Interesting your signature links to Wattsan a Chinese manufacturer of laser and CNC equipment with "An Lee" as a their CNC Specialist.

Yes, the signature link is to the manufacturer of the CNC machine on which I work. The signature was made for that if anyone is interested, I can give real advice on the machine as a user.  I am constantly improving my skills, so I read various articles, including the Wattsan site, and ask for advice on forums.

Definitely have a ventilation system setup.  Also only do veg tan leather.  Chrome tan emits a toxic gas when hit with laser.

Thank you very much for the advice.  There is ventilation + I close the lid of the machine when working, but if you work non-stop, of course, it doesn't help so much.

I cut chrome tan quite often you just need a good exhaust system and wipe down inside laser with light oil rag after cutting

Hmm... interesting! Okay, thanks, I'll look it up.

Your machine must not be good at all and people should avoid the company you work for that is  linked in your signature. Your post is a cut & paste from their website.

The majority of reputable, enclosed laser engravers will be rated as class 1 and considered safe under normal use with proper ventilation. 

Are you sure you have taken a close look at the machine. There is a cover and a hood. Then what is wrong with it. 
What I meant was, if you work without closing the lid, can the hood handle it, or do you have to close the lid? I haven't experimented, so I asked for an opinion.

Chrome tanned leather is actually perfectly safe to cut or engrave with a laser. That misinformation largely spread due to Glowforge's published list of dangerous and safe material. They simply didn't know for certain and so err'd on the side of caution. 

 

this video goes into great depth on the chemicals released and why it is safe: https://youtu.be/4_z2XHCtUtE

I use chrome tanned in my laser every day. :D

Oh cool! Thanks, I'll check it out!

If you go to his profile it gives Wattsan as his url, so presumably he's working for the company?

Um... unfortunately not. If I worked there, I'd have a lot of money, I'd be sitting in Bali right now, not replying to comments. 

I apologize for my English (it's not my first language). Maybe, that's why difficult to understand my message. I gave Wattsan(manufacturer's) as his url for other users, for information. Because in the future, I want to show my work on forum and maybe ask for advice. And, in order each time not to write manually brand machine I put it in the profile and the signature. if someone will be interested, perhaps...

The only reason you’re here is to peddle your laser machines. If you want to do it right, become an advertiser on this website.

I read in an article, Because smoke and bad smell are emitted during machining leather, it is necessary to use an exhaust system of the laser machine. When engraving and cutting of faux leather is performed, harmful for human's health stuff, hydrogen chloride, evolves. Inhaling of this gas can cause serious harm and even death.
 
I have a question, if the hood can not cope, you can use the lid of the machine (close during work).  For some reason, I thought all laser machines close just when working with harmful masters. or am I just lucky enough to have a cool CO2 laser machine? 

 

Yes, you are right! Most laser machines close during operation to protect the user from the harmful emissions. However, depending on the type of machine and its specifications, some machines may not have this feature. In that case, it is recommended to use a hood to ensure safety.
