What is the penalty for a first offense in Category B?

The penalty for a first offense in Category B is indeed set at $500. This figure represents the established fine intended to address minor transgressions that fall within this classification. Category B typically encompasses violations that are not considered severe but still warrant financial penalties to encourage compliance and uphold industry standards.

The amount is designed to serve both as a deterrent and a means of reinforcing the importance of adhering to regulatory guidelines. The penalties increase in severity for repeated offenses, which underscores the regulatory body's commitment to maintaining a high standard of practice in the commercial inspection field.

In the context of other choices, while suspensions may apply for more severe or repeated violations, they do not pertain to first offenses in Category B, thus making them irrelevant in this situation. Similarly, lower fines would not adequately reflect the established penalty framework for such offenses.
