Heat Stress Monitors

Thermal stress is a daily variable in power generation and mining. Boiler and turbine areas add radiant load, underground headings limit airflow, and outage work amplifies both heat and metabolic demand. TSI heat stress monitors provide the WBGT and component temperatures needed to help supervisors manage exposure in real time and plan work more effectively.

Why They Fit Power and Mining

• Rugged and Practical: Durable housings and protected sensors handle vibration, dust, and transport between units or levels.
• Fast to Deploy: Quick stabilization captures conditions during pre-job briefs and throughout tasks.
• Clear, Actionable Alerts: Audible and visual cues help teams adapt rotations, cooling, and staging when conditions shift.
• Long Runtime: Battery capacity supports extended maintenance windows and underground shifts.

Operational Applications

• Power Generation: Monitor WBGT on boiler decks, near condensers, and in turbine halls during peak demand and outages.
• Surface Mining: Track heat at the mill, crusher, and pit operations with mobile placement and rapid checks.
• Underground Mining: Measure conditions in headings and refuge areas to support ventilation plans and task sequencing.
• Contractors and Turnarounds: Provide consistent monitoring for multi-employer sites during shutdowns and capital projects.

Program Alignment
TSI heat stress monitors are designed to support ACGIH TLVs and ISO 7243-based procedures while complementing OSHA heat illness prevention guidance. Logging and wireless access help sites coordinate across shifts and contractors, including documentation for job safety analyses and after-action reviews.

Key Features to Consider

• WBGT (indoor/outdoor), globe, wet bulb, and dry bulb measurements
• User-defined thresholds with audible/visual alerts
• On-board logging with exportable datasets for reporting and audits
• Wireless connectivity for centralized viewing and shift handoffs
• Mounting and transport accessories for fixed and mobile use
• Calibration and service programs to help maintain measurement confidence

Implementation Tips

• Place monitors where workers experience the highest radiant load — not just at ambient locations.
• Use tiered alerts to prompt hydration checks, shorter cycles, and cooling breaks during outages or heat waves.
• Trend WBGT against task schedules to identify better time windows for high-heat work.
• Incorporate readings into ventilation planning and contractor pre-job briefings.

By integrating TSI heat stress monitors into daily checks and outage planning, power plants and mines gain practical, defensible data that helps teams act sooner and organize work smarter under hot conditions.
