Review flush plans, pressurisation procedures, and all other relevant documentation to verify compliance with project and safety standards.
Safety & Isolation
Lead and enforce Lockout/Tagout (LOTO) procedures across all fluid and pressure systems on site, including domestic and process water, hydronic systems, pneumatic and hydraulic systems, and oils, refrigerants, and other pressurised media.
Verify physical isolation of all systems before any pressurisation or testing activities are carried out.
Ensure all isolation activities are performed in accordance with applicable safety standards, project specifications, and client requirements.
System Testing & Commissioning Support
Review and manage pipe flushing and cleanliness plans, chemical cleaning activities, and hydrostatic and pneumatic pressure testing programmes.
Ensure all systems are safe, fully compliant, and verified as ready prior to the introduction of fluids or pressure.
Support the safe startup and commissioning of mechanical systems including chillers, dry coolers, CRAH/CRAC water systems, and hydronic distribution networks.
Compliance & Environmental Controls
Ensure all water usage, discharge, and drainage activities meet applicable environmental regulations and comply with project specifications and client standards.
Prevent uncontrolled releases of fluids or pressure that could damage equipment or disrupt site operations.
Coordination & Site Interface
Coordinate daily activities with mechanical contractors, commissioning agents, and owner and client safety teams.
Act as a central point of control for the managed charge and discharge of energy across all relevant systems on site.
Collaborate with all persons involved in a safe system of work, ensuring consistent application of isolation and safety procedures across the project team.
Any other duties or responsibilities that may be assigned to you in your role.
