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
E-LEARNING
Faced with the global pandemic linked to SARS-CoV-2, the FRONSEC project continued activities thanks to the e-learning platform developed in partnership with Citrus and support of the 7 countries of the North Africa region, Sahel and Mauritania.
The FRONSEC project, "Strengthening cross-border capacity for control and detection of CBRN substances", has benefited since October 2019 from the involvement of all the stakeholders of the 7 countries of the North Africa region, Sahel and Mauritania.
In parallel with the activities of the FRONSEC project, the teams of the SECTRANS projects [1] , and INSTASUR [2] , of the European Initiative of CBRN Centers of Excellence, have since their launch developed an e-learning platform in order to ensure the sustainability of the knowledge mobilized during their respective periods of implementation.
Faced with the exceptional situation caused by the spread of SARS-CoV-2 in the world, and thanks to the technical capacities for distance learning developed in 2019 by the INSTASUR and SECTRANS projects, the FRONSEC project implemented its training using e-learning materials. Webinars were thus provided by project experts with the aim of answering questions about distance learning courses and providing tutorials as planned for face-to-face training.
The distance training program set up as part of the FRONSEC project thus offers inter-service training for executives destined to become national trainers for the benefit of customs officers, the police, the gendarmerie and the emergency services. These different training sequences are intended to make participants aware of the specific risks presented by NRBC substances, the means of detecting them, identifying them and protecting themselves from their effects so that they are able to raise awareness among officers at borders.
The courses constituting each of these sequences approach in a progressive way (non-exhaustive list):
-
The basic notions of chemical risks
-
Detection of CBRN substances and their precursors
-
N, R, B and C characteristics and effects
-
The placarding of means of transport, the labeling and packaging of drums and packages
-
Personal protection of border agents
The training takes place in several stages:
An initial self-assessment in 40 questions, followed by free access to the educational sequences of the module over a period of 3 weeks, during which period tutoring is provided via the platform.
This first step is followed by a 5-day webinar which ends with a final evaluation of all participants, a satisfaction questionnaire and the delivery of an individual certificate. A complementary course is aimed at two participants selected by the National Focal Point in order to support them in setting up their first national training courses.
