The recommendations are that IPA should not be closer than 50cm to any electronics, to have a ventilated area and the most obvious to use protective gloves. If you are going to use a fan in order to remove the fumes from your room, the fan needs to be approved for flammable vapours.
I try to open the box for a few seconds and hold my breath. The other thing is sometimes spilt resin will get on my fingers and I apply a small bit of the IPA to a paper towel to wipe it off my hands. Anyone know if its particularly dangerous to get this stuff on the hands?
Uncured resin is not good for you. Some people will get irritations and even allergies. You should always use protective gloves. And remember that uncured resin will penetrate the gloves after a while so change gloves regularly.
I don’t get headaches, though I do get a bit of a tight throat. Guess everyone is different in reaction. I will start wearing a mask anyway. Sure breathing this stuff doesn’t do any good in the long run.
I am not a doctor and I have no idea about IPA but I do not think is good to breath it on a regular basis (just common sense). Never seen breathing IPA as a recommended healthy habit
I always wear gloves and a half face mask while manipulating resin, IPA and prints.
Yeah I always wear gloves now. I either try to hold my breath or wear a full (breaking bad style) mask. I heard solvent fumes can over time rot cartilage in your nose so definitely not good to breath in.
I am a design engineer and new to the forum. I am trying decide between a Form2 or a MakerGear M2 with some sort of enclosure. I am curious as to the safety of the resin and post-processing fumes. My office is in the basement of our house. There are only four small slider windows and none of them are in the office. One is in the mechanical room where the utility sink is however. Is anyone, in addition to the starter of the thread, have this sort of situation?
Just keep the container closed when you can, the only time you need to open the IPA is to clean off a print for a short amount of time, and that’s not going to cause any problems. Just avoid having your face near the container when it’s open. As for resin, same thing just avoid keeping containers open when you don’t need to.
I forget to use gloves because I was too excited with my print. I have small wounds on my hand because I used too much soap over time on my hands. When I tried to put print inside IPA 99% i felt burning on wounds. Imedietely I went and wash my hands, is it too bad?
For taking care of any air concerns there are two approaches, one as venting the air to an outside vent using an explosion proof blower and a fume hood.
If using this method its extremely important that the blower is rated for handling potentially flammable fumes and that all safety guidelines are followed when installing and the system is used.
If your designated cleaning area is setup well it really doesn’t take much to control and remove fumes.
There are also some small stand alone carbon based air filtration units that are rated for handling flammable fumes but I personally haven’t tried this method yet.
IPA isn’t terrible by itself, it is used to sterilize wounds, the main thing is it’s not good to breathe and it can dry out your skin. Resin is not good to get in a wound so it wouldn’t be great to get IPA that has dissolved resin on your hands if you have wounds.
Straight from the doctors on the internet “Isopropyl alcohol slows these functions and may shut them down altogether. … Inhaling large amounts of isopropyl alcohol can cause nausea, vomiting, irritation of the nose and mucous membranes, throat irritations, and even difficulty with breathing as coughing can occur making it difficult for you to catch your breath.”
