What is the function of a guard in construction?

A guard in construction primarily serves the function of providing safety at elevated areas. This includes installations such as guardrails, which are designed to prevent falls from heights, ensuring the safety of individuals working or passing by elevated surfaces. These safety measures are critical in areas like stairways, balconies, rooftops, and any other locations where there is a risk of falling.

The importance of guards is particularly emphasized in construction and building codes, which set requirements to minimize hazards associated with height. Their proper installation and maintenance are essential for reducing the risk of injury, thereby highlighting the significance of safety in construction practices. While guards do not directly contribute to thermal efficiency, aesthetic enhancements, or structural load-bearing, their role in safeguarding individuals is paramount, making this function the primary reason for their existence in construction contexts.
