The Flashbang is designed to let the blast and light out of the container and not to generate any shrapnels.
The grenade produce a 1 million candela light flash and a blast of 170 to 180 decibels. They affect your body suddenly, but do not leave any damages of lasting character. The flash light makes the eye to loose forcus for about 5 to 10 seconds and the blast affects the semicircular canals of the ear, making it hard to maintain balance.
The Flashbang we used contained ammonium (perchlorate(?)) and magnesium which can cause burns to exposed surfaces of the skin (in some cases).
I cannot think of any penetration damages by the Flashbang, though it might be possible in case of manufacturing failure.
