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.

Exchanges of a strategic nature cover:
weapons of mass destruction (WMD),
conventional weapons,
related materials likely to be used:
for the purposes of their design,
of their development,
of their manufacture
or their use,
and their vectors.
The United Nations Security Council Resolution 1540 , adopted in 2004 with a view to combating the trafficking and smuggling of WMD and related materials, emphasizes the need to put in place and institute appropriate and effective mechanisms for the control of export, transit and transhipment of these products. Although it is essential to fight against the trafficking of goods of a strategic nature and customs constitute the first and last line of defense at the national level, the mission which is devolved to customs administrations in this context does not remain less particularly difficult. The WCO has taken a number of initiatives to help Customs administrations meet this challenge.
In 2016, the Ad Hoc Project on ACES became a long-term program. This change in status has broadened its scope and the program is now structured around the following 6 main axes:
Organizing train-the-trainer workshops to accredit experts
The provision of training dedicated to ACES, within the framework of the WCO Course Program
The implementation of the STRATComm communication platform 24 hours a day, 7 days a week, 365 days a year
Organizing other fraud enforcement operations
The intensification of awareness-raising and information activities for businesses
The development of a reporting system for ACES-related seizures in CEN
The ACES Program is a continuation of the ACES Project, launched in 2013. It builds on the achievements of the Project, which include:
The organization of awareness seminars
The development of a complete training course on ACES specially designed for customs
The coordination of a worldwide fraud repression operation in the field of ACES (Cosmo).
As part of the ACES Project, the WCO has developed a Implementation guide detailed information on ACES with a view to assisting Members in their efforts to design, revise and implement their own control systems and procedures for this type of goods, and to provide, at the same time, a framework for reference for the training course.
