The Challenge of Investigating the Dust Explosion Properties of Nano-Powders and Highly-Active /Highly-Toxic substances

摘要

The safety laboratories of the Swiss Safety Institute in Basel (former Ciba-Geigy and Sandoz) perform since more than 30 years explosibility, combustibility and thermal stability tests on chemical substances in dust form. While testing nano- materials and highly active chemicals, particles of these materials may cause health damage in very low concentrations in the air. An open handling is not recommended. As an ongoing project, new devices are being developed in order to test the thermal stability and explosive properties of these materials.
