Compressed natural gas (CNG) is a widely used automotive fuel in a variety of countries. In case of a vehicle fire where the safety device also malfunctions, a failure of the CNG automotive cylinder could occur. Such a cylinder failure is associated with severe hazards for the surrounding environment. Firstly, a comprehensive analysis is given below, summarizing various accidents involving CNG automotive cylinders and their consequences. In an extensive experimental program, 21 CNG automotive cylinders with no safety device were tested. Of the 21, burst tests were carried out on 5 Type III and 5 Type IV cylinders. Furthermore, fire tests with 8 Type III and 3 Type IV cylinders were conducted. Apart from cylinder pressure, inner temperature and cylinder mantle temperature, the periphery consequences, such as nearfield blast pressure and fragmentation are documented. The maximum measured overpressure due to a Type III cylinder failure was p = 0.41 bar. Each traceable fragment was georeferenced. All-in-all, fragment throw distances of d > 300 m could be observed. As one key result, it can be stated that the tested Type IV CNG cylinders showed less critical failure behavior then the Type III cylinders under fire impingement.
Again and again in case of a fire a bursting of acetylene cylinders occure. In the case of such a cylinder failure, these represent an enormous threat to fire and rescue services. BAM has been dealing for many years with the effects of acetylene cylinder failure. The presentation introduces BAM's experimental work in this area and outlines various options for action to reduce the risk for fire and rescue services. In the beginning BAM as well as the experimental possibilities at the BAM TTS are presented.
Lithium Ion Batteries - Europe and Germany in general and BAM with safety aspects in particular
(2019)
The article introduces the BAM as well as the experimental possibilities at the BAM TTS in the first part. The second part explains general aspects of the electromobility strategy and the research landscape on lithium batteries in Germany and Europe. In the last part of the presentation current investigations on the safety of lithium batteries as well as perspectives planned investigations of the BAM in this area are presented.
