Supporting OSHA Heat Safety Requirements with Nix Pro

Monitor hydration status, track heat risk, document interventions, and support heat illness prevention programs through real-time sweat data
Download PDF: Supporting OSHA Heat Safety Requirements with Real-Time Hydration Monitoring

Nix Pro delivers real-time insights and alerts on individual hydration status in a single dashboard view, allowing for proactive intervention to prevent heat-related illnesses and to help organizations meet evolving OSHA heat safety requirements.

The platform delivers personalized hydration data in real time highlighting which subjects may be at risk or need a safety check. The platform performs trend and correlation analysis across different environments, exertion types and subgroups to identify patterns and drive the predictive risk-assessment model for future shifts based on the forecasted conditions.

Nix Pro helps organizations:

  • Reduce heat-related risk
  • Improve worker readiness and productivity
  • Support OSHA compliance efforts
  • Create defensible documentation
  • Build individualized heat safety programs at scale

The platform pairs with the  Nix Hydration Biosensor, a lightweight electronic pod that clips onto a single-use sweat patch and sticks to the front of the bicep. Once a subject begins to sweat, real-time hydration data will be sent to Nix Pro. 

New OSHA Heat Regulations Are Changing Employer Responsibilities

Heat-related illness can occur in nearly any environment where workers perform moderate-to-high physical activity, wear PPE, or operate in hot and humid conditions. Under OSHA’s National Emphasis Program (NEP) and evolving federal heat safety standards, employers are increasingly expected to:


  • Identify heat hazards and monitor workers at risk
  • Implement prevention plans
  • Document interventions and training
  • Uphold reasonable safety measures during inspections
OSHA Requirement * Nix Pro Solution
Heat Hazard Identification
Evaluate environmental conditions, workload, PPE, and individual worker risk factors.
Individual Insights
Measures individual sweat losses and identifies high-risk workers through their personal physiology.
Heat Illness Prevention Planning (HIPP)
Implement structured heat illness prevention strategies and documented planning.
Predictive Calculator & Hydration Suggestions
Predictive hydration planning workflows based on individual subject data and prevention recommendations.
Hydration & Electrolyte Practices
Provide adequate hydration and electrolyte replacement during heavy sweating.
Custom Drink Calculator & Sweat Composition

Hear From Nix Pro Users:

"We had a stretch of unusually hot days last summer where the heat index jumped above 100°F on one of our job sites. Normally we would have just increased water breaks and kept going, but the Nix data showed one of our workers losing sodium at nearly double the rate of the rest of the crew. We were able to adjust his hydration plan immediately. That was the moment we realized how valuable it was to actually see what was happening individually."

William Patrick, Massachusetts Dept. of Transportation

"Monitoring the environment only gets you so far. It’s far more powerful to know how the worker is responding physiologically, and get notifications when to take actionable steps to keep them safe and properly hydrated."

Anthony Benedictis, CATC, CSCS, 211 Performance Therapy, a Tactical Athlete training organization working with North America’s top Fire Departments

"Before using Nix Pro, our heat safety program was largely based on environmental conditions and general hydration guidance. Now we can proactively identify risk, practice early intervention, provide personalized hydration strategies, track acclimatization, and have our whole practice documented for when inspections inevitably pop up."

Derek Lawson, Safety & Field Operations Manager, Frontier Peak Energy Group
