The MEP Superintendent is responsible for ensuring the safe isolation, control, draining, flushing, and management of all fluid and pressure systems (water, air, oil, refrigerant, and other piping systems) during data center construction, pre-commissioning, flushing, hydrostatic testing, and startup activities. This critical safety role prevents accidental release of fluids or pressure, supports safe work practices on mechanical systems, and protects personnel and equipment during high-risk phases of the project. 

Key Responsibilities 

• Oversee and enforce Lockout/Tagout (LOTO) and isolation procedures for all fluid, pneumatic, hydraulic, and pressure systems 

• Verify and approve isolation points (valves, blinds, blanks, drains, vents) before work begins on piping, pumps, chillers, cooling towers, or related systems 

• Manage piping flush plans, chemical cleaning, hydrostatic/pneumatic pressure testing, and system draining/venting activities 

• Coordinate with mechanical, piping, and commissioning teams to ensure proper isolation, depressurization, and safe reintroduction of fluids or pressure 

• Conduct pre-work safety reviews and hazard assessments for activities involving water, air, refrigerant, oil, or other process fluids 

• Perform regular audits and inspections of isolation devices, tags, blinds, and control procedures 

• Maintain accurate records of all isolations, permits, flush plans, test results, and clearances 

• Serve as the single point of control for re-pressurizing or reintroducing fluids into systems after work is completed and verified 

• Stop any unsafe work related to fluid or pressure systems immediately 

• Train and coach site personnel on fluid isolation, flushing best practices, and hazardous energy control for mechanical systems 

• Participate in incident investigations involving fluid release, pressure, or piping-related events 

• Ensure compliance with OSHA Control of Hazardous Energy (LOTO), company safety standards, and relevant mechanical/piping codes
