One year after the enforcement of the revised Industrial Safety and Health Act, NAC Co., Ltd. surveyed 500 labor managers at companies with on-site and manufacturing roles. The survey found that while approximately 90% were aware of the mandatory heatstroke prevention measures, about 20% were completely unaware of the penalties for non-compliance. A corporate dilemma was also highlighted: although providing water and beverages was the most desired future measure, the current implementation rate is only about 50%. Furthermore, about 30% of companies have not strengthened their measures since the revision. The law, which changed from a "best-effort" to a "legally binding obligation with penalties," applies to work environments with a WBGT of 28°C or higher or an air temperature of 31°C or higher.
