Lead safety: Own shift safety practices—spill management/reporting, confined space adherence, Class I, Div I protocols, and PPE—while conducting timely investigations, root cause analyses, and meaningful safety kickoffs to minimize recordables and LTAs. Conduct internal audits (receipts, proofing, loss reporting, system transactions, calibrations), support external audits, and ensure accurate inventories, calibrations, 122 and 137 recordkeeping, and timely variance initiation.
