I practice safe handling with the handheld barcode scanners at the hardware store checkout.
-
Do not point the scanner at anything you do not intend to scan.
-
Keep your finger away from the trigger until you’re ready to scan.
-
Be aware of your surroundings including what is behind your target.
I would extend it to any gunlike, or vaguely gun shaped object, even those that cannot cause harm. Don’t become complacent with safety practices even when it doesn’t matter.




The sun is white, but the atmosphere reflects and scatters blue, allowing red and yellow to pass through. You see this effect in mornings and evenings when the sun’s light passes a much further distance in the atmosphere due to its low inclination. Your logic is sound, the clouds do appear orange at that time.
The only time you can safely look at the sun enough to determine its color normally is a sunset when it is tinted orange. I can see how he might have come to this conclusion but… wow…
