TY - JOUR A1 - Bethke, John A1 - Goedecke, Thomas A1 - Jahnke, Wolfgang T1 - Permeation through plastic dangerous goods packaging during transport in freight containers - Detection of potentially explosive mixtures in containers under normal conditions of carriage N2 - The key point within the scope of this research project was to find out whether there was a risk of creating an explosive atmosphere by permeation of flammable liquid compounds during transport of dangerous goods in freight containers under normal conditions of carriage. Therefore, all aspects that had an influence on the formation of such an atmosphere had to be considered. The most important influencing factors were permeation, air change in the freight container and ambient temperature. The first step was to investigate the permeation with different packaging materials, charge and temperatures. Furthermore, the air change rates of different freight containers were measured. A few climate tests with containers on ships, e.g. to Singapore, were performed to assess normal conditions of carriage. Another important point was measuring the solvent (toluene) concentration in the gas phase in a freight container loaded with plastic intermediate bulk containers (IBCs) filled with toluene. To confirm that the measured values were in the right range, the toluene concentration in the gas phase in a container was calculated with different packaging materials, air change rates and temperatures. The results of the measurements and calculations have shown that safety layers in the packaging wall, e.g. the copolymer of ethylene and vinyl alcohol (EVOH) and polyamide, can reduce the rate of permeation by more than a decimal power, but the lower explosive limit of toluene is easily reached within a few hours at 40°C charge temperature if there is no barrier.

This should be demonstrated by means of two examples of actual developments carried out by the Federal Institute for Materials Research and Testing (BAM). The Identification and diagnosis of concrete components is a major task in the maintenance of critical infrastructure, for instance concrete bridges with heavy traffic volume. A feasibility study investigates the application of RFID sensor systems for this task. The second example reviews the transportation of dangerous goods. Using modern technologies enables promising possibilities to reduce accidents and to avoid non-conformity with transportation regulations. Project results demonstrate an innovative technical solution for monitoring of dangerous goods transports with RFID sensor systems.

T1 - Securing of dangerous goods transports by RFID-tags with sensor-functionality and integrated database "GEFAHRGUT" information (SIGRID) N2 - The project SIGRID investigates and assesses possibilities to enhance the safety and security of dangerous goods transports through the use of the latest RFID-technology. This technology can be used to greatly enhance the transparency of the supply chain and aid logistics companies in complying with regulations. In the context of SIGRID, customized RFID-Sensor-Tags have been developed that monitor dangerous goods during transport and help to prevent hazards by allowing timely countermeasures. In the case of a dangerous goods accident, the available information about the type, amount and condition of the dangerous goods can be used to accurately inform the relief forces. Unavailable or inaccurate information represents a significant problem for the relief forces. This often leads to a delay in the rescue operation, because relief forces must be aware of the substances involved to protect themselves effectively against them. SIGRID aims to close this information gap. To verify the practicability of the underlying concepts, a demonstrator will be build and tests of realistic scenarios will be conducted.
