Roommates Lighting Fireplace Despite Failed Fire Inspection (usa). What Should I Do?

My three roommates insist on some majority wins on using our fireplace despite the fact that we failed fire inspection. Call me paranoid but we are renting in a pretty expensive townhouse. God forbid our place caught fire, it could easily cost millions in property damage including neighboring houses. Looking online it seems like even if I get renters insurance it would be voided for failing inspection and knowingly using the fireplace.

I am on the cusp of studying abroad. After this month I will be gone 6 months. What should I do here? Im assuming notifying the landlord will bite me with a rent increase, or nightmare roommates.
