North End Nails Toxic Air

I'm a tennant of 113 Salem st, North End Nails has been venting toxic air into the buildings common area putting all tenants & customers in danger. After being shut down by the board of health multiple times they are now attempting to by-pass all city laws and vent right out there front door onto Salem st. This will directly effect pedestrians simply walking by as well as patrons waiting in line trying to visit local businesses. This place has made many people sick already, it should be stopped now.
