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.

FRONSEC
Strengthening cross-border capacity
for control and detection of CBRN substances
(Chemical - Biological - Radiological - Nuclear)
in North Africa - Sahel - Mauritania
CBRN substances, their dangers, and border detection and protection measures
A practical guide for border security personnel
This guide has been produced as part of the European Union (EU) Centers of Excellence Nuclear, Radiological, Biological, Chemical (CBRN) Risk Mitigation initiative.
It is developed within the framework of the EU-funded FRONSEC project entitled “Strengthening cross-border capacity for control and detection of CBRN substances” (IFS/2016/373-918) for the benefit of partner countries in the North Africa region, Sahel and Mauritania involved in the project.
The FRONSEC project is part of the CBRN Centers of Excellence initiative of the European Union. Launched in 2010, this initiative aims to identify and prevent the risks of CBRN threats, whether they relate to proliferation, theft, sabotage or smuggling, whether accidental, industrial or natural. The initiative promotes cooperation at national, regional and international level, with the aim of developing a common CBRN risk reduction policy, in the areas of crisis prevention, preparedness and management.
