In terms of requirements for height, which option is compliant for a roof access?

14 feet
15 feet
16 feet
20 feet

The correct answer is: 15 feet

The requirement for roof access height typically correlates with safety and accessibility standards set by various building codes and regulations. In this context, a height of 15 feet is often recognized as compliant for roof access. This standard is established to ensure that workers can safely perform maintenance or inspections without excessive risk. Heights greater than 15 feet may require additional safety measures, such as guardrails or safety systems, to prevent falls and ensure that workers have the necessary training to access these areas safely. Therefore, the 15-foot requirement strikes a balance between being accessible and maintaining a focus on safety protocols for personnel working at elevated levels. This is part of why this particular height is seen as compliant in many jurisdictions. Other options, such as 14 feet, typically do not meet the threshold established for safe access, while heights like 16 feet and 20 feet often necessitate more stringent regulations regarding safety equipment and training, thus making the 15-foot option more practical within the standard compliance parameters.
