Hello, everyone.<\/p>\n

This is Enta.<\/p>\n

 <\/p>\n

Do you wear a helmet?<\/p>\n

Well, I guess I'm always using it, of course lol<\/p>\n

\"Safety<\/p>\n

Are you fastening your chin strap?<\/p>\n

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.<\/p>\n

People often hang their helmets on the brim of their hats during the summer to keep from getting sunburned.<\/p>\n

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

And that\u2019s especially true if the craftsman is in his or her 30s.<\/p>\n

Back when I was a supervisor, I used to think that if a craftsman couldn\u2019t even make a helmet properly, he shouldn\u2019t even bother coming to the job site.<\/p>\n

It gets annoying having to say this every single time, doesn't it? (But I'll say it anyway.)<\/p>\n

 <\/p>\n

Isn't that helmet a bit worn out?<\/p>\n

Isn't it a little yellowed?? lol<\/p>\n

Actually, it\u2019s kind of hard to swap them out when the stickers for each qualification are already on them.<\/p>\n

Sometimes those stickers serve as proof of certification. (Various certification stickers like the ones below)<\/p>\n

 <\/p>\n

\"Crane<\/p>\n

People who have a lot of stickers on their stuff are especially reluctant to change them\u2014it\u2019s like a badge of honor.<\/p>\n

\"Rank<\/p>\n

It\u2019s just like a rank insignia\u2014that\u2019s the image you get when you see it on a helmet, right?<\/p>\n

That's exactly why they're even more reluctant to replace their helmets.<\/p>\n

 <\/p>\n

However, helmets do have an expiration date.<\/p>\n

Five years at most<\/strong><\/span>That's it.<\/p>\n

Japan Helmet Manufacturers Association<\/a>
\n<\/span><\/span><\/strong><\/span>(It freaks me out that there's a club or association for just about everything lol)<\/p>\n

It's listed in the Q&A section here.<\/p>\n

 <\/p>\n

The Midori Safety website also includes the following information:<\/p>\n\n\n\n\n\n\n
Material<\/th>\nDisposal and Replacement Criteria<\/th>\n<\/tr>\n
Made of ABS, PC, and PE (thermoplastic resins)<\/td>\nWithin three years, even if no abnormalities are found<\/td>\n<\/tr>\n
Made of FRP (thermosetting resin)<\/td>\nWithin 5 years, even if no abnormalities are found<\/td>\n<\/tr>\n
Mounting Body<\/td>\nWithin one year, even if no abnormalities are found<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

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.<\/p>\n

\"Helmet
https:\/\/www.midori-helmet.jp\/dictionary\/6-2\/<\/figcaption><\/figure>\n

Please refer to items 2 through 4 in the table above.<\/p>\n

The expiration date for this part is one year, isn't it...<\/p>\n

Replace it at least once a year to protect your life<\/strong><\/span>It might be safer to do that, in many ways.<\/p>\n

That said, if you take good care of it, there won\u2019t be much wear and tear, so I think it\u2019ll last two years just fine.<\/p>\n

My helmet is already more than two years old.<\/p>\n

It's about time to replace it.<\/p>\n

There were also check items on the website.<\/p>\n

With so much free time on my hands, I started a blog. I\u2019ve been sharing my expertise on slope stabilization and answering all kinds of questions. As a result, I\u2019ve seen an increase in inquiries, questions, and orders from slope stabilization contractors, general contractors, and other major construction firms. My traffic on Ameblo grew to a reasonable level, so I decided to move on from Ameblo by acquiring my own domain in order to create a more user-friendly blog. I plan to continue sharing all my expertise openly and honestly here.
