When a protective bar 1-1/2 inches wide is installed at a height above the floor, the glazing does not need to be safety glazed. What is that height range?

When a protective bar 1-1/2 inches wide is installed at a height above the floor, the glazing does not need to be safety glazed. What is that height range?

• A. 12"-24"
• B. 24"-34"
• C. 34"-38"
• D. 38"-48"

Answer: (C)

The concept being tested is that safety glazing exemptions exist when a protective barrier shields the glass. If a protective bar, 1-1/2 inches wide, is installed at a height between 34 inches and 38 inches above the floor, the glazing does not need to be safety glazed. The barrier is considered to provide sufficient protection, so the glass is not required to meet safety glazing standards in that specific height range. If the bar is placed outside this range, the glazing would generally still be subject to safety glazing requirements in hazardous locations.
