There are various safety hazards in the use of container bags (also known as ton bags, FIBC), which require comprehensive attention from production, use, storage, transportation and other aspects. The following are the main risk points and preventive measures:
1, Structural safety hazards
Insufficient load-bearing capacity
Risk: Overloading or aging of materials can cause breakage, leading to the dumping or falling of goods.
prevention:
Strictly use according to the marked safe load (such as 1000kg, 1500kg), and overloading is prohibited.
Conduct random inspections on new bags before use to test their tensile strength and drop resistance.
Avoid loading sharp and angular goods (such as metal parts) or using inner bags for protection.
Sling and seam fracture
Risk: The sling may not be sewn firmly, the material may wear out or age due to UV radiation, and it may suddenly break during loading and unloading.
prevention:
Check whether the stitching between the sling and the bag body is uniform and firm.
Regularly replace aging and worn container bags (especially those exposed outdoors for a long time).
Avoid puncturing the bag body when using a forklift.
2, Operation and loading/unloading risks
Improper lifting method
Risk: Single sling lifting, excessive hook angle leading to unstable center of gravity and falling.
prevention:
Ensure that all lifting straps are evenly stressed and use specialized hangers (such as four hook lifting devices) to maintain vertical lifting.
Personnel are prohibited from standing below the lifting area.
Forklift operation error
Risk: Forklift teeth piercing the bag body or causing tipping due to impact.
prevention:
Forklift operation should be smooth, and the forks should fully support the bottom of the bag.
Avoid sudden stops and turns, and use protective plates if necessary.
3, Storage and stacking risks
Stacking too high or tilted
Risk: Unstable stacking and collapse, injuring personnel or damaging goods.
prevention:
According to the load-bearing design of the bag, stack the layers reasonably (usually ≤ 3 layers).
Adopting a "staggered" stacking approach to enhance stability, avoiding proximity to channels or edges.
Environmental factors have an impact
Risk: Material aging caused by exposure to sunlight and rain; The humid environment causes the goods inside the bag to become damp, clump, or deteriorate.
prevention:
Indoor storage, avoid direct sunlight and soaking in rainwater.
Chemicals need to be ventilated to prevent volatilization or reaction.
4, Special cargo risk
Flammable and explosive dust environment
Risk:
Electrostatic discharge can cause explosions (such as loading powders or granular chemicals).
The electrostatic characteristics of different types of container bags are different (conductive, anti-static, insulating), and misuse may be fatal.
prevention:
Choose compliant anti-static container bags (such as D-type, C-type) according to the environment, and strictly ground them.
Avoid operating in hazardous areas and use explosion-proof tools.
Toxic or corrosive substances
Risk: Leakage may cause pollution or personal injury.
prevention:
Use a well sealed lining and check that the bag body is leak free.
Operators should wear protective equipment (gloves, goggles, gas masks).
5, Transportation process risk
Wear and tear during long-distance transportation
Risk: Friction and bumps with the carriage can cause damage.
prevention:
Secure the vehicle's interior packaging bag and use straps or inflatable airbags to prevent movement.
Strengthen the straps and seams before long-distance transportation.
Cross border transportation compliance
Risk: Non compliance with destination country standards (such as EU CE certification, US FDA food grade requirements).
prevention:
Confirm that the material and labeling of the container bags comply with local regulations before export.
6, Daily inspection and management
Establish an inspection process
Check before each use:
Check for wear, tear, and fading (signs of UV aging) on the straps and bag body.
Is the seam open and is the base of the sling secure.
Scrap criteria: presence of holes, severe stains (affecting strength), deformation or fracture history of the sling.
personnel training
Train operators to standardize loading, unloading, and storage knowledge, especially emergency handling in hazardous material scenarios.
Special precautions: Electrostatic safety
Conductive type (C type): Strict grounding is required, otherwise sparks may be generated.
Anti static type (D type): does not require grounding, but is only suitable for low-risk environments.
Insulation type: Prohibited for use in flammable dust environments!
Consulting experts: Choose the appropriate type based on specific goods (such as carbon powder, grain, chemicals) and the environment.
Summary: The safe use of container bags requires comprehensive attention to four key points: quality compliance, standardized operation, environmental matching, and regular inspection. Especially when dealing with hazardous materials, it is necessary to follow relevant industry standards (such as ISO 21898, EN 1634). Enterprises should establish a full process management system, which requires recording and tracking from procurement to scrapping to eliminate hidden dangers.
