When it comes to the use of disaster prevention supplies, people tend to focus on "natural disasters such as typhoons and earthquakes," but it is not limited to just that. Situations like power outages and water shortages can also occur due to damage or failure of infrastructure. This time, I will discuss the infrastructure that supports our lives and the risks associated with its aging. Infrastructure such as roads, bridges, water supply and sewage systems, and power grids deteriorates over time and requires proper maintenance. The useful life of infrastructure (the period it can be used) is influenced by many factors, including materials, design, construction methods, usage conditions, and environmental conditions. *For more details, you can view the related links.

In recent years, there have been many significant earthquakes, starting with the Noto Peninsula earthquake. Not only that, but there are also concerns about the occurrence of earthquakes such as the Tokyo metropolitan area earthquake and the Nankai Trough earthquake, and the probability of their occurrence is increasing day by day. As long as we live on the Japanese archipelago, earthquakes are an unavoidable disaster. What we can do is simply to "prepare." Earthquakes are phenomena caused by global-scale activities, and they possess a power that we, as living beings, cannot possibly contend with. Unfortunately, the saying "preparedness prevents worry" does not fully apply, but at the very least, there is a significant difference in survival probability between those who take disaster preparedness measures and those who do not. So, what should we prepare for? Humans are creatures with a highly developed brain, which comes at the cost of being very inefficient in terms of energy consumption, so when sleep and food are cut off, we become unable to function at an early stage. Additionally, we are vulnerable to infectious diseases and have low natural healing abilities, so we can become ill in unsanitary environments. *For more details on the column, please refer to the related links.

Japan is blessed with water resources, but it also has a humid and warm environment that is conducive to the growth of bacteria and fungi. However, compared to other countries, the hygiene environment and quality control are very well established, so food is generally safe. However, this safety assurance is only valid if the food has been stored properly. If a disaster causes a power outage, the food in the refrigerator can spoil quickly. Perishable foods are assigned a "consumption deadline," which indicates the safe period for consumption, while other foods have a "best before date," which guarantees a period with minimal flavor deterioration. Generally, items referred to as "emergency food" can be stored for long periods, as they have thoroughly removed moisture and oxygen, which cause spoilage, from the manufacturing stage, allowing for storage of about five years. *For more detailed information, please refer to the related links.

In times of disaster, not only emergency food but also long-term storage of drinking water is necessary. Naturally, river water cannot be consumed. While I don't think anyone would consider drinking from the Dotonbori River, even seemingly clean mountain streams contain many bacteria, including Campylobacter. River water contains not only bacteria but also many impurities, so while it can be made drinkable through filtration and boiling, unless you are someone who is seriously into camping, you probably wouldn't know the proper methods for heating or filtering. It is safer to avoid actions that could risk your health during a disaster. *For more details on the column, please refer to the related links.
