Absolutely. OSHA & EPA routinely fine small companies with less than 10 employees.
Unfortunately the answer is "yes" in cases where company leadership are aware of hazards or major risks, but fail to action which results in fatalities or serious damage to the environment.
The average failed OSHA inspection will cost a company between $35,000 - $90,000, but can exceed $100,000 or more in many cases. EPA and state environmental fines can also run into the $10s or $100s of thousands of dollars because they're not capped, and fines can be issued for every day that the company was out of compliance. COULD YOUR COMPANY AFFORD THIS?
