What Is the Service Life of Construction Site Helmets? An Explanation of When to Replace Them and Disposal Standards

Hello, everyone.

This is Enta.

先日から、なぜかクレーンの免許を取りに来ています。

Crane Operator License (5 metric tons or more)

5t以上の移動式クレーンです。

なぜかって。。。来年からうちの社員にも取ってきてもらうので、先に私がw

別に5t以上のラフタークレーンを買うとかそんな気はサラサラありません。

ただ、5t以上吊れるって思うとだとなんだかカッコいいじゃないですか!!?


But that's beside the point.

Do you wear a helmet?

まぁ当然に使用していると思います。

Safety First

Are you fastening your chin strap?

If you don't fasten the chin strap, the helmet could come off in the event of a fall, and then it would all be for nothing.

People often hang their helmets on the brim of their hats during the summer to keep from getting sunburned.

This is just ridiculous. To be honest, as a director, I don't even want to talk to someone at that level.

And that’s especially true if the craftsman is in his or her 30s.

昔は監督の立場で、ヘルメットもまともに出来なければ現場に来なければ良いのにって思っていました。

It gets annoying having to say this every single time, doesn't it? (But I'll say it anyway.)

 

Isn't that helmet a bit worn out?

Isn't it a little yellowed?? lol

Actually, it’s kind of hard to swap them out when the stickers for each qualification are already on them.

Sometimes those stickers serve as proof of certification. (Various certification stickers like the ones below)

 

Crane Sticker

People who have a lot of stickers on their stuff are especially reluctant to change them—it’s like a badge of honor.

Rank Insignia

It’s just like a rank insignia—that’s the image you get when you see it on a helmet, right?

That's exactly why they're even more reluctant to replace their helmets.

 

However, helmets do have an expiration date.

Five years at mostThat's it.

Japan Helmet Manufacturers Association
(It freaks me out that there's a club or association for just about everything lol)

It's listed in the Q&A section here.

 

The Midori Safety website also includes the following information:

Material Disposal and Replacement Criteria
Made of ABS, PC, and PE (thermoplastic resins) Within three years, even if no abnormalities are found
Made of FRP (thermosetting resin) Within 5 years, even if no abnormalities are found
Mounting Body Within one year, even if no abnormalities are found

According to the table above, the helmet itself lasts 3 to 5 years, but since the headband lasts only 1 year, it needs to be replaced after 1 year.

Please refer to items 2 through 4 in the table above.

The expiration date for this part is one year, isn't it...

 

Replace it at least once a year to protect your lifeIt might be safer to do that, in many ways.

And, actually, there are plenty of medal stickers for sale online.

グーグル検索で「ヘルメット 資格シール」で検索してみて下さい。

沢山ありますよ。
