Who’s responsible for what
You
Every individual is responsible for their own safety and for not endangering others – whatever your role, contract type, or however long you’re on site.
If a situation is unsafe, stop the activity, alert others where safe, and seek assistance. Take action only within your competence.

Safety Officers
RSO, CSO, FGSO, LSO, VSO, TSO and the
LEXGLIMOS team sit on the advisory line – they
support, advise and monitor Safety within their assigned mandates and perform the tasks specified in their written appointments and applicable CERN rules. Their appointment does not transfer the Safety responsibilities of management or individuals.
Line management
Supervisors have Safety responsibilities matching their functions.
In matters of Safety, CMS is represented at CERN by the Technical Coordinator.
Under the oversight of the Technical Coordinator, the Collaborating Institutions participating in CMS experiment shall each be responsible for Safety within the Large Experiment, in accordance with the CERN Safety Policy, the CERN Safety Rules and best practices, including for the Safety of the Installations, activities and projects under its responsibility.
TC responsible for the infrastructure and personnel.
Collaborating Institutions responsible for their personnel.
What this means day to day
Check out the CERN Safety Fundamentals
Safety First, Safety Always.
Report any issues
Report hazards promptly to your supervisor and the relevant Safety Officer (e.g. TSO, LEXGLIMOS).
Report all safety incidents, including unsafe situations and near misses, using the EDH Incident Declaration form within 24 hours of their occurrence or discovery, whichever is earlier.
If immediate action is required, promptly contact the appropriate CERN service. For an emergency, call +41 22 767 4444, or 74444 from a CERN phone.
Use the Service Desk for non-emergency service requests; it does not replace the incident declaration.
Contribute to site cleanliness
Keeping walkways clear, sorting waste
correctly, and tidying up after an
activity is part of running any activity
safely, official CMS guidance included.
See Waste Sorting Procedures.
Verify your trainings and qualifications
Do not perform any actions you are not trained and authorized for.
Don’t assume your safety courses are still valid, check your course history and expiry dates regularly and follow the reminders from the Safety Training Center. Make sure you hold everything required for the zone and activity you’re working in before you start. See Training Requirements by Activity and Role.
Check your equipment
Make sure your equipment is suitable for the actions to be performed.
Give your PPE a visual check before each use – helmet, harness, self-rescue mask -and make sure anything needing periodic inspection (Class 3 PPE, at minimum every 12 months) is controlled – follow the applicable equipment-specific inspection, maintenance and expiry requirements.
If something looks worn, damaged, or expired, don’t use it – report it and arrange replacement or inspection.
See Personal Protective Equipment.
Follow the Safety Rules
CERN’s Safety Regulations – Safety Rules, General Safety Instructions, Safety Codes, and Specific Safety Instructions – that remain in force. CERN establishes its own Safety Rules, taking account of relevant national and international requirements. Where CERN has not established Safety Rules, the relevant Host State laws and regulations apply on a territorial basis.

Stay up to date
Participate in information meetings, read communications from the CMS Safety Office, and check the CMS Safety Website for anything new. If your activity or work area changes, check whether your risk assessment and training still cover it.
