I think that the wooden jungle gym fire of Jingu Gaien Fire could be prevented. The way

Although it is an article that surrendered a little while ago, the blog that I described has disappeared, so I will upload it again with almost the same contents.

It seems to have been described on November 7, 2016.

Jingu Gaien Wooden Jungle Gym Fire Protection Method

As the title suggests, I think that the wooden jungle gym fire at Jingu Gaien could be prevented. It was a very painful fire.
I don’t think this should be repeated in the future.

It doesn’t burn just by painting

I’m afraid later, like Janken, but I think it would have been better if I made the wood flame-retardant. Soufa, our flame retardant, is effective in making wood (cellulosic material) flame retardant.
It can be made flame-retardant just by spraying or painting, so it can be made flame-retardant even with a wooden jungle gym at Jingu Gaien.
In some reports, it is said that the sawdust was ignited by the heat of the light bulb, but even sawdust can be given a performance that does not spread by blowing soufa.

You can easily do it just by spraying. The video below is a video of spraying soufa on a tissue.

And the image that ignited the tissue is below. It does not spread and becomes charcoal.

Burning comparison of treated and untreated tissue. On the left is the processed tissue. I ignite at the same time and compare the burning speed. The same can be done with sawdust and wood.

The main raw material of soufa is boric acid. Boric acid is a highly safe substance that has little effect on the human body. However, it is known that it gives very high flame retardancy to cellulose such as wood and sawdust, and is partly distributed as a noncombustible liquid used for noncombustible wood.

By applying soufa, an oxygen barrier film is formed when heat is applied, and the surface is carbonized to prevent further combustion.

This is a photograph of the test piece, but the surface foams like this when ignited.
This film blocks oxygen and does not burn anymore.

This can give similar performance if it is a substance mainly composed of cellulose such as paper and sawdust.
If you spray soufa on the wooden jungle gym fire at Jingu Gaien this time, I think that it did not spread so rapidly.
I am sorry for the later criticism article, but I felt like that.

The story changes, but in Tokyo the concept of a non-combustible special zone has been launched since the Governor Ishihara era. However, this is based on the principle of “reduce the wooden structure and replace it with concrete” and “reduce the wooden structure and widen the road to prevent the spread of fire,” and there is no mention of measures for existing wooden dense areas. Hmm.
At the moment, people living in those areas seem to have no choice but to rebuild or move. However, it is a fact that there are many elderly people in those areas, and their motivation for rebuilding is low, and there are also cost issues.
I think it is necessary to pay more attention to flame retardant and flameproofing of existing houses.

Every year in the winter, there will be reports of arson from shrines and temples every year.
Old buildings are said to be easy to ignite because the wood is dry. It will also be important in the future to implement flameproofing and flame-retardant construction on these buildings.

Awareness regarding flame protection in existing buildings seems generally low. There is seismic protection before flame protection, and costs lie before earthquake resistance.

Through the spread of soufa, we would like to reduce the number of people affected by fire as much as possible.
From such a thought, we provided flameproof spray soufa free of charge to the affected area of ​​Kumamoto earthquake.

It is a record of activities when our officers entered the Kumamoto stricken area.

I am glad if you can use it for fire prevention in the affected area in winter.

The title and the story are diverted, but in the event of an earthquake disaster, many people will not be fired.
The image of the tsunami caused by the Great East Japan Earthquake was so strong that it was difficult to imagine the relationship between the earthquake and the fire. However, the damage was widened by the fire in the Great Hanshin Earthquake.

soufa originally specialized in flame retarding wood.
In addition to our company, there are several companies in Japan that study the flame retardancy of wood. Wood can be said to be inseparable from Japanese architecture, and it is a material that must be faced.
Also, don’t forget that there are already many wooden buildings in Japan.
The flame retardancy of existing buildings is almost untouched.
The fires of Shinjuku Golden Gai and Pontocho in Kyoto are also new to memory. Tree dense areas are still all over the country, and wooden buildings are still left in landscape conservation areas.

It is easy to just criticize Jingu Fire this time, but what kind of measures are needed to avoid repeating it? Also, what can be realistically executed at cost? Isn’t it time to think about that?

We advocate using soufa to “take time to escape”.

Since Japan is said to be a great earthquake country, much cost and research is being done on earthquake resistance. However, even in Japan, where there are many wooden houses, research on the incombustibility of timber is still in the middle of the road, and honestly there is not much budget.
I think this criticism will bring much criticism to the wooden construction of the new National Stadium.
However, there are already countless wooden buildings in Japan. Many of the historical temples and shrines throughout Japan are wooden. You can’t look away from it.

Also, there seems to be a lot of criticism about art in this fire. In fact, more and more colleges and artists are receiving orders for soufa recently.
It seems that artists who are doing creative activities are also considering flame retardancy.

Certainly, if a wooden jungle gym was made of non-combustible wood, such an accident might not have occurred. (Sawdust burns …)
However, it is also true that it is not actually a cost feeling that students can purchase.

I think that it is required to take fire prevention measures simply and cheaply.
