[Las Vegas, NV] September 29, 2016: Before investing money in a costly casino ventilation system, it’s worth noting the fine print. The science is clear: HVAC systems do not address the deadly health hazards of secondhand smoke.

If smoking is permitted in any part of the building, everyone inside is affected – from connected retail areas to meeting rooms, not just in the area with the smoking. Limiting smoking to certain rooms or areas of a building do not stop the smoke from spreading. Secondhand smoke is a mix of toxic gases and particulates, and there is no safe level of exposure. Even very lows levels of exposure still have significant health risks especially to the cardiovascular system. The ONLY known way to prevent – or even reduce – the health risks of secondhand smoke is with a 100% smokefree environment.

ASHRAE (American Society for Heating, Refrigeration, and Air Conditioning Engineering) is the organization that develops engineering standards for building ventilation systems. ASHRAE affirms:

  • There is no safe level of exposure to secondhand smoke.
  • Ventilation and other air filtration technologies cannot eliminate the health risks caused by secondhand smoke exposure.
  • Tobacco smoke does not belong in indoor areas.
  • Marijuana smoke should not be allowed indoors.
  • Emissions from electronic smoking devices should not be allowed indoors.
