With the frequent occurrence of extreme high-temperature weather around the world, the construction industry is undergoing a digital transformation in safety production management. Recently, a WBGT (Wet Bulb Black Globe Temperature) monitoring system capable of real-time monitoring of the comprehensive heat stress index has been put into use in several key construction projects, building a scientific safety line against heatstroke for outdoor construction workers.
Smart Construction Site: From “Experience-based Judgment” to “Data-driven”
At the construction site of a certain super high-rise building project, the newly installed WBGT monitor is continuously collecting environmental parameters such as temperature, humidity, radiant heat and wind speed. Engineer Wang, the project safety director, introduced: “Traditional high-temperature warnings only rely on temperature data, while the WBGT index comprehensively considers four environmental factors and can more accurately reflect the actual heat load of the human body.” ”
The system updates the hazard level in real time through the on-site LED display screen and sets up response measures for different areas: when the WBGT index reaches 28℃, the fog cannon cooling equipment is automatically activated. When the temperature exceeds 30℃, adjust the period of high-intensity work and distribute heatstroke prevention drinks containing electrolytes to the workers. When the temperature reaches above 32℃, immediately stop open-air operations and transfer the workers to a cool rest area.
Regional application: Protection strategies tailored to local conditions
In the construction projects of cross-sea Bridges in coastal areas, the WBGT monitoring system has demonstrated special value. Due to the special environment of high humidity and strong radiation by the seaside, the actual heat stress risk monitored by this system is often 2 to 3 grades higher than the weather forecast. After analyzing the data, the project department found that even with a temperature of only 33℃, the WBGT index could still reach a dangerous level when combined with high humidity. Based on this, they re-established a more targeted shift system.
Remarkable achievements: Dual improvements in safety and efficiency
Statistics from a certain construction group show that since the full implementation of the WBGT monitoring system, the incidence of heat-related diseases at each project site has decreased by 75% year-on-year, and the delay in construction period caused by high temperatures has decreased by 42%. What is more worthy of attention is that the workers said, “The work arrangements during the high-temperature period are now more scientific and reasonable, and they feel more at ease when working.”
Industry response: Standards and training are advanced simultaneously
At present, WBGT monitoring has been incorporated into the recommended standards for safety production at construction sites in many places around the world. Many large construction enterprises not only have fixed and portable WBGT monitoring devices, but also have carried out specialized heat stress protection training, teaching workers to identify the signs of heatstroke and master preventive measures.
Future Outlook: Intelligent and Interconnected security management
Industry experts point out that the next-generation WBGT monitoring system is deeply integrating with wearable devices and artificial intelligence forecasting models. In the future, not only will more accurate early warnings be achievable, but also personalized heatstroke protection plans can be provided based on each worker’s physical condition and work intensity.
With the increasing emphasis on the protection of workers’ rights and interests in the construction industry, the popularization of WBGT monitoring technology indicates that construction safety management is moving towards a more refined and scientific direction. This seemingly simple technological revolution is providing a solid “protective umbrella” for countless construction workers in the scorching summer.
