Case Study 1: Wet Tanning Zone

Risk Characteristics

During tanning, hides are immersed in chemical solutions for hours. Workers operate in extremely humid conditions, wearing rubber suits and gloves, which hinder sweat evaporation and body cooling.

High-Risk Workers

Chemical handlers, tanning mixers, new entry operators.

Heat Stress Triggers

• Relative humidity often exceeds 70%—sweat does not evaporate effectively.
• Protective gear retains heat and restricts airflow.
• Prolonged exposure to chemical odors and steam leads to fatigue.

CMN Solution

With CMN heat stress monitoring wristbands, workers receive real-time alerts when abnormal readings are detected over 90 seconds. The system issues red-light, vibration, and buzzer alerts, prompting quick withdrawal from high-heat zones. Data can be reviewed via mobile app or integrated with factory BIM systems.

Case Study 2: High-Temperature Leather Ironing

Risk Characteristics

The hot-pressing process uses high-temperature rollers to shape leather surfaces. Operators stay close to radiant heat sources while repetitively loading and unloading materials.

High-Risk Workers

Ironing machine operators, feeders, and loaders.

Heat Stress Triggers

• Standing posture near heat sources causes rapid temperature rise.
• Open factory layouts allow ambient temperature to rise uncontrollably.
• Workers may ignore signs like dizziness and fatigue due to task focus.

CMN Solution

CMN devices continue sampling every 15 seconds without interrupting workflow. Group-level alerts help supervisors arrange rotational cooling breaks or assign replacements based on exposure data.

Case Study 3: Enclosed Dyeing Rooms

Risk Characteristics

In closed dye rooms, ambient heat and chemical fumes combine to increase body heat and respiratory stress. The use of chemical-resistant clothing further reduces body heat dissipation.

High-Risk Workers

Dyeing operators, sprayers, pigment handlers.

Heat Stress Triggers

• Poor ventilation keeps thermal load trapped inside.
• Tight work schedules prevent rest and hydration.
• Thick uniforms restrict heat release.

CMN Solution

CMN wristbands are lightweight and do not interfere with hand or body motion. Recorded data creates individualized heat exposure curves, assisting managers with safe duty rotation and staff planning.

Advantages of CMN Wearable Devices in Leather Processing

• Customizable water-resistant and corrosion-proof materials for chemical environments.
• Triple alert system—light, buzzer, vibration—effective in noisy factories.
• Supports cloud-based reporting and mobile access for safety teams.
• Enables factory-wide deployment with remote supervision and individual tracking.

Conclusion and Recommendation

Leather processing facilities often concentrate multiple heat risks—long hours, chemical steam, and poor airflow. CMN wearables enable smart, predictive safety management by delivering early warnings and actionable insights. They help transform heat stress protection from passive observation to data-driven decision-making across tanning, dyeing, and pressing lines.
