Another issue" in times of disaster: odor problems in evacuation centers

Evacuation centers are set up after every disaster, such as earthquakes and floods. These shelters, where people who have lost their homes temporarily live, must be a space that provides security and safety. However, the environment of such shelters is also faced with the issue of "odor," which is difficult to see on the surface.
When people gather together to eat, sleep, defecate, and conduct other daily activities in a confined space, they inevitably produce a variety of odors. The mixture of a wide variety of odors, such as sweat, body odor, toilet odors, leftover food scents, and moldy odors caused by humidity, accumulates daily stress on the people in shelters.
An unpleasant odor in the air is more than just an inconvenience. Odors can cause people to lose their appetite, have trouble sleeping, and feel uncomfortable around other people. For people under extreme stress in the aftermath of a disaster, air quality is an important factor that has a significant psychological impact.


Complex mixture of bad smells

The odors generated in shelters are not due to a single substance, but are a complex mixture of various components. For example, gaseous substances such as ammonia, hydrogen sulfide, and methyl mercaptan, as well as mold and bacterial metabolites, are in the air.
Moreover, they intensify over time and tend to linger in a person's nose. General measures such as deodorant sprays and air fresheners are not a fundamental solution. Simply "masking" the smell by adding fragrance can even increase discomfort.
In order to accurately remove such "invisible sources of stress," scientifically supported deodorization technology is required, not merely a temporary fix.



Changing the Air with the Power of Science--Protect Arts Technology

In response to these challenges, Protect Arts has developed proprietary deodorizing technologies with the mission of "reducing stress from the air. The company's products employ a system in which the main components of bad odors are captured by a filter and then decomposed and removed through catalytic and oxidative reactions.
The key point is the approach of "chemically cutting off the source of the odor. In particular, a multi-layered reactive filter with a high decomposition performance for volatile components such as ammonia and hydrogen sulfide is used, making it possible to deal with complex odors.


Eliminating odors is a good way to take care of your mind.

During a disaster, people who spend time in evacuation centers are faced with a great deal of anxiety and loss. Among them, unpleasant odors in the space can unintentionally increase stress and deepen psychological damage.
Especially in shelters where there is little privacy, problems can occur, such as strained relationships due to odors or the inability to provide necessary care because of one's own smell.
Odors are invisible, but they certainly affect people's behavior and emotions. And removing it means more than simply "cleaning" the air. Reducing odors creates a sense of security, brings us a little closer to others, and improves the quality of our sleep. It is a small but significant component of shelter life.


Deodorization is a new form of disaster prevention

Until now, disaster preparedness has focused on food, water, and bedding. However, "air quality" should also be considered as an important part of future disaster preparedness.
With such "future disaster prevention" in mind, ProtectArts is focusing on the development of devices that reduce stress caused by odors. Deodorization equipment may still be a new concept, but the comfort and psychological security it provides will be increasingly sought after in the future.
Air is shared by everyone there. That is why creating a space where everyone can breathe deeply and safely is extremely important in disaster care.



Finally, the power of "smell awareness

Facing the smells in shelters head-on is also about protecting "humanity". Comfort and dignity should be preserved, no matter how harsh the conditions.
Stress caused by odors is difficult to put into words and difficult to complain about. However, being prepared to deal with it ahead of time can help protect the vulnerable in a disaster.
The efforts of ProtectArts are responding to the invisible presence of "air" with the power of science and presenting a new option to support people's mental health. The day may come in the not-too-distant future when "odor-free space" will become the standard in future evacuation centers.
