Confusing: Paint Mask Should Not Be Used With Paint?
Reader Mike is confused by this 3M Latex Paint and Odor Respirator with Valve. The front of the package lists "disposable aerosol spray paint cans" as something the mask "helps provide relief" from. However, the instructions seem to say that you shouldn't use it with paint spray. What should he do?
I was at my local hardware store to pick up some disposable, quick-use masks for spraying some nitrocellulose lacquer. I go to the right aisle and pick out a decently priced pair of 3M Latex Paint and Odor Respirator with Valve masks.
After going down the list of things this mask protected the user from, I quickly found "disposable aerosol spray paint cans" on the list and was satisfied. I bought the item and was about to use it, but had an inclination to read the instructions before going out to spray.
I read through the instructions and I was cautioned NOT to use this mask with "paint spray."
Should I use the masks or not?
Well, kudos on reading the instructions! The instructions are written in a confusing way, but we understand them to mean that you shouldn't use it with paint spray, "when particulate concentrations exceed 10 times the PEL/OEL, specific OSHA standards, or applicable government regulations, whichever is lower." If you're not sure that the substance you're spaying qualifies, you should check with an expert.
Do we have any experts in the comments?

At least according to OSHA, paint spray more refers to how it would be used in an industrial situation. Similar to say a paint booth used by an auto body shop. In these situations the paint is a finer spray, but also contains other aerosols and particulate that can be harmful.
For things like spray cans and even pressure paint sprayers, they don't add any chemicals and the particulate isn't small enough.
@heavylee-again: I think your's is the right one. Paint Spraying in abooth requires fresh air, and some people assume that the mask provide air, when they just filter it.
Paint Spray (for industrial applications) contains high volumes of xylene (same stuff in magic markers) and a full face with organic and particulate filter will work.
a particulate respirator (disposable paper kind N95 rated) will not protect from this.
for typical, run of the mill spray paint in a can you need to paint outside or in a well ventilated area (fans and open windows)as the airborne contaminates will make you a little light-headed.
if you must paint in an enclosed area with spray paint, you need either a SCBA or supplied air respirator. spraypaint contains a crapload of chemicals they use as a dispersion agent and as a drying agent. (propane, butane, xylene, blah, blah, blah)
the safest way to do it is out side in a dust free area.
@CarlR: Yup! "helps"
goes along with all those key phrases
"may"
"may aid in the prevention of.."
or "virtually" ect ect
@savvy999:
No. This mask is completely inappropriate for nitrocellulose lacquer. You can wear it and it will keep dust out, but for protection against the organic vapors in nitrocellulose lacquer, it is completely useless. You would do as well to wear a handkerchief over your face.
The package is confusing, but it has to be written that way to be within the regulations. I work with this all the time and you practically need a Masters in this subject to figure out exactly which mask you need.
This mask will provide relief for the uses it lists, but only for paint and odor (hence the name.) If you want protection from organic vapor fumes (and I can assure you that you do), you need to get a more appropriate respirator.
The previous guy got it in one.
Paint spray, which it is ok'd for is putting paint into a spraying machine that uses compressed air to spray the paint.
Cans of spray paint need something more beefy to be able to handle the propellants used.
You best bet would probably be to return it if it isn't opened and see if you can get a disposable respirator.
Having implemented OSHA programs from the ground up for 2 Navy aviation squadrons, I can tell you that if a mask is not fit-tested, it is not actually a "respirator". Disposible masks by definition cannot be fit tested, and consequently are really truly suitable--at least under the rules--as anything other than dust masks. Respirators used to block the breathing of fumes from volitile solvents must actually seal to the face and block the intake of any unfiltered air, which paper/fabric masks cannot do.











I would assume that "Paint spray" on the back means high-powered paint sprayers - and that disposable spray cans would be operating under a lower pressure that should be fine (i.e., less airborne dispersal)...
Of course, I'm not taking any blame for anything...
