In addition to fines, what other penalty may occur if a business does not follow workplace safety laws?

The closure of a business is a possible penalty for non-compliance with workplace safety laws. When a business violates these regulations, especially if the violations are severe or repeated, regulatory agencies may take significant action to protect workers and the public. This can include shutting down the operation until the issues are resolved or, in extreme cases, permanently revoking the business's license to operate.

The other options presented do not align with the typical repercussions of failing to adhere to safety laws. Increased profit margins and an expanded workforce would generally be the result of effective and compliant business practices, not penalties. Similarly, government grants are usually offered to support businesses that comply with laws and regulations, rather than as a consequence for non-compliance. Thus, the correct choice reflects the serious consequences that can arise from not following workplace safety laws.
