How many occupation classes are there in this insurance framework?

In the context of Accident and Sickness Insurance, the classification of occupations is critical for determining the level of risk and, consequently, the premium rates for insurance coverage. The insurance industry typically distinguishes between three occupation classes:

1. Class 1: This includes individuals in low-risk occupations, such as office workers or those in the service sector where physical risk is minimal.

2. Class 2: This category encompasses medium-risk occupations, which may involve some physical labor or exposure to moderate risk factors, such as tradespeople or construction workers, depending on their specific duties.

3. Class 3: This class covers high-risk occupations where the probability of accidents or health issues is significantly greater, such as those in industries involving heavy machinery, hazardous materials, or jobs that demand high physical exertion.

Understanding these three classes helps insurers appropriately assess risk levels and design coverage accordingly, ensuring that premiums are reflective of the potential claims that could arise from each job's inherent risks.
