Question

The minimum air space per worker prescribed by Indian Factory (Amendment) Act, 1987 is

• A. 200 cu ft
• B. 300 cu ft
• C. 500 cu ft
• D. 700 cu ft

Hint:

The 1987 amendment fixed worker air space at about 14.2 cubic metres.

Answer 1

The Correct Option is C

Step 1: Know what the law is protecting.
Factories must give each worker enough room to breathe clean air and avoid crowding, so the law sets a minimum floor to ceiling volume per head.

Step 2: Recall the fixed number.
The Factories (Amendment) Act, 1987 set this at 14.2 cubic metres per worker, which converts to close to 500 cubic feet.

Step 3: Note the height rule.
Only space up to 4.2 metres above the floor counts toward this volume, so very tall rooms do not get credit for the extra height.

Step 4: Eliminate the other numbers.
200, 300 and 700 cubic feet do not match the legally fixed figure, so only 500 cubic feet is right.

Step 5: Conclude.
\[ \boxed{500 \text{ cu ft}} \]
