At what height is glazing in walls of a shower or bathtub considered a hazardous location?

1. 48 inches

2. 60 inches

3. 66 inches

4. 72 inches

The correct answer is: 60 inches

Glazing in walls of a shower or bathtub area is considered a hazardous location when it is installed at a height of 60 inches or less above the standing surface. The reason for this designation relates to the potential for impact by individuals who are using the shower or bathtub, especially when the space is wet and slippery. Glazing refers to the use of glass in buildings, and when located in areas where there is a risk of a person falling against it, it must meet specific safety standards. At this height, there is an increased likelihood that someone could inadvertently come into contact with the glass, hence the need for safety measures to prevent injuries. This may include the use of tempered or safety glass, which is specially designed to withstand impact and reduce the likelihood of shattering. The other height options are above the designated 60 inches. While they may still be relevant in discussions of glazing and safety, they do not trigger the same level of concern for impact hazards, making them less pertinent in the context of this regulation. Thus, 60 inches is the crucial cutoff point that defines when additional safety considerations must be taken into account for glazing installations in these areas.
