Heat Stress Monitors

Heat affects decision-making, endurance, and recovery during emergency operations. For fire service, hazmat, USAR, and tactical teams, heat stress escalates quickly due to turnout gear, chemical suits, body armor, and high-intensity tasks. TSI heat stress monitors provide rapid, reliable WBGT and related indices to help command staff manage exposure on the apron, at training grounds, and on incident scenes.

What Matters for Emergency Response

• Rapid Deployment: Quick startup and intuitive menus help crews capture conditions before assignment and throughout operations.
• Rugged Design: Durable housings and protected sensors hold up to transport, staging, and field use.
• Clear Alerts: Audible and visual cues help crews adjust rotations and hydration strategies when conditions change.
• Glove-Friendly Operation: Large displays and simple controls support use in PPE.
• Data You Can Use: Logging and wireless options help departments document conditions during live burns, drills, and critical incidents.

Operational Use Cases

• Fireground Rehab: Monitor WBGT in rehab to help guide rest duration, cooling approaches, and return-to-duty decisions.
• Hazmat and CBRN: Track environmental load for teams in encapsulating suits and integrate readings into time-in-suit plans.
• Law Enforcement/Tactical: Measure heat during training days, range operations, and prolonged deployments in urban heat.
• Training Academies: Benchmark conditions across evolutions to help instructors pace workload and manage cadet performance.

Program Alignment and Guidance
TSI heat stress monitors are designed to support alignment with ACGIH Threshold Limit Values for heat stress and ISO 7243 guidance for WBGT. They help departments build a consistent process around heat-related SOPs, from pre-incident checks and staging to rehab and demobilization.

Key Features to Consider

• WBGT (indoor/outdoor) with options to display globe, wet bulb, and dry bulb temperatures
• User-set thresholds with audible/visual alerts
• On-board logging and reporting to support after-action reviews
• Wireless connectivity for remote viewing and documentation
• Tripod and carry options for flexible placement in rehab or staging
• Calibration and service support to help maintain measurement confidence

Implementation Tips

• Place a monitor in staging and rehab; add a second unit at the work area for gradient awareness.
• Establish thresholds aligned with department policy and regional climate.
• Log readings at defined intervals to support after-action analysis and training improvements.
• Use alerts to cue rotations and hydration checks during extended operations.

From live fire to summer events and disaster response, TSI heat stress monitors help command staff make timely, informed decisions that support crew readiness and recovery. Build your heat monitoring standard operating practice with tools designed for the realities of emergency response.
