How far must a ladder extend above the roof landing?

24 inches
30 inches
36 inches
48 inches

The correct answer is: 36 inches

A ladder must extend at least 36 inches above the roof landing to ensure safe and reliable access. This height provides sufficient handhold for users when transitioning on and off the ladder, which is crucial for maintaining balance and stability while accessing the roof or descending back down. Extending the ladder by this amount helps to reduce the risk of accidents by offering extra support and allows the user to securely grab onto the ladder while they maneuver. Safety regulations often specify this measurement as a standard practice in order to minimize the risk of falls and to ensure that personnel can safely reach elevated work areas. Other options, while they may seem reasonable, do not meet the required height for safe access and exit on rooftops, making 36 inches the only value that ensures both compliance with safety standards and practical usability.
