Energy Marshal

SUMMARY

Ajax Building Company, part of the STO Building Group, is seeking an experienced, hands-on Energy Marshal to oversee the safe execution of energization and energy-isolation activities on mission critical data center projects. This role is responsible for administering the site’s energy-control program, managing Lockout/Tagout (LOTO) procedures, auditing field practices, and providing expert guidance from pre-energization through commissioning, project completion, and turnover.

The ideal candidate will bring a strong construction-safety background, technical knowledge of electrical and other hazardous energy systems, and direct experience supporting mission critical or data center construction. The Energy Marshal serves as the project’s subject matter expert on energy isolation and has independent authority to stop work when unsafe conditions or practices are identified.

The Energy Marshal reports to and is directly accountable to the General Superintendent.

ESSENTIAL FUNCTIONS

• Manage energy-control and commissioning activities from pre-energization through project completion and turnover.
• Develop, administer, and enforce the site-specific Lockout/Tagout (LOTO) program.

• Conduct pre-energization inspections and verify that systems, documentation, and safety controls are complete before energization.
• Ensure compliance with established safe-work practices during energization, de-energization, testing, and isolation activities.
• Review and verify commissioning plans, energization plans, quality reports, and supporting documentation.
• Review, approve, and audit energy-isolation procedures for safety, accuracy, and compliance with project standards.
• Serve as the subject matter expert for energy isolation, providing technical guidance and support to project teams, trade partners, and other stakeholders.
• Attend daily and weekly High-Risk Activity (HRA) and Job Hazard Analysis (JHA) meetings, providing procedural support for work involving energy isolation.
• Interpret one-line diagrams, system drawings, and equipment redundancies to ensure LOTO procedures are properly designed and implemented.
• Provide guidance regarding the control of multiple energy sources, with particular emphasis on electrical systems.
• Verify the safe installation and energization of electrical equipment across multiple voltages, including AC and DC systems.
• Audit field practices against established procedures, written standards, and applicable safety requirements.
• Partner with project teams to identify risks, resolve issues, and implement continuous-improvement strategies.
• Clearly communicate technical requirements and energy-related concepts to both technical and nontechnical audiences.
• Exercise independent stop-work authority whenever unsafe energy-isolation or energization practices are identified.
Participate in weekly project safety meetings and other required planning or coordination meetings.
