The promise of the data center boom will not be realized if safety and workforce development do not keep pace.

      PwC predicts that investment in U.S. data centers will reach $118.4 billion by 2027, marking a 116% increase. Deloitte reports a 64% rise in data center job postings compared to a mere 4% across the broader economy, with electrical technician postings soaring by 180%. Patrick Doyle highlights that the sector is attracting workers from the restaurant and grocery sectors into high-risk construction roles without sufficient mentoring or a safety-focused culture. He emphasizes the need for personalized mentoring for new employees, discussions on safety before each job, and enforcement of stop-work authority.

      The success of the data center expansion will depend not only on the infrastructure built but also on the safety of the workers involved. With significant opportunities arise a rush for investments, market dominance, and leadership in the industry. This intensifies timelines, accelerates hiring processes, and can lead to safety being viewed as an impediment. From my experience in high-risk environments, this oversight can lead to disastrous consequences. Skimping on safety can harm individuals, halt projects, and squander the very capital that is being fiercely protected.

      The magnitude of the current development phase makes the associated risks impossible to overlook. PwC anticipates a dramatic rise in U.S. investment for data center infrastructure, increasing from $53.2 billion in 2024 to $118.4 billion by 2027. This is not a gradual increase; it involves a substantial amount of complex work that is being undertaken within a condensed timeframe.

      The workforce is similarly being stretched. Deloitte discovered that job postings in key roles within data centers surged by 64% from 2023 to 2025, contrasting sharply with the broader economic growth of only 4%. Meanwhile, postings for electrical technicians rose by over 180%. In Deloitte’s findings, 63% of data center executives cited a lack of skilled labor as their primary talent challenge. While there are real opportunities for workers, the urgency to plug workforce gaps before sufficient preparation is also evident.

      I've observed individuals transition from restaurants, grocery stores, and other fields into construction and energy positions. Although their experiences are valuable, the risks they face are different. For instance, someone unfamiliar with a hand drill may not know how to react if it jams. A new night shift worker might arrive fatigued due to their body not yet adjusting. Working outdoors presents challenges like heat, cold, and hydration, all of which can impact decision-making.

      The issue is not with new recruits; rather, employers must ensure they are well-prepared. A certification obtained in a day or two does not equate to true competence, and an orientation session isn't a substitute for supervised experience. When demand outstrips the availability of qualified candidates, employers may opt for shorter training periods, accept dubious qualifications, or assume that new hires will learn on the job. Such assumptions can jeopardize the safety of everyone on complex data center sites.

      The solution starts with structured onboarding. I advocate for a short-service employee program where each new worker is paired with a seasoned journeyman or senior employee, ideally in a one-on-one format for high-risk tasks. The mentor monitors the new employee's progress and helps them grasp both the responsibilities and the site dynamics. This program could last 90 days, six months, or longer; the key is demonstrating competence.

      Preparation should also take place prior to each task. Job safety and pre-job risk assessments should be interactive discussions rather than mere compliance forms. Teams ought to discuss what will occur, how they will execute the work, what variables might change, and when they should cease work. Practicing the task helps individuals visualize it before equipment, machinery, and variable conditions come into play.

      Crucially, workers must understand that they will be supported if they decide to halt work for safety reasons. Many hesitate due to fears of retaliation or assumptions they will be blamed for not meeting a deadline. Leaders shape organizational culture based on what they reward. Reporting hazards, asking questions, or refusing to undertake unsafe tasks should be recognized as responsible actions. If employees hear “see something, say something” during orientation but witness supervisors punishing delays in practice, the actual policy becomes evident.

      The data center sector has a unique opportunity. Its workforce is coming from various trades and backgrounds, allowing the industry to define safe practices as the standard from the outset. Achieving this goes beyond merely hosting seminars; it necessitates skilled supervisors, manageable workloads, ongoing coaching, and steadfast expectations even when deadlines are tight.

      Some executives might perceive these measures as additional time and cost burdens. However, the business rationale indicates otherwise. EY highlights that shortfalls in skilled labor and specialized contractors are already driving up expenses and prolonging project timelines, while construction delays can incur substantial financial penalties. An incident brings a series of repercussions: investigations, damaged machinery, lost productivity, absence of qualified personnel, legal implications, and potentially a shutdown. A rushed choice made to save time could jeopardize the entire project timeline.
