Detailed Scenarios and Risk Analysis

Scenario 1: Underground Pipeline Maintenance (Poor Ventilation + High Humidity)

At-risk groups: Underground maintenance workers, cable replacement technicians
Heatstroke triggers: Moist heat builds up underground, especially in summer or after rainfall, making it difficult for the body to regulate temperature. This leads to dehydration and heat exhaustion.
Prevention Tips:

• Ensure continuous operation of ventilation equipment
• Rotate workers every 30 minutes
• All personnel must wear CMN heatstroke prevention wristbands before entry
• Encourage hydration and electrolyte replenishment

Scenario 2: Gas Pipeline Inspection (Gas Accumulation + Heat)

At-risk groups: Inspection technicians, safety supervisors
Heatstroke triggers: Residual gas in confined spaces can aggravate heat exposure and oxygen deficiency
Prevention Tips:

• Combine gas detectors with CMN heat stress monitoring wristbands
• Never work on an empty stomach
• If the CMN device triggers red light + vibration + buzzer, evacuate immediately for cooldown

Scenario 3: Urban Drainage System Clearing (Prolonged Heat Exposure)

At-risk groups: Drainage workers, suction truck operators
Heatstroke triggers: Long working hours with limited rest lead to cumulative heat load on the body
Prevention Tips:

• Implement group rotation policies
• Establish a CMN device registration and charging protocol
• Pause non-essential tasks during peak heat hours

Management-Level Policies for Heatstroke Prevention

Policy 1: Pre-approval for Hot Weather Operations

Daily environmental risk assessments should determine whether to proceed with underground work. In extreme heat, operations should be preemptively suspended.

Policy 2: Daily Heat Load Reporting

Based on CMN wearable data, generate daily heat exposure index reports and identify high-risk areas. Integrate the data into BIM safety modules or smart metro construction platforms.

Policy 3: Emergency Response Protocol

If multiple CMN alarms are triggered in the same area, initiate emergency procedures including evacuation and medical evaluation.

CMN Product Integration Recommendations

Advantages of CMN Wearable Devices

• Dual-temperature detection: Combines skin and ambient temperature to estimate core body heat
• 90-second high-frequency sampling: Every 15 seconds; if 3–4 out of 6 readings are abnormal, it triggers an alert
• Triple warning system: Orange light for early warning; red light + vibration + buzzer for critical heat load
• Data visualization: Connects to app to view heat exposure curves and alert history
• Customizable structure: Designed for underground work with waterproof casing options

Deployment Strategy

• Each underground worker wears a CMN wristband + chest clip (compatible with uniforms)
• Supervisors access alert and exposure data via dashboard and can export reports
• Weekly device checks ensure battery status and sensor accuracy

Conclusion

Due to its unique work environment, the urban pipeline industry is prone to heatstroke incidents. Traditional measures are insufficient for rapid response. By deploying CMN smart wearables, management can establish a complete cycle of prevention, alert, and analysis—ensuring the safety and health of frontline workers.
