At what minimum angle, from horizontal, must the top leading edge of tempered glass doors be tapered to avoid the 10 inch bottom requirement?

1. 45

2. 60

3. 75

4. 90

The correct answer is: 60

The correct answer is 60 degrees because this angle is significant in ensuring that the leading edge of the tempered glass door does not create a hazard when the door is installed. Tapering the top leading edge at a 60-degree angle from the horizontal means that it will be less likely to cause injury or impact against the door's edge, which is crucial for safety in building code regulations. In terms of building codes, the requirement to taper the edge is implemented to reduce the risk of sharp edges that could potentially cause injury. When the leading edge is tapered at this angle, it allows for a smoother transition and helps in adhering to the safety standards set forth by the code, effectively avoiding the need for the 10-inch bottom requirement. Other angles, such as 45 degrees or 90 degrees, would not provide the same level of safety due to their sharper or more vertical nature, which could increase the risk of injury. Therefore, the 60-degree taper is both practical for building design and conforms to safety regulations aimed at preventing accidents.
