Heat-Related Illnesses as Serious Hazards: Ulsan City Completes Intensive Summer Inspections of Outdoor Worksites

Nine Sites Under City Jurisdiction... Strict Implementation of Five Basic Heatwave Prevention Guidelines
Strengthening On-Site Response Through Compliance with Work Standards and Measurement and Recording of Perceived Temperature

Ulsan City conducted inspections at nine outdoor work sites under its jurisdiction from July 21 to July 25, 2025, to prevent heat-related illnesses during the summer heatwave. The inspections confirmed that measures to protect workers' health were being actively implemented.

This inspection was carried out as a proactive measure to protect workers' health during heatwaves. It reflected the recently revised Occupational Safety and Health Act and Safety and Health Regulations, and aimed to strengthen the prevention of occupational diseases.

During this period, the city directly checked the actual working environment and monitored compliance with preventive guidelines, focusing on enhancing on-site response capabilities.

The main inspection items included: compliance with the five basic guidelines for heatwave preparedness (water, shade, rest, cooling equipment, emergency measures); measurement and recording of perceived temperature and application of rest standards; adherence to work time adjustment criteria; and education on heat-related illness prevention and emergency response.

On site, preventive measures such as providing cool water and saline glucose, and operating ice makers and cooling equipment were actively implemented to protect workers' health. In addition, perceived temperatures were measured twice daily, and when the temperature exceeded 33 degrees Celsius, workers were given at least 20 minutes of rest every two hours, in full compliance with legal standards.

Through pre-work safety meetings (TBM), workers were repeatedly educated on the symptoms of heatstroke and initial response methods, thereby further enhancing on-site response capabilities.

Previously, in June 2025, Ulsan City also conducted group education sessions on the prevention of heat-related illnesses for about 250 outdoor workers and supervisors, continuing its field-oriented preventive education efforts.

Going forward, the city will continue to provide health consultations and guidance on precautions for high-risk groups for heat-related illnesses, with occupational health physicians and health managers. It will also strengthen customized preventive measures that take into account both the working environment and individual health conditions.

An official from Ulsan City stated, "This inspection is not a one-time measure, but part of a practical response system that organically connects education, inspection, and follow-up management," and added, "As heatwaves become more frequent, we will continue to strengthen measures to protect workers' health."
