Aiming for a safe underground shopping mall-disaster prevention equipment in underground shopping malls

1. In the event of a fire

   The flowchart shown below is an easy-to-understand illustration of fire prevention measures and equipment. In the event of a fire, the detector is automatically activated, and at the same time, the sprinkler equipment is used to extinguish the water, while the smoke exhaust machine is activated. In addition, fire shutters (partly fire prevention shutters) are closed to minimize fires and prevent damage from increasing. We are working to improve and train facilities so that people in the underground shopping center can quickly move to safe places through emergency broadcasts and evacuation guidance.

2. In the event of a fire in kitchens, etc.

   Sensors are installed in the kitchen hood and at the connection between the hood and the duct, and when the inside of the hood reaches 180°C, fire prevention equipment (for fryers and ranges) works to prevent fire under the hood.
   At the same time, gas-linked shutoff valve works automatically to prevent secondary disaster from gas. In addition, a fire prevention dambar is installed at the connection of the duct main pipe, which operates at 180 ° C to prevent the spread of fire to the main pipe.

3. In the event of a gas leak

   In the unlikely event that a gas leak occurs, the gas leak detector installed at each store will be activated, an alarm will be issued, and at the same time, the disaster prevention center will be notified, and the security officer will immediately rush to the site for processing. In addition, if necessary, Osaka Gas and the Fire Department will be notified by telephone to ordinary customers via emergency broadcasts to evacuation guidance. Depending on the situation, the emergency shut-off valve is operated to stop gas supply in the underground shopping mall and ensure safety.

4. In the event of a power outage

   In the unlikely event of a power outage, emergency lights by the emergency battery automatically and instantly turn on (average floor illuminance of 10 looks), and the emergency private power generation equipment starts to start. Approximately 25 seconds later, the voltage is established, and after 10 seconds (about 35 seconds after the power outage), 1/4 of the illuminance (150 to 200 looks) is secured compared to normal conditions. In addition, this in-house power generation enables quick operation of disaster prevention equipment such as fire prevention shutters, fire pumps, smoke blowers and drainage pumps in the event of a fire.

5. In the event of a flood

   flood control is to prevent flooding by installing water stoppage plates in conjunction with sandbags to prevent flooding. In addition, we cooperate with connecting buildings that share entrances and exits in accordance with the flood control Activity Manual to prevent flooding. Our employees and self-defense flood control members regularly conduct flood control training before the rainy season to prepare for flood damage.

6. In the event of an earthquake

   It is said that "underground shopping centers are resistant to earthquakes." Even in the Great Hanshin-Awaji Earthquake, the underground shopping mall has become minor damage compared to other buildings.
   In the event of an earthquake, we will publicize the fact that the underground shopping mall is safer than above ground, and we will evacuate to the designated evacuation site by guiding security officers.
   In addition to conducting various trainings assuming an earthquake, we also conduct inspections of equipment and equipment affected by the earthquake as needed.
