High-Risk Groups and Scenarios

Different groups at flea markets face unique heat stress challenges:

• Vendors: Standing long hours at stalls under the sun with limited hydration opportunities.
• Security and cleaning staff: Walking across large markets in heat, wearing uniforms, and performing continuous labor.
• Visitors (especially elderly and children): Vulnerable populations exposed to crowding and poor ventilation in temporary tents.

Media reports from Asia, Europe, and the U.S. highlight incidents where market vendors and visitors collapsed from heat exhaustion, requiring medical response and causing disruptions.

Scenario Analysis: Four Critical Situations

a. Stall Setup and Preparation

Vendors and workers setting up booths in the morning sun perform heavy lifting without shade. Rapid body heat buildup makes this a high-risk period.

b. Peak-Hour Sales

Large crowds reduce airflow around stalls. Vendors wearing aprons or uniforms experience both radiant heat and cumulative fatigue, raising the chance of heat stroke.

c. Security Patrol and Cleaning

Support staff walk for hours across sun-exposed grounds. Wearing PPE or uniforms restricts heat dissipation, creating additional strain.

d. Dismantling and Closing

Late-night dismantling combines fatigue with residual ground heat. Workers loading heavy equipment often ignore early signs of heat stress.

Project-Level Impacts of Heat Stroke

Heat stroke at flea markets creates project-wide risks:

• Operational disruptions: Medical emergencies halt sales and reduce customer flow.
• Vendor losses: Affected stalls cannot complete sales, leading to financial setbacks.
• Visitor dissatisfaction: Negative experiences spread quickly via social media.
• Reputation risks: Market organizers face criticism and potential loss of future participation.

This is why Heat Stroke Prevention for Open-Air Flea Market is a management-level responsibility.

How CMN Devices Provide Solutions

CMN’s heat safety wearable device uses dual-sensor monitoring of skin and ambient temperatures. Sampling occurs every 15 seconds, and if anomalies repeat within 90 seconds, alarms are triggered via vibration, flashing red light, and sound. This ensures workers and vendors receive timely warnings.

The heat stress monitoring device integrates with apps and cloud platforms, giving organizers real-time oversight across vendors and staff. By deploying wearable heat safety PPE, flea markets can safeguard workers, reduce medical incidents, and maintain customer confidence.

Core Features and Customization Options

CMN devices provide tailored solutions for open-air markets:

• Dual-sensor detection with frequent sampling.
• Multi-signal alarms effective even in noisy market environments.
• OEM/ODM customization for design, materials, and features such as Bluetooth, NFC, or app integration.
• Cloud connectivity for market-wide safety monitoring.

These features give managers data-driven insights into worker safety and help ensure uninterrupted market operations.

Next Steps: Take Responsibility Now

Heat stroke prevention is not just an emergency response—it is a project-level responsibility for flea market organizers. By adopting CMN wearables, managers protect vendors and staff, safeguard customers, and strengthen the reputation of their markets.
