Explanation:

- Option 1: List of Occupational Hazards

The Factories Act does mention hazards, but the Third Schedule does not specifically provide a list of occupational hazards.

- Option 2: List of Occupational Diseases

The Third Schedule of the Factories Act, 1948, lists specific occupational diseases that are notifiable and for which employers must take action if detected among workers.

- Option 3: List of Notifiable Diseases

While the listed diseases are notifiable under the act, the schedule is formally a list of “occupational diseases”, not simply all notifiable diseases.

- Option 4: List of Industries Involving Hazardous Processes

This is actually covered under the First Schedule, not the Third.

Option 2: List of Occupational Diseases is the correct answer.
