• Coordinate ALARP reviews with process owners, engineering, management, and global experts; document rationale, approvals, risk-reduction commitments.
• Partner with process owners and engineering to maintain process descriptions, safe operating limits, and P&IDs; verify safeguards against installed conditions.
• Support capital projects from design through turnover, including PHA planning, design and change reviews, and startup-critical action closure.
