THE CHALLENGE

ECS needed to strengthen safety execution without slowing down the field

Engineered Cooling Services (ECS) provides HVAC, MEP, and facilities services to commercial, industrial, and mission-critical customers across the Southeast and Gulf Coast. In high-risk industrial environments, safety isn't optional — it's a contract requirement. ECS's Total Recordable Incident Rate (TRIR) had reached 3.06 — above the industry red line that can disqualify contractors from industrial job sites. Paper-based Job Safety Analyses (JSAs) were rarely used and difficult to track. Technicians had no consistent way to escalate safety concerns in the field, and management had limited real-time visibility into what was happening on the job site.

APPROACH

XOi embedded safety into every technician's workflow

ECS used XOi to digitize JSAs and embed them into technician workflows, making safety documentation a routine part of every job rather than an afterthought. Inspired by examples from other teams, ECS also introduced safety prompts and enabled technicians to flag hazards via video — triggering stop-work protocols and immediate manager alerts. These tools reinforced safety awareness in the field and standardized compliance across teams.

IMPLEMENTATION

ECS's approach focused on making safety a workflow habit, not a checkbox

By embedding safety documentation into the same platform technicians already used for every job, ECS removed the friction that made paper JSAs easy to skip. Safety became the default, not the exception.

TRIR cut by over 50%

Total Recordable Incident Rate dropped from 3.06 to 1.40 in one year, and held at an average of 1.38 over the next four years.

270+ hazards documented

270+ job site safety concerns were flagged by technicians using XOi, each triggering automated alerts to management for immediate response.

THE IMPACT

What changed when safety became part of the workflow

ECS cut their TRIR by more than 50% in a single year and held that improvement for four years running — protecting their technicians, preserving their ability to win industrial contracts, and building a safety culture backed by real-time documentation and accountability.

• TRIR reduced by over 50%, from 3.06 to 1.40
• Average TRIR held steady at 1.38 over the following four years
• 2.3x digital JSA usage increased
• 270+ jobsite safety concerns documented
• 99% of all technician leads come through XOi (up from 40%)
• 15% total tech generated lead volume increased in 90 days

"With XOi, safety became part of the workflow—not an afterthought. That shift helped lower our TRIR, protect our technicians and our ability to serve industrial clients."
