The ATEX standard thus governs the protection of workers in these potentially dangerous areas at European level. In particular, it categorizes each area according to its degree of risk, and imposes safety standards on it, such as the use of specific equipment, which cannot become a source of ignition.

Some environments are more sensitive than others, here are examples of places at risk:
– Chemical plants
– Refineries and service stations
– Airports
– Cement factories
– Food factories
- Nuclear center
