Hello, everyone.
This is Enta.
On the way to the siteAre you reading the wind? lol
I bet you're like, "Huh?" lol
I’m guessing you use the highway when you go to job sites—do you ever notice that thing that’s always there?
That "thing" is a streamer!
By looking at this, I can get a general idea of what the wind will be like today.
It wouldn't hurt to know that guideline, would it?
It’s posted at the construction site office quite often, but nobody ever looks at it, lol.
It's the "High" setting on the fan.
During the summer, the temperature on site is quite pleasant.
Even at this level, it’s still pretty pleasant in the summer, but in the winter, it’s pure hell lol.
It's the kind of wind that makes you think, "Wow, this is pretty strong!"
At this point, the wind is blowing fairly strongly.
Crane operations will be prohibited.
Once the wind speed exceeds 10 meters per second, it’s a bit of a strong breeze—though it’s not something people can really tell.
"Moderately strong winds" is a term used in weather forecasts.
Strong winds are 15–20 meters per second.
The angle is so subtle that, to be honest, it's hard to tell, isn't it?
When you layer the streamers shown above, this is what it looks like.
I think the temperature you should keep in mind is around 70 degrees.
At this point, it’s a bit iffy whether we can use a crane.
This is a bit of a gray area that even the director might not remember, so let's be careful!
You can't underestimate the wind.
Especially when working on scaffolding, you’re bound to get blown around by the wind.
As the name “wind load” suggests, the load exerted by the wind is proportional to the size (surface area) of the object.
Just holding a scaffold board exposes you to a sudden, heavy wind load, which is why it’s extremely dangerous.
Working in extremely high winds is very dangerous, so I think it’s fine to prohibit work under those conditions.
This is especially true for us slope workers, since we work at high altitudes.
I recommend checking the wind conditions whenever you're out and about in the morning!
See you later.
*We will post the illustrator data for the streamers in the "Downloads" section of our website.
Feel free to take one if you need it.
