Walking through the mist is considered a secondary exposure.
Depending on the amount you walk through effects can be anywhere from sneezing/runny nose/coughing a bit to possible decapacitation.... but for that to happen, you ... well.... screwed up?
Fox Labs comes in foam, straight stream and cone (fog).
For personal use, I chose the straight stream since it would be less likely to cause a secondary exposure, even if used indoors.
This stuff sprays out about 15+ feet. The downside to the stream is that the "victim" doesn't get much into his lungs.
The cone works great in ideal conditions (which Mr. Murphy makes sure never happens) since that gets in the eyes AND lungs. You take a deep breath of this stuff and you do NOT want to breathe anymore! (I had to be reminded, as did several other police officers who took the instructor's course)
Foam is good if you're only going to use it indoors. There's virtually no chance of a secondary exposure but there's virtually no chance it'll get into their lungs either. There's been some reports of people scraping off the foam and tossing it back at the good guy, but I don't personally know of any cases.
Bottom line is if you carry it, carry a straight stream. If you use it, try and keep the wind at your back if possible but if you have doubts, spray them and move out of the way of the fog.
Actually, you should move in an "L" shaped manner after spraying someone since if they're planning on going after you, they'll go to the last place that they saw you.... but they'll be blind.
Wondering how long I can keep up this serious stuff,
I remain,
