High-Risk Groups and Scenarios

Not every worker faces the same level of risk, but in battery manufacturing the following groups are highly vulnerable:

• Welding and packaging operators: Constant exposure to radiant heat during sealing and welding processes accelerates heat stress.
• Coating and calendering workers: They work in humid, hot environments that demand continuous physical exertion.
• Drying room operators: Tasks inside sealed or vacuum drying chambers provide little air circulation, making cooling nearly impossible.
• Maintenance crews: Wearing heavy PPE for chemical safety significantly reduces heat dissipation during long repairs.

Incidents in Asia and Europe have shown that battery plants are prone to worker exhaustion and heat-related hospitalizations, especially during peak summer production runs.

Scenario Analysis: Four Critical Situations

a. Welding and Sealing Workshops

These areas are hot due to radiant heat from sealing and laser welding equipment. Workers performing repetitive tasks near machinery often report dizziness and dehydration.

b. Coating and Calendering Sections

Machines used for electrode coating and rolling generate high humidity and heat. Workers face both environmental stress and physical workload, making them especially vulnerable.

c. Drying and Vacuum Chambers

Operators inside drying rooms deal with minimal airflow. Wearing protective suits intensifies heat load, and without monitoring, heat stroke becomes a severe risk.

d. Maintenance and Repairs

Technicians repairing machines or replacing furnace parts work under extreme heat conditions while wearing PPE, creating one of the most dangerous environments for heat stress.

Project-Level Impacts of Heat Stroke

Neglecting heat safety in battery factories brings project-level consequences:

• Production interruptions: Worker collapse near critical machinery may halt operations.
• Quality risks: Errors increase when fatigued workers operate precision machinery.
• Compliance risks: Regulators impose fines and audits after repeated incidents.
• Reputation loss: Customers may shift to suppliers with stronger safety practices.

This highlights why Heat Stroke Prevention for Battery Factory must be embedded into operational planning and management strategy.

How CMN Devices Provide Solutions

CMN’s heat safety wearable device applies dual-sensor monitoring of skin and ambient temperatures, calculating heat load with high precision. The system samples every 15 seconds, and repeated anomalies within 90 seconds trigger alarms via vibration, red light, and audible signals. Workers receive immediate warnings, and supervisors gain real-time safety oversight.

The heat stress monitoring device supports integration into plant dashboards and HSE/ESG reporting, enabling data-driven safety management. By adopting wearable heat safety PPE, battery factories protect workforce health, avoid downtime, and strengthen compliance with international safety standards.

Core Features and Customization Options

CMN devices are engineered for demanding industrial environments:

• Dual-sensor technology for accurate early warning.
• Every-15-second sampling with multi-signal alarms.
• OEM/ODM customization for materials, colors, and modules like Bluetooth and app connectivity.
• Cloud integration for real-time oversight of workforce safety.

These features are highly effective in battery plants, where heat, humidity, and PPE restrictions combine to make workers vulnerable to heat stress.

Next Steps: Take Responsibility Today

Heat stroke prevention is not a temporary solution—it is a project-level responsibility. By proactively adopting CMN wearables, battery factories safeguard workers, maintain production stability, and enhance customer trust.
