ICC Commercial Building Inspector Practice Test

What is the minimum height for glazing in bathrooms to avoid being classified as hazardous?

1. 36 inches

2. 42 inches

3. 48 inches

4. 60 inches

The correct answer is: 60 inches

In commercial building codes, the classification of glazing as hazardous is primarily concerned with the potential for injury due to accidental contact, particularly in areas where individuals have a higher likelihood of falling against or into glass. The minimum height for glazing in bathrooms – which are classified as hazardous locations because they are environments where slips and falls can happen, especially when wet – is established to enhance safety standards. The correct minimum height, which aligns with current code requirements, is established at 60 inches. This height ensures that the risk of a person making contact with the edge of the glazing while standing or slipping is reduced, thereby minimizing potential injury. By specifying a height of 60 inches for non-tempered glazing, codes enforce a higher safety standard in areas where people may be more vulnerable to risks associated with glass. Lower heights could allow for situations where individuals, particularly children or shorter adults, might accidentally strike the glass, increasing the likelihood of serious injury. Therefore, the established height threshold of 60 inches serves as a vital safety precaution in the design and construction of bathroom spaces.
