Type C Static Control versus Type D Static Control
The buildup of electrostatic charges is a common occurrence in everyday life. All of us have experienced a discharge or shock from static electricity at some point. That “zap” is known as a discharge and can prove to be catastrophic in certain environments.
Emptying and filling Super Sack® Containers with dry, flowable material is the perfect recipe for creating a buildup of electrostatic energy and if you are working in a hazardous, combustible, or flammable environment, one discharge can cause a fire or even an explosion. That is why B.A.G. Corp.® offers Static Control Containers and you have two versions to choose from, Type C or Type D. Which one works for you?
Type C Flexible Intermediate Bulk Containers (FIBC) are conductive. That means they actually have filaments, woven into the fabric, that conduct electricity. The conductive filaments in a Type C bag control the buildup of static electricity by channeling all of the energy to the same place, and that place is called a grounding tab. The user simply connects the grounding tab on the bulk bag to a known electrical ground and all of the static will be conducted away from the bulk bag and safely into the ground, providing an extremely reliable solution. This is a great system because it removes all doubt. We can’t see the electric charges, but we can see if the bulk bag is connected to a ground and know that it is safe. However, Type C Super Sack® containers become just another FIBC if they are not grounded properly.
Type D FIBCs are dissipative. Which means they allow the electrostatic charges to slowly dissipate into the ambient air. The Type D bulk bag is manufactured with Crohmiq™ Blue fabric that is engineered specifically for static control. The advantage of this bulk bag is you never have to remember to connect or disconnect it to a ground, eliminating operator error.
One spark from an electrostatic discharge in the wrong environment can be catastrophic. Give us a call at (800) 331-9200 if you have any questions about the proper Static Control Container for your application.
