What is the minimum height required for a guardrail on a ramp in a residential building?

900 mm
1000 mm
1100 mm
1200 mm

The correct answer is: 1000 mm

A guardrail is an essential safety feature for any elevated structure, such as a ramp, in order to prevent falls and accidents. Of the given options, the minimum height required for a guardrail on a ramp in a residential building is 1000 mm. Option A (900 mm) may not be high enough to properly protect individuals from falling off the ramp. Option C (1100 mm) and D (1200 mm) may be unnecessarily high and could create difficulty for people with mobility challenges to ascend and descend the ramp with ease. Therefore, B (1000 mm) is the most appropriate and safe option for the minimum height of a guardrail on a ramp in a residential building.
