As per National Building Code of India, 2005, the maximum number of occupants per unit exit width of a doorway is 60, where unit exit width is 500 mm. The maximum permissible occupants in a theatre having four number of 2.2 m wide doors will be _________________
-
- 480 to 760
- 360 to 560
- 960 to 960
- None of the above
Correct Option: C
Unit exit width is 500 mm (0.5 m). In the problem, door width is 2.2 m.
Thus, effective width of door as per unit standards need to be considered as 2.0 m instead of actual width 2.2 m.
| Thus, maximum number of occupants per door of 2 m width = |  |  | × 60 = 240 | ||
| 0.5 |
Thus, maximum number of occupants in a theatre with 4 doors = 240 × 4 = 960.
