I posted this in your same question thread in the boro room.
You will need eye protection, extinguisher, and a ventilation system, preferably one that is a lot more than just an open door and fan.
I also wear a respirator, Bear in mind that you should always feel the same way you leave a torching session as the way you went into it except for maybe being tired.
No dizzyness, shortness of breath, headaches, neck aches, chest aches, eye strain, burning arm or face skin from ambient heat etc. If you set your workbench up right, with the right equipment for you and build a proper exhaust system you will feel fine after torching.
And safety first. ALWAYS...
Exit door safety, extinguisher easy to reach, and maybe some aloe plants for any burns.
Be safe, have fun.
You may not like it but it's the truth!
