Measure, analyze, and improve performance to meet business objectives. Establish and govern key metrics (e.g., OSHA injury rate, near misses, safety observations, and EM performance) and use leading indicators to anticipate and mitigate risks to employee health and safety.
• Develop and maintain deep technical expertise in radiopharmaceutical manufacturing (RLT, PET and isotope products), including radioactive material handling and controls, radiochemistry/radiosynthesis, automated synthesis platforms, in-process controls, and analytical/quality procedures. Ensure technical knowledge is translated into robust procedures, training, and standardized ways of working to prevent health and safety risks and radiation exposure.
• Create and continuously improve the site EHS management system and compliance programs, including written programs, procedures, inspections, and governance routines that drive consistent execution.
