  • Fire safety at CERN: the importance of evacuating safely

    CERN’s vast site hosts a variety of buildings and installations, as well as diverse groups of people, from seasoned personnel to first-time visitors. Fire safety measures are implemented to protect this diverse population, but also CERN’s costly infrastructure and the environment. Ensuring safe evacuation is a priority in this context, with building layouts designed to

    Pressure equipment safety: your responsibility, our priority

    Safety is everyone’s responsibility. At CERN, pressure equipment such as vessels, piping and safety accessories is essential for both industrial and experimental activities. However, these systems also pose risks due to the energy they contain and the chemical hazards posed by their contents. In the interests of the safety of all personnel and installations, it
