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

1. 900 mm

2. 1000 mm

3. 1100 mm

4. 1200 mm

The correct answer is: 1000 mm

The minimum height required for a guardrail on a ramp in a residential building is 1000 mm, which is answer B. This is the standard height recommended by building codes for safety reasons. Option A, 900 mm, is too low and may not provide adequate protection for people using the ramp. Option C, 1100 mm, and Option D, 1200 mm, are both too high and may impede movement and accessibility for individuals with mobility aids or disabilities. It is important to follow the recommended height requirements to ensure the safety and accessibility of all individuals using the ramp. Additionally, the specific height requirement may vary depending on local building codes, so it is important to check with your local authorities for the exact measurement.
