Environmental tobacco smoke (ETS) control

EQp2 | Required


Minimize exposure of building occupants, indoor surfaces, and ventilation air distribution systems to Environmental Tobacco Smoke (ETS).


Option 1
  • Prohibit smoking in the building.
  • Locate any exterior designated smoking areas at least 25 feet away from entries, outdoor air intakes and operable windows.
Option 2
  • Prohibit smoking in the building except in designated smoking areas.
  • Locate any exterior designated smoking areas at least 25 feet away from entries, outdoor air intakes and operable windows.
  • Locate designated smoking rooms to effectively contain, capture and remove ETS from the building. At a minimum, the smoking room must be directly exhausted to the outdoors with no re-circulation of ETS-containing air to the non-smoking area of the building, and enclosed with impermeable deck-to-deck partitions. With the doors to the smoking room closed, operate exhaust sufficient to create a negative pressure with respect to the adjacent spaces of at least an average of 5 Pa (0.02 inches of water gauge) and with a minimum of 1 Pa (0.004 inches of water gauge).
  • Performance of the smoking room differential air pressures shall be verified by conducting 15 minutes of measurement, with a minimum of one measurement every 10 seconds, of the differential pressure in the smoking room with respect to each adjacent area and in each adjacent vertical chase with the doors to the smoking room closed. The testing will be conducted with each space configured for worst case conditions of transport of air from the smoking rooms to adjacent spaces with the smoking rooms’ doors closed to the adjacent spaces.
