At CERN, we probe the fundamental structure of particles that make up everything around us. We do so using the world's largest and most complex scientific instruments.

Work is in progress to modernise the fire protection system in the SPS
If you weren’t able to pick up your CERN reflector during the visibility campaign on 14 November, don’t miss the new campaign taking place on 10 December
CERN’s HSE unit is organising a free distribution of reflective tags to help us stay safe on the roads through the dark winter nights
This project will develop a general integrated risk assessment methodology and use it for a number of CERN’s facilities
Winter brings potential health and safety risks, most of which can be easily avoided by taking a few simple precautions
A mock-up fire emergency was organised at two of CERN’s biggest office buildings
LHC tunnel are emergency lights are part of an essential safety system if you ever need to evacuate
CERN is modernising its safety policy and organisational structure in matters of Safety
The documents published on 29 September 2014 on the HSE website, together replace the document SAPOCO 42 as well as Safety Codes A1, A5, A9, A1
New “traffic-calming” measures have been set up near Restaurant 2, to encourage drivers to slow down to safe speeds
When night falls over CERN, a team of X-ray experts go underground to perform tests on the Large Hadron Collider
On 28 April each year, the International Labour Organization and the World Health Organization organise a World Day for Safety and Health at Work
