Glazing in a wall enclosing a bathtub or shower is generally required to be safety glazing when the bottom edge of the glazing is less than what height above the standing or walking surface?

Glazing at tubs and showers whose bottom edge is less than 60 inches above the standing surface is a hazardous location requiring safety glazing due to slip-and-fall impact risk. 48 inches is lower than the trigger, and 72 and 80 inches are higher than the 60-inch threshold.
