Type A FIBC
Plain Bag - No Static Protection
- To transport non-flammable products
- No flammable solvents or gases present around the bag
Do not use:
- To transport flammable products
- When flammable solvents or gases are present around the bag
Type A FIBC are made from plain polypropylene or other non-conductive material. Static electricity is generated as products move over the inside surface of bulk bags when they are filled or emptied. An inherent electrostatic hazard with Type A bulk bags is that they do not have any mechanism for dissipating static electricity and will not prevent the occurrence of highly energetic, and dangerous propagating brush discharges (PBD). As there are no requirements for static control in this type of bulk bag, there are no electrostatic tests specified in standards and no requirements for labelling. Although it is permissible to label bulk bags as Type A FIBC, this is rarely done. Bulk bags that are not labelled as Type B, Type C or Type D, can be assumed to be Type A.
As there is no static protection provided by Type A FIBC, it is essential that they are not used to store or transport combustible materials or used in flammable or combustible environments. Many organic materials such as sugar, flour, corn starch, milk powder, wood pulp, etc. and chemicals such as bisphenol-A, benzoic acid, toner powders, etc. can form combustible dust clouds or layers that can be ignited by electrostatic discharges from Type A FIBC. The safe option for packaging materials of this nature is to use antistatic FIBC that offer full protection against electrostatic hazards, such as CROHMIQ Static Protective Type D FIBC.
Inert, non-combustible materials such as titanium dioxide (TiO2) are often used in processes that involve flammable solvents. There is a high risk of solvent vapours being ignited by electrostatic discharges from Type A FIBC. It is essential that only bulk bags with full static protection are used in any process that involves flammable solvents. In these situations CROHMIQ Static Protective Type D FIBC is the safe option.
