Minimizing Environmental Damage in Case of Accident or Disaster

Daikin has systems in place that allow it to minimize environmental damage if there should be an accident or calamity at Daikin production sites around the world. Our Disaster Prevention Manual details how to deal with emergencies like chemical and oil leaks, spills, and earthquakes. The manual is the basis for regular emergency drills.

Training held at each plant (fiscal 2021)

  Main training
Sakai Plant Emergency training with added features based on consideration for prevention of COVID-19 in evacuation and roll calls in preparation for earthquakes is held four times a year at Rinkai Factory, and twice a year at Kanaoka Factory
Water quality emergency training is conducted at Kanaoka Factory and Rinkai Factory to prevent outflow of oil leaks while disinfection of emergency supplies with alcohol is performed based on consideration for infection prevention
Shiga Plant Emergency materials storage check patrol and water quality accident and emergency training, practical training on recovery methods for oil leaks and leakage prevention measures (conducted once in total)
Yodogawa Plant Training on evacuation activity that avoids the 3 C's in place of the three cancelled training sessions due to the COVID-19 pandemic, fundamental action training for new employees, chemical accident response training, and parts training for oil spill and leak prevention measures
Kashima Plant Evacuation training was held based on the scenario of plant accident and tsunami caused by an earthquake, while disaster prevention training was held two times based on the scenario of a fire occuring as a secondary disaster
Practical training on oil recovery and sandbag installation

Monitoring Environmental Standards

Strict Management at Manufacturing Bases Exceeds Legal Requirements

Daikin controls air and water pollution using voluntary standards that are stricter than national environmental standards and local government by-laws. We regularly measure our various environmental impacts and work to either prevent or decrease them.

Monitored environmental data for Daikin Industries, Ltd.'s four manufacturing bases is on the Daikin website.

Measures for Soil and Groundwater Pollution

Dealing with Soil Pollution at the Yodogawa Plant

At the Yodogawa Plant, it was discovered that the site's groundwater contained concentrations of chloroethylene that exceeded environmental standards. This was reported to the Osaka Prefectural authorities, and we continued to pump up groundwater to prevent pollution from spreading beyond the boundaries of the site.

Groundwater Cleanup Continues at the Kashima Plant

In 2000, the concentration of organic chlorine-based compounds in groundwater at the Kashima Plant was found to exceed environmental standards. We continued groundwater cleanup, and confirmed that pollution concentration in the groundwater was reduced to below the standards through measurements in fiscal 2020. We have continued our cleanup efforts and conducted measurements in fiscal 2021.

Storage and Treatment of PCBs

Implementing Strict Management and Disposal of Equipment Containing PCBs

Daikin abides by national laws in properly managing equipment containing PCBs (polychlorinated biphenyls). We have been disposing of waste with high PCB concentrations based on PCB disposal plans of the Japan Environmental Storage & Safety Corporation (JESCO), and we were one of the first companies to register with JESCO. Waste with low PCB concentrations is being disposed of based on a Daikin disposal plan.
