Regulation
Preventing Heat Hazards in High-Temperature Outdoor Work Is Now a Legal Duty for Employers
Under Article 324-6 of the Occupational Safety and Health Facilities Rules (Taiwan), employers whose workers perform outdoor work must take the necessary hazard prevention measures according to weather conditions to guard against heat illness caused by high temperatures. Failure to comply is punishable under the Occupational Safety and Health Act by a fine of NT$30,000 to NT$300,000.
The Occupational Safety and Health Administration (OSHA), Ministry of Labor has also issued the Heat Hazard Prevention Guidelines for High-Temperature Operations (3rd edition, amended June 20, 2025), which classify heat hazard risk into Levels 1 to 4. When the risk reaches Level 4, shading and cooling equipment must be installed, and shaded rest areas and sufficient drinking water must be provided.
The Ten Hazard Prevention Measures Required of Employers Under Article 324-6
To adjust working hours and increase patrol frequency at the right time, you first need real-time, accurate heat hazard data from the work site. The Heat Safety Guardian enables managers to take appropriate protective measures promptly, based on actual on-site measurements.
Product Overview
See On-Site Heat Risk Clearly, Protect Frontline Workers
Integrated AIoT monitoring makes hard-to-detect heat hazard risks visible in real time.
Real-Time Environmental Monitoring
Simultaneously measures air temperature, humidity, black globe temperature, wind speed, and wind direction, and displays the WBGT heat stress index in real time.
Eliminate Traditional Blind Spots
Overcomes the limitations of time-consuming manual recording that cannot raise timely warnings, providing continuous, around-the-clock visibility into on-site environmental changes.
Automated Response
When readings reach the alert threshold, the system immediately activates on-site alarms and remote notifications, helping managers respond in time.

Alert Mechanism
Three-Layer Synchronized Alerts
When monitored readings reach your custom alert thresholds, the system simultaneously activates on-site warnings, remote notifications, and cloud logging.
On Site: Real-Time Audible-Visual Alarm
A high-decibel, high-brightness audible-visual alarm is triggered immediately on site, alerting workers to heat hazard risk.
Mobile: LINE Push Notifications
The system simultaneously sends alerts to managers via LINE push notifications, making it easy to monitor site conditions remotely.
System: Cloud Data and Event Logging
Environmental data and event records from before and after each alert are retained automatically for later review, tracking, and auditing.

Specifications
Sensing Parameters and Specifications
| Monitored Parameter | Measurement Range and Accuracy | Notes and Technical Features |
|---|---|---|
| Air temperature | -30 ~ 80°C, ±0.5°C | High-sensitivity digital sensing with fast response and low error |
| Humidity | 0 ~ 95% RH, ±5% | Anti-condensation design for stable operation in high-humidity environments |
| Black globe temperature | -40 ~ 100°C, ±0.2°C | Accurately measures environmental radiant heat (including direct sunlight and radiant heat from hot machinery) |
| Wind speed | 0 ~ 70 m/s (±3%) | Assesses microclimate heat dissipation and can assist facility ventilation control |
| Wind direction | 0 ~ 360° (±3°) | |
| WBGT heat stress index | Calculated from air temperature, humidity, and black globe temperature | The system computes WBGT in real time and proactively issues alerts when readings become abnormal, supporting effective heat hazard management |
