S.6 Explosion of the gaseous sky of a fixed roof tank
Occurrence condition
The main events likely to cause an increase in internal pressure are:
heating of the gas phase of the tank following an external fire,
accidental pressurization following overfilling, malfunction of the pressure control device,
an explosion inside the vessel following the ignition of a flammable mixture,
a rapid increase in internal pressure due to a runaway reaction, or a mixture of incompatible products
The consequences of a capacity bursting are:
on the one hand the emission of a pressure wave, which results from the sudden expansion of the fluid contained in the capacity at the time of rupture and,
on the other hand the projection of the envelope fragments.
Other phenomena can be generated by the bursting of a capacity such as, for example, the formation of a ball of fire, or a secondary explosion, due to the expulsion of a flammable mixture during the explosion. bursting, or the atmospheric dispersion of toxic substances contained in the container.

The World Customs Organization (WCO) is an intergovernmental organization, which has its headquarters in Brussels, Belgium. With its members spread all over the world, the WCO is considered the voice of the international Customs community.
The WCO is renowned for developing international conventions, instruments and tools, in particular on the following subjects:
-
classification of goods,
-
customs valuation,
-
rules of origin,
-
collection of customs revenue,
-
supply chain security,
-
facilitation of international trade,
-
fight against fraud,
-
fight against counterfeiting by ensuring respect for intellectual property rights (IPR),
-
promotion of ethics
-
and sustainable capacity building for the implementation of Customs reforms and modernizations.
The WCO also manages the international nomenclature of goods known as the Harmonized System (HS) and the technical aspects of the World Trade Organization (WTO) agreements on customs valuation and rules of origin. Site : http://www.wcoomd.org/fr.aspx
