Question

Which of the following measures are fit for a person on wheelchair?
A. Wide walkways in hallway or doorway
B. Non-slip flooring
C. Space around sofas, beds and tables to move with ease
D. High heights for light switches, door handles and emergency buttons
Choose the correct answer from the options given below:

• A. A, B and D only.
• B. A, C and D only.
• C. B, C and D only.
• D. A, B and C only.

Hint:

For barrier-free design:
- Horizontal spaces (walkways, doors) must be widened (A, C).
- Vertical controls (switches, handles) must be lowered, not raised (D).
Excluding (D) directly points to the correct option.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Barrier-free design (universal design) focuses on creating physical environments that are accessible, safe, and comfortable for all people, including those with physical disabilities or mobility impairments.

Step 2: Detailed Explanation:
Let us evaluate each design measure for a wheelchair user:
- A. Wide walkways in hallway or doorway: Wheelchairs require a minimum width (typically at least \( 32 - 36 \, \text{inches} \)) to pass through doors and turn in hallways comfortably without hitting the walls.
This is a suitable measure.
- B. Non-slip flooring: Wheelchair wheels require adequate traction, and non-slip surfaces prevent slipping, ensuring safety during movement.
This is a suitable measure.
- C. Space around furniture: A wheelchair requires a specific turning radius (usually a \( 60\text{-inch} \) circle) to turn around or change direction, making spacious layouts essential.
This is a suitable measure.
- D. High heights for switches, handles, and buttons: This is incorrect.
A person seated in a wheelchair has a lower reach range.
Placing controls, switches, and handles high makes them inaccessible.
They must be placed at a lower height (typically between \( 36 - 48 \, \text{inches} \) from the floor) so they are within easy reach of a seated person.
Therefore, measures A, B, and C are correct, while D is incorrect.

Step 3: Final Answer:
The suitable measures are A, B and C only.
