When working with bulk materials—especially powders, resins, and other fine particulates—one often overlooked hazard is static electricity. In industries like chemicals, pharmaceuticals, and food production, a sudden static discharge can ignite flammable dust or vapors, putting workers and facilities at serious risk.
That’s where static-safe FIBCs (Flexible Intermediate Bulk Containers) come into play.
In this blog, we’ll walk you through how static buildup occurs, the different types of FIBCs that prevent it, and how to choose the right antistatic bulk bag for your operation—especially if your business is based in the U.S. and adheres to OSHA and NFPA guidelines.
What Causes Static Buildup in FIBCs?
As bulk materials move across the inner surfaces of an FIBC during filling or discharging, friction between the particles and the bag can generate static electricity. If the charge isn’t dissipated, it can accumulate to dangerous levels.
Common triggers for static discharge include:
-
High-speed filling or emptying
-
Dry materials that easily generate friction
-
Low humidity environments
-
Lack of grounding or bonding
In the wrong conditions, a single spark can ignite combustible dust or vapor, leading to explosions or fires.
Understanding the Four Types of FIBCs for Static Control
There are four classifications of bulk bags when it comes to managing electrostatic hazards:
Type A –
Standard bulk bags with no static protection. Not safe for flammable or combustible environments.
Type B –
Made with insulating fabric that resists high breakdown voltage but still lacks grounding. Suitable for dry flammable powders but not for flammable vapors.
Type C (Conductive FIBCs) –
Made with conductive threads and require grounding during use. Safely dissipates static charge if properly grounded.
Type D (Static Dissipative FIBCs) –
Built with antistatic fabric that doesn’t require grounding. Ideal when grounding is difficult or when flammable vapors and gases are present.
Choosing between Type C and Type D depends on your application, material type, and grounding capabilities.
Where Are Antistatic FIBCs Required?
Static-safe FIBCs are essential in industries like:
-
Chemical manufacturing
-
Pharmaceuticals
-
Paint and coatings
-
Food processing
-
Plastics and resin handling
In U.S. operations, OSHA and NFPA guidelines often mandate specific anti-static protections in environments where flammable dust or vapors are present. Non-compliance can lead to fines, shutdowns, or serious accidents.
Key Features to Look For
When sourcing FIBCs for electrostatic protection, look for:
-
Grounding loops (for Type C)
-
Certificates of compliance (IEC 61340-4-4 or NFPA 77)
-
Clear labeling for bag type
-
Training on grounding practices
You should also work closely with your supplier to test and verify that the bag type matches your specific product and application.
