Detailed Scenario Analysis

TBM (Tunnel Boring Machine) Front Shield Area

The TBM head generates additional heat and operates in highly humid, poorly ventilated spaces.

Heat Stroke Risk Factors:

• Mechanical heat + groundwater infiltration.
• Fully enclosed PPE reduces heat dissipation.

Prevention Measures:

• Activate ventilation and dehumidifiers prior to entry.
• Use CMN wearables to collect core data for Heat Stroke Prevention for Subway Development.
• Enforce 25/10 work-rest cycles, and prohibit solo work.

Foundation Pit and Civil Structure

Deep excavation zones collect and trap hot air due to limited airflow and vertical walls.

Heat Stroke Risk Factors:

• Heat trap effect: Air stagnation at pit base.
• Distant cooling areas: Workers avoid leaving zone for rest.

Prevention Measures:

• Install fixed sensors and sync with CMN wearable platform for heat stroke prevention for subway development.
• Supply personal cooling kits and electrolyte sachets.
• Schedule micro-breaks at the work point.

MEP Installation and Interior Finishing

The MEP and finishing phases concentrate workers and machinery in poorly ventilated areas, creating unexpected heat spikes.

Heat Stroke Risk Factors:

• Enclosed stations with excessive lighting and equipment.
• Compartmentalized zones block airflow.

Prevention Measures:

• Deploy CMN wearable checkpoints across zones for heat stroke prevention for subway development.
• Provide portable cooling devices per crew.
• Adjust workflows based on wearable alert data.

Targeted Heat Stroke Prevention Measures

Shift Structure and Rhythm

Divide shifts using a 25–10–25 work-rest-cool cycle under Heat Stroke Prevention for Subway Development standards.

Hydration and Salt Balance

Provide 3000ml/day electrolyte drinks to all staff as part of heat stroke prevention for subway development plans.

Real-Time Wearable-Based Alerts

CMN wearable samples temperature every 15 seconds, using thermal differential algorithms for timely alerts during heat stroke prevention for subway development.

Advantages of CMN Smart Wearable Device

Engineered for Underground Environments

• Moisture-resistant, dirt-proof, and shockproof design—suitable for all phases including tunneling, foundation pits, and interior finishing.

• Operates independently of network signals, with on-device heatstroke detection and alert capabilities.

Multi-Level Smart Alert System

• Orange Light: Alerts for High-Temperature Areas
  Red Light + Beep + Vibration: Strong Alert Automatically Triggered After Multiple Abnormal Temperature Readings
• Supports Data Upload to Backend for Generating Heat Risk Maps of Work Areas

Centralized Risk Management Integration

• Generates Daily Work Heat Index Reports and Statistics on High-Frequency Alert Zones
• Data Can Be Integrated into BIM Safety Modules or Smart Subway Construction Platforms

Integrated Strategy for Demolition Heat Safety

1. Based on CMN Device Alerts, Establish a Real-Time Display Mechanism for the “Underground Heat Load Map”

2. Require Team Leaders to Summarize Each Member’s Daily Heat Exposure Duration as a Reference for Next-Day Scheduling

3. Incorporate Heat Stroke Prevention for Subway Development into the General Contractor’s Safety Evaluation System

Conclusion

Subway development sites pose significant thermal stress risks. By analyzing risk stages, deploying structured work-rest protocols, and using CMN’s high-frequency thermal monitoring system, Heat Stroke Prevention for Subway Development transitions from policy to practical implementation.
