Question

Some of the engineering measures which should be considered for prevention of occupational diseases:
A. Maintenance and analysis of health records
B. General ventilation
C. Building design
D. Health education and counselling
E. Protective Devices
Choose the correct answer from the options given below:

• A. A and D Only
• B. A, D and C Only
• C. B, C and E Only
• D. C, D and E Only

Hint:

Engineering controls = Modify environment (ventilation, design, safety devices)

Answer 1

The Correct Option is C

Concept:
Engineering measures are physical or mechanical modifications in the workplace environment designed to reduce exposure to hazards.

Step 1: General ventilation.

• Improves air quality and reduces airborne contaminants Thus: \[ B: Correct \]

Step 2: Building design.

• Proper layout, spacing, and ergonomic design reduce occupational risks Thus: \[ C: Correct \]

Step 3: Protective devices.

• Includes masks, guards, shielding mechanisms Thus: \[ E: Correct \]

Step 4: Non-engineering measures.

• A: Health records → administrative measure
• D: Health education → behavioral/preventive measure

Step 5: Final conclusion.
\[ \boxed{\text{Correct answer = Option (3)}} \]
