a) 3 m
b) 1.5 m
c) 1 m
d) 0.8 m

Answer:
The correct answer is option 'B' - 1.5 m.

Explanation:
To understand why the minimum width required for a staircase in an educational building is 1.5 m, let's discuss the factors that determine the minimum width for a staircase.

1. Building Codes and Regulations:
Building codes and regulations vary from country to country and even within regions. These codes specify the minimum requirements for various aspects of a building, including staircases. The minimum width requirement for a staircase is usually determined based on the occupancy type and the number of people expected to use the staircase.

2. Occupancy Type:
Different types of buildings have different occupancy types, which are classified based on the activities conducted in the building. For an educational building, the occupancy type is typically classified as an assembly occupancy. Assembly occupancies include spaces where people gather for educational, religious, or recreational purposes. Due to the larger number of occupants, the width requirements for staircases in assembly occupancies are generally higher than for other types of buildings.

3. Number of Occupants:
The number of occupants in an educational building is typically higher compared to other types of buildings. This is because educational buildings accommodate students, staff, and visitors. The higher number of occupants necessitates wider staircases to ensure safe and efficient evacuation during emergencies.

4. Accessible Design:
Modern building codes also emphasize the importance of accessible design, which includes providing adequate space for individuals with disabilities to use the staircase comfortably. The minimum width requirement for a staircase takes into account the need for wheelchair users or individuals with mobility aids to navigate the stairs without any hindrance.

Conclusion:
Considering the factors discussed above, the minimum width requirement for a staircase in an educational building is 1.5 m. This width allows for the safe and efficient movement of a larger number of occupants, including those with disabilities. It is essential to adhere to building codes and regulations to ensure the safety and accessibility of educational buildings.
