· Conduct field verification of all LOTO procedures to ensure accuracy, compliance, and site applicability.
· Maintain and manage all LOTO devices, tags, hasps, and lockout kits across the facility.
· Support commissioning and start-up teams to ensure strict adherence to hazardous energy control procedures at all times.
· Coordinate COHE/LOTO requirements with the main contractor, Emerson Automation, vendor teams, and Utilities.
· Serve as the site SME for hazardous energy control, providing technical guidance and oversight to all personnel.
· Maintain up-to-date COHE documentation aligned with site EHS requirements and the Permit to Work system.

· Ensure all activities are executed in compliance with applicable safety legislation and site-specific procedures.
