Safe Handoffs: Protecting Data Center Crews From Construction Through Commissioning

As construction overlaps with commissioning, safety leaders need to verify qualifications and assign who communicates each change.

U.S. data center construction spending reached an annual rate of $85 billion in August 2026. As major projects like Stargate expand, worker safety concerns underscore the need to protect crews throughout the buildout.

Safety responsibilities span contractors, teams and project phases, particularly when construction overlaps with commissioning. Clear accountability, ongoing training and timely communication about changing risks are essential to protecting every worker on site.

Preparing Frontline Workers for Data Center Safety Risks

Safety standards set the baseline, but rules alone can't keep workers safe when conditions on site keep changing. The 2027 edition of NFPA 70E reinforces the importance of documented electrical safety training and clarifies that workers may be qualified for certain equipment and tasks but not others. For safety leaders, that means ensuring workers have the necessary qualifications and understand the risks associated with their assignments as data center construction moves into testing and commissioning.

In data center construction, electrical crews may begin testing switchgear while mechanical contractors are still installing cooling equipment nearby. Workers must navigate hazards ranging from electrical shock and burns to injuries from moving equipment or falling materials, often as access restrictions and safety procedures change.

The pressure to hire qualified workers adds another challenge. Fifty-eight percent of contractors working on data center projects said those projects have increased competition for skilled workers. Another 50% of contractors said available candidates lack the skills, certifications or licenses the work requires. These pressures make verifying qualifications and preparing crews for site-specific hazards especially important.

With candidates scarce and projects moving quickly, training cannot stop at onboarding. Crews need task-specific instruction alongside clear, timely updates about equipment status, restricted areas and changes to safety procedures.

Recheck the Risk When Work Changes Hands

As data centers move into commissioning, gaps in safety communication can leave crews working from outdated or incomplete information. During this phase, installed power and cooling systems are tested to confirm they perform as designed before the facility is handed over to operations. Construction may still be underway, so one team's testing can change the precautions other crews need to take.

Planning should anticipate those transitions and clearly assign responsibility for communicating changes as work passes between installation, commissioning and operations teams. Each handoff should confirm what has changed, which crews are affected and whether those crews understand the precautions required.

Before switchgear testing or energization, crews working in the area need to know the equipment status and any new access restrictions. For example, if a room is closed for electrical testing, the handoff should identify who will notify the next shift and confirm access restrictions remain in place. Completed permits cannot make up for that missed communication.

Use Connected Workflows to Strengthen Frontline Safety

Keeping safety information current also depends on observations from the people closest to the work. Frontline workers often spot the first warning, whether a barrier has shifted, materials are unstable or a shortcut has become routine. For data center operators and safety managers, the challenge is making sure those observations reach the right teams and lead to action. Connected frontline workflows and AI can help:

• Simplify reporting. Workers can quickly report hazards using a mobile form, photo or voice note. AI-assisted prompts can help capture missing details so safety teams have the information needed to respond.
• Identify and communicate risks. AI can help flag potentially serious incidents (PSIs), identify recurring hazards and highlight patterns across work areas. Connected workflows can route those findings to the responsible teams and share relevant safety updates across contractors and shifts.
• Make corrective actions visible. A site-wide reporting system should assign responsibility, track progress and communicate changes to the affected crews. Workers should know what was addressed and what precautions they need to take.

AI can help managers prioritize concerns and coordinate responses, but safety leaders remain responsible for verifying that corrective actions work and communicating the results to the affected crews.

As the data center buildout expands, so does the need to coordinate safety across contractors, shifts and project phases. The practices set during the build carry into operations long after construction ends.

The buildout is setting the pace. Operators decide whether safety information keeps up with it.
