Believe it or not, these two "simple" questions are very complex as there are literally endless factors to consider. Straight forwards to the two questions from akrapacs (yes I see they are from awhile ago).....
1.) Does anybody carry a laser with them as part of their everyday carry? = Yes, such as tour guides, docent, arborist, bosses at construction sites or open strip mining to point out to workers what to do.
2.) What type and power is safe to just have with me and use without requiring safety glasses for everybody nearby. = 5mW
Most of this falls under a "simple" 5mW laser pointer.
A stronger hand held laser will be used for greater distances or daylight situations but the user needs to be very careful as stated by other member above for issues such as the distance to the dot, reflections, type of surfaces the laser will be pointed at and so on and so on.
Not to start a flame war but compare it to a loaded .22 pistol. You, the user might be highly trained in the safe usage of the laser but what if you set it down for a moment or a friend asks to use it. Are they trained and know how to use it safely? Do they have safety goggles on?
A laser <5mW in most cases is okay for "everyday usage" as long as you don't do dumb things with it but a laser >5mW, not so much.
Hi LookinForLasers, welcome to the forum.
Most class IV lasers will not fit very well in your pocket unless it has a duty cycle because of the need for mass to dissipate heat.
It will be way to tempting to use the laser without safety goggles on if you do not have them present along with the laser.
