Final Answer:
Staircases with more than 7 stairs must have a guardrail. (option C)
Step-by-step explanation:
Staircases with more than ₇ stairs must have a guardrail. This safety requirement is established to prevent accidents and ensure the well-being of individuals using the staircase. The implementation of guardrails becomes crucial as the number of stairs increases, providing support and protection against falls.
The specific threshold of ₇ stairs is determined by safety standards and regulations, taking into account factors such as the height of the staircase, the potential risk of falling, and the need for stability during ascent or descent. Guardrails play a vital role in minimizing the risk of accidents, especially in settings where stairs are a prominent feature, such as residential buildings, offices, and public spaces.
Ensuring compliance with guardrail regulations contributes to overall building safety and accessibility. The requirement acknowledges the increased potential for accidents as staircases become longer, emphasizing the importance of structural features that enhance stability and prevent falls. This attention to safety standards is integral to architectural and construction practices, prioritizing the well-being of occupants and users of various structures.(option C)
