It won't slip anymore!
"A certain" expedition on a rainy day June 16 16:49
It's slippery.
It's raining.
This time when the road surface is often wet due to rain.
Do you ever slip your feet involuntarily?
In fact, the risk of slipping is highest on flat roads, not on slopes.
Our allies on a sunny day change suddenly on a rainy day.

A story that slipped on a rainy day
I'm Hitoshi Murahori, a reporter.
As an adult of Alafor, it is embarrassing to slip and fall, and there is a risk of injury, so I definitely want to avoid it.
However, on rainy days, there are more reports of "sliding" on Twitter.
"I fell flashy at the Braille block across the pedestrian crossing trying to get on the bus."
"I slipped on the manhole. I was almost run over by a car."
"On a rainy day pedestrian crossing The white line and the manhole cover are scary. "
There was also a post saying that he had a broken bone and witnessed being transported by ambulance.
The risk of slipping is a flat place
The Tokyo Metropolitan Government had previously summarized what kind of places are dangerous.
I thought it was a slope or stairs, but in fact, the one with the highest risk of slipping was the "sidewalk with no slope".
Don't be fooled by just falling.
9585 people die annually due to "falls, falls, and crashes."
(Reiwa 2nd year vital statistics)
2.6 times more than traffic accidents.
Looking at the breakdown,
▽ falls on the same plane due to slips, trips and staggers 7782 people
▽ falls from stairs and steps and falls on it 524 people
There is a higher risk of falling on a flat place.
I checked it so that it wouldn't slip
I just don't want to fall.
So I walked near my house and looked it up.
It's a steady survey of riding on everything on the sidewalk with the sneakers I wear all the time.
It was the gutter lid that felt the most slippery.
Just in case, I rubbed only one leg, but I even felt the danger of being taken away and falling.
It seems safer not to walk on the gutters on rainy days.
It was at the entrance and exit of the subway station that I felt the danger near the lid of the gutter.
Not only metal plates and tiles, but also stairs are slippery.
On the other hand, what was surprising was the white line on the pedestrian crossing.
The new white line that complements it has a good grip and I felt it was not slippery, but be careful of the old white line that has become tattered.
It was worn and slippery, and I was about to take my legs.
Then there is a metal lid such as a manhole.
When I tried all five types I found, including rectangular ones (NTT and fire hydrants) as well as round ones, the slipperiness was different depending on the one.
When I looked at the soles after the investigation, the grooves were worn out and almost flat.
This looks slippery.
I've been wearing it for a long time and I have to buy a new one.
There is a way to walk without slipping
Is there anything we can do to avoid slipping?
I asked these people.
"A certain expedition team A certain expedition
team" Kota Matsumoto and Akihiro Nishikawa of the comedy combination "Regular" who made a big break with this story.
Actually, the two are professionals in walking.
Two years ago, I got a qualification as a "health walking instructor" (certified by the Japan Walking Association) that teaches how to walk properly for health.
It is said that he felt the importance of walking while visiting nursing care facilities nationwide and showing off stories.
Regular Kota Matsumoto
"When I heard the story of the resident of the facility, I heard that I should have been exercising more. It would be a good exercise to walk. Then, if you study, you shouldn't. "
A non-slip point on a rainy day.
First of all, it is called shoes.
For example, leather shoes.
Leather soles are said to be slippery and slippery.
Heels with a small landing area are also slippery, so be careful.
Anti-slip rain shoes and sneakers are recommended.
Furthermore, it is said that there is a point in how to walk.
It is usually said that landing from the heel is the correct way to walk, but there is a risk of falling on a rainy day.
For this reason, on rainy days, if you lean forward and step on the ground with the entire sole of your foot, it will be difficult to slip.
Also, on rainy days, mud and water splashes are a concern, but it seems that you can prevent it by putting your feet straight in the direction of travel so that you do not get into the inner thighs or outer thighs.
Regular Akihiro Nishikawa
"I think I'm doing it naturally so that I don't get into a big stride when it's raining, but it's harder to slip if I do it in an easy-to-understand manner."
Sliding standard BPN
Actually, there was a standard to measure slipperiness.
The smaller the slip resistance value (BPN), the easier it is to slip, and conversely, the larger the number, the harder it is to slip.
The Nippon Road Association recommends that BPN40 or higher is a safety standard for asphalt and wet roads.
This is one standard, and many of the things on the sidewalk such as white lines and manholes are maintained with reference to BPN40 or higher.
However, this standard is only in the maintenance stage.
In the subsequent periodic inspections, the slip resistance value was not measured, and it was said that repairs would not be performed because it was slippery.
In fact, there are many places where the surface is worn and slippery due to the passage of people and bicycles.
Secret plan to prevent slipping
However, measures have begun to make the roads less slippery.
For example, the white line on the road.
In order to make it less slippery, it is said that "aggregate" such as gravel and sand and glass beads that also play the role of reflective material are kneaded.
Also a manhole.
The managers of water services, sewerage, electricity, gas, etc. are different.
The Tokyo Metropolitan Waterworks Bureau stipulates that patterns and letters should be grooved so that the surface may be uneven, and the width and depth of the grooves are also specified.
If the citizens point out that the sewerage department in Yokohama City is slippery, it seems that they are responding by changing the lid to a lid with a finer surface unevenness and a shape that is less slippery, or by applying an anti-slip agent. ..
Some anti-slip agents use pine rosin and glass beads.
The Braille block has its own standards set by the Tokyo Metropolitan Government, and emphasizes slip resistance rather than BPN'50 or higher and the Japan Road Association standard 40.
The slipperiness varies depending on the material used.
Many of the platforms at stations are made of concrete, which is said to be difficult to slip.
Some manufacturers dedicate vinyl chloride products to indoors because they are slippery outdoors.
Development of synthetic resin with a rough surface to prevent slipping is also in progress.
"Avoid Braille blocks"
On the other hand, there are also such voices from visually impaired people.
Mr. Shoichi Kudo, Japan Association of Visually Impaired People
"It may be an obstacle for healthy people, but people with visual impairments such as blind people have no choice but to walk along something when walking alone, and Braille blocks. Please be aware that you cannot go straight without it. It is designed to stand out in yellow so that even people with low vision can see it, so recognize that people who can see can be obstacles and avoid it. I hope you can pass it. "
While healthy people sometimes complain that they have slipped or stumbled on Braille blocks, there are few such voices from visually impaired people.
Mr. Shoichi Kudo, Japan Association of Visually Impaired People
"I would like you to prevent it from slipping more. Maybe it's because I'm walking with caution that it's slippery. "
Regular non-slip story
Finally, I heard the two regular "non-slip stories".
Regular Kota Matsumoto
"When I showed off the story at a nursing facility, I heard that everyone at the facility was a big fan of us, but the two of us said," A certain expedition team A certain expedition team Hi! Hi! Hi, Hi "Hi!", And the grandpa and grandma who were watching it said "Hi?" After a while. "
Regular Akihiro Nishikawa
"I don't know. No, I'm already laughing and licking the wounds."
"Well, in my case, I have a gag that faints. Even if I fail. last…"
"Guu ~"
It's not smooth.
