More Book Details

Description of the Book:

In the case of a large number of companies or laboratories dealing with explosives manufacturing, a lot of small explosive charges waiting for being tested are stored in reinforced structure buildings with a specific design. The purpose of this study is to determine hazardous areas contours, according to the French Regulation definitions, in the case of an aboveground multicellular storage facilities involving 1.1 Hazard Division material. The limits of such hazardous areas are corresponding to an over-pressure threshold, when the blast is the only effect to fear. The main feature of such storages is the low loading density lying between 0.01 kg/m3 and 0.1 kg/m3. Often, a barricade is built up in front of the magazine chambers to catch the fragments if an accidental event occurred. Its influence on hazardous areas shape and sizes, due to the blast, will also be assessed. The best way to reach this goal was to perform scale model tests in order to record over-pressure – time history all around the scale model, with piezoresistive gauges.

Hazardous areas limits as function of Q 1/3 (Q : TNT equivalent charge weight) have been deduced from these tests
