The document summarizes the duties and responsibilities of a senior lab chemist at an ethylene, utility, and environmental laboratory. Key responsibilities included supervising a shift team, ensuring correct and timely reporting of test results to customers, maintaining quality standards and accreditation, conducting safety audits, and being an expert in a wide range of analytical testing methods for samples like condensates, naphthas, gases, and amine solutions. Maintaining ISO/IEC 17025 accreditation and safety standards were priorities.
