The evolution of risks, the transformation of industries and the development of urbanism around activity zones significantly increase the number of structures concerned by the risks of criminal or accidental explosions.

Explosion, complex and regulated risks

An explosion can have dramatic consequences on the integrity of your structures. They can cause severe damage or even destroy your structures. In addition, they endanger employees, local residents and can have an impact on the environment.

The risks are known and most often anticipated. However, establishing a study taking into account all the ins and outs remains a complex subject. This is due to the technical complexity and the regulations in force.
