What is the minimum height required for a guardrail on a roof in a commercial building?
900 mm
1000 mm
1100 mm
1200 mm
The correct answer is: 900 mm
The minimum height required for a guardrail on a roof in a commercial building is 900 mm. This is because it is the industry standard for safety and recommended by most building codes and regulations. Option B, C, and D are all incorrect as they suggest a greater height requirement, which may make it difficult for workers to access the roof or for equipment to be moved onto it.
