The use of beryllium and its alloys in high-energy physics applications at CERN requires a robust and institution-specific regulatory approach due to the material's toxicity and the stringent cleanliness constraints associated with accelerator components. This article presents the development and implementation of a dedicated internal framework formalized through Safety Guideline SG-C-0-0-6, reaffirming mandatory requirements for risk assessment, exposure prevention, contamination control, waste management, and medical surveillance related to beryllium activities at CERN.

SG-C-0-0-6 provides detailed instructions for the implementation of existing CERN Safety Rules which define clear roles and responsibilities for line management, safety officers, supervisors, and operational personnel. It introduces a graded risk-based approach covering design of engineering controls at source, organizational measures and access restrictions, air and surface monitoring strategies and qualification of work areas. The guideline integrates occupational exposure limits and acceptable surface contamination levels with operational constraints specific to CERN's technical infrastructure.

To ensure effective implementation, a structured safety training programme was developed and deployed. The programme addresses supervisors, persons working directly with beryllium and its alloys, and personnel handling beryllium-containing components. Training combines regulatory requirements, toxicological fundamentals, safe work practices, emergency response, and hands-on contamination control exercises.

The article discusses the risk-based methodology underpinning SG-C-0-0-6 and the challenges encountered during institutional deployment,
