Our hospital has been appointed as the core site among the local disaster base hospitals in the north-eastern ward of Tokyo. Our hospital moved from the risk 5 area regarding the earthquake to the risk 2 area in January 2022. However, regarding the inundation danger area caused by the Arakawa flooding, we practice various preparation measures in a new hospital to play a role as the core facilities. We established four elevators (EV) of the earthquake-resistant performance S14 class. Regarding flood measures, we surrounded a hospital ridge with a waterproofing retaining wall of 2.4 m and laid earth up to 2.0 m off the ground and prevented the inundation. We placed the important section above the second floor. The ambulances reach the second-floor deck on a slope. EV is situated on the second floor or above and can drive continuously even if flooded in the EV pit. As a conveyance method when the neighborhood was surrounded with water, it comprised an amphibious vehicle. We developed and deployed the NBC (nuclear, biological, and chemical) ambulance which mobile operations and emergency procedures to be performed in the car. We carry out the natural disaster and CBRNE (chemical, biological, radiological, nuclear, and explosive) training of the hospital once a year.
