Risk of Electrostatic Ignition during FIBC Discharging Operations
This case study explores the factors behind the ignition source of a static discharge during an FIBC unloading operation. Flexible Intermediate Bulk Containers (FIBCs) are efficient, and transportation of dry bulk goods such as sand, fertilisers, plastic granules, seeds, resin and powder coatings, can be unloaded at a fast rate, with anywhere between 300 – 500kg typically in 30 seconds or less.
Used in agricultural, chemical, food and pharmaceutical industries, FIBCs have proven to be simple to use, cost-effective, strong, and can be collapsed after use and stored away. However, the use of FIBCs are not without their risks and when filling and emptying FIBCs in hazardous areas, electrostatic charge can accumulate on both the contents (product) and the fabric of the material itself. It is common under these circumstances for the rates at which static electricity charges are generated to exceed the rates at which the charges can relax, allowing the accumulation of a static electric charge to develop within the process.
