On 03 September, 2026, CERN announced updates to its Safety Rules. The revised regulations were published on the CERN website, covering various aspects of safety. Safety Regulation SR-M, the "Mechanical Equipment" guideline, was revised (EDMS 875606). General Safety Instruction GSI-M-2, dealing with "Pressure Equipment," was also updated (EDMS 875610).
Additionally, GSI-M-4, addressing "Cryogenic Equipment," underwent revisions (EDMS 1327191). The Cern Community can access all these Safety Rules at http://www.cern.ch/safety-rules. Questions about the updated rules should be directed to Safety-Rules.Secretariat@cern.ch. These regulations apply to all individuals under the Director General's authority.
The updates were prompted by the introduction of a new risk-based inspection concept, which replaces the Major Safety Implication (MSI) approach with a standard authorisation system for deviations from Safety Rules' provisions, contingent on satisfactory risk assessment and mitigation.
