Heatwave alert: high fire risk across the CERN site
The current heatwave and dry conditions have significantly increased the risk of fire across the CERN site. Dry vegetation can ignite easily, threatening people, buildings and operations. Although a recent fire near the high-voltage substation on the Prévessin site was safely managed, it highlighted the potential danger. CERN’s Green Spaces team is taking measures to

Stay safe on the roads during the G7: 12–18 June 2026
As we navigate the exceptional access conditions for the G7 Summit (12–18 June), remember that road safety is a shared responsibility – whether you’re driving, cycling or walking. Increased traffic, border controls and potential diversions mean that your vigilance is more important than ever. Key reminders Let’s all do our part to keep CERN’s community safe during this

Ready for Heatwaves
As spring gives way to summer, we must stay prepared for whatever the season brings – especially when it comes to periods of intense heat. MeteoSwiss declares a heatwave when average temperatures exceed 25°C for at least three consecutive days. To help protect personnel during such events, CERN introduced its dedicated Heatwave Action Plan in 2023. This

IMPACT undergoes a transformation: new interface launched for LS3 readiness
Work to improve IMPACT, CERN’s Intervention Management Planning and Coordination Tool, has reached a major milestone. After several years of upgrade work and extensive user consultation, the “IMPACT declaration” (Activity feature) is now being launched to help support the needs of the CERN community during the third long shutdown (LS3). IMPACT is a critical web application used by a

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

NIRMA on the move: mapping electromagnetic environments at CERN
Over the coming weeks, you may notice a vehicle equipped with antennas driving slowly on the CERN roads. This is part of the Non-Ionising Radiation Mapping and Assessment (NIRMA) project. The vehicle is equipped with the TURTLE (Top-mounted Unit for NIR Time-averaged Field Level Evaluation), a mobile unit dedicated to measuring electromagnetic fields in the

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
