian Standard A for FIBC's was born out of this and was adopted by industries as the main guide used when choosing or using FIBC. BHA is a founding member. FIBC class- Multi trip the FIBC can be used for multiple fills and decants. Single trip the FIBC can only be filled and decanted once but can be lifted multiple times during the one fill. Handling pictograms- Very important information, the do s and don'ts of handling the FIBC. Manufactured by- The name of the manufacturer or supplier of the bag. Supplier reference number- Unique number assigned to this design and batch for reasons of traceability.

11 Critical handing information BEFORE LIFTING ANY FILLED BAGS, IT IS IMPORTANT THAT:- Always attach the lifting device to all of the lifting points on the bag - ensuring the load is evenly spread. Ensure lifting hooks, tines, shackles and associated devices have no sharp edges. Inspect for any damage which may render the FIBC UNSAFE. Please notify your Dealer or Agent if you consider a FIBC unsafe. The lifting straps plus other lifting devices are positioned according to recommendations and show no signs of deformation or deterioration. The hooks or Forklift tines employed for lifting should have round edges or be protected. The stability of the load is checked when the bag is to be moved or stacked on a pallet. The stated load weight is checked against the safe working limit (SWL) before lifting the bag. The forklift or lifting boom is checked to have adequate capacity to carry suspended load.

12 Do Critical handing information Don't Read instruction labels. Check the discharge spout is closed correctly before refilling. Insure the filled FIBC is stable. Use lifting gear with sufficient SWL capacity to take the suspended load. Adjust fork lift tines to the correct width for the FIBC being handled. Tilt the mast of the fork lift truck rearwards to an appropriate angle. Consider appropriate dust control measures. Protect FIBC s from rain and/or sunlight. Ensure FIBC s are adequately secured in transportation. Lift bags only as instructed on label. Use spreader bar/frame if required to enable loops elevate vertically. Do Not exceed the SWL under any circumstances. Do Not stop or start suddenly when transporting loaded FIBC s. Do Not subject FIBC s to snatch lifts and jerk stops. Do Not drag FIBC s. Do Not allow personnel under suspended FIBC s. Do Not allow the FIBC to project over the side of a vehicle or pallet. Do Not tilt the mast of the fork lift forward. Do Not withdraw fork lift tines before all the load on the lifting device is removed. Do Not stack FIBC s unless their stack ability is certain and labeled. Do Not use FIBC s in new applications without consulting your supplier. Do Not re use bags labeled as Single Trip Only or Use Once Only. Do Not use FIBC s with cuts more than 1 cm length in any of the load bearing fabrics. Do Not use single boom e.g. hay bale spike, rope or chain to lift 4 loops pulled together.
