In the early 1990's, Dr Laurence G. Britton, a highly respected process safety engineer with Union Carbide Corp. (later Dow Corp.), conducted a study of fire and explosion incidents that occurred when FIBC were being emptied. This article, originally published in the AIChE Process Safety Progress journal of October 1993, presents case histories for a number of incidents studied by Dr Britton together with his observations and findings. In relation to the specific hazard of ungrounded conductive Type C bulk bags, Dr Britton concluded "In particular it should be appreciated that the potential for operator grounding error and sudden nemesis can be very high". Since then, most major chemical companies have converted to ungrounded static protective, antistatic, non-conductive Type D FIBC. Read more...
Following three fatal dust explosions in 2003 alone, the US Chemical Safety & Hazard Investigation Board (CSB) launched a wide ranging study of industrial dust explosions.  This first issue of our Electrostatic Safety Review summarizes the findings of the CSB study and the action taken by OSHA and US Congress to implement new legislation and safety standards. It explains the implications for material handling in FIBC and how the use of CROHMIQ Static Protective Type D FIBC is a vital part of a company's combustible dust control program. Read more...
The second issue of our Electrostatic Safety Review outlines the development of conductive Type C FIBC and the later development of CROHMIQ, the world's first truly effective Type D FIBC fabric, which provides a safe solution to the hazards associated with ungrounded conductive bulk bags. Read more...
The third issue in our series of Electrostatic Safety Reviews describes the rigorous testing that is demanded by national and international standards such (IEC, CENELEC, NFPA, etc.) in order to prove the safety of FIBC intended for use in hazardous explosive environments. CROHMIQ Static Protective Type D FIBC are tested and qualified in accordance with the latest editions of these standards, and this issue explains how to identify static protective FIBC that have been qualified in this way. It also warns of the hazards presented by some FIBC that do not meet the essential safety requirements specified in the standards. Read more...
Companies that handle combustible powders in bulk bags, or empty products from bulk bags in environments where flammable solvents may be present rely on safe antistatic FIBC to prevent fires and explosions. Proving safety of an FIBC design prior to use is critical. This article explains the development of the CENELEC standards in Europe that first defined different types of static protective FIBC (Type A, Type B, Type C and Type D) and the development of the International Electrotechnical Commission (IEC) standard that specifies the rigorous test procedures required to prove the safety of FIBC intended for use in hazardous explosive environments.
