maximum energy developed by most BB guns is 0.5 joules maximum - a
twentieth of the power from a funfair air gun. In normal use lightweight BB
pellets would certainly sting or bruise but not penetrate the skin. Safety
goggles prevent damage to eyes and safety clothing should also be worn. Have
commonsense and follow the Air Gun Code - see warranty & regulations
and Basic rules of use.
