MS HB54

Creates the Mississippi Smoke-free Air Act of 2010 to prohibit smoking in all enclosed public places, enclosed workplace facilities, and certain outdoor areas to protect public health from secondhand smoke exposure.

Bans smoking in enclosed public places including bars, restaurants, health care facilities, educational institutions, retail stores, transportation facilities, and gaming establishments, with limited exemptions for private clubs without employees and up to 20% of hotel/motel rooms.

Prohibits smoking in all enclosed workplace facilities without exception, including work areas, offices, vehicles, cafeterias, and restrooms, requiring employers to notify employees by August 1, 2010.

Establishes outdoor smoking prohibitions within 20 feet of building entrances, windows, and ventilation systems; in restaurant outdoor seating areas; and in sports arenas and service lines, with designated smoking areas allowed only in perimeter zones.

Sets penalties for violations as misdemeanors with fines up to $50 for individuals smoking in prohibited areas and $100-$500 for owners/operators failing to comply, with authority for local health departments, city/county administrators, and private citizens to enforce the act.
