Option 1

Speak directly with your supervisor again, expressing your serious concerns about the safety hazard and the legal/ethical implications of not reporting it, urging them to reconsider.

Option 2

Immediately report the safety hazard and your supervisor's directive to a higher authority, such as HR, senior management, or an external regulatory body like OSHA, without further discussion with your supervisor.

Option 3

Keep quiet about the safety hazard as your supervisor instructed, hoping it will be resolved eventually or that no one will get hurt, and focus on your job duties.
