P2Environmental Tobacco Smoke (ETS) Control
Required To prevent or minimize exposure of tenant space occupants, indoor surfaces and systems to Environment Tobacco Smoke (ETS).
Minimize exposure of non-smokers to ETS by one of the following options:
Locating tenant space in a building that prohibits smoking by all occupants and users and maintains any exterior designated smoking areas at least 25 feet from entries, outdoor air intakes and operable windows OR
In a building that permits smoking, confirming that smoking is prohibited in portions of tenant space not designated as smoking space, in all other building areas served by the same HVAC system, and in the common areas used tenant’s occupants, and that there is no migration of ETS by either mechanical or natural ventilation from other areas of the building AND
When occupants are permitted to smoke, providing one or more designated smoking rooms designed to effectively contain, capture and remove ETS from the building. At a minimum, each smoking room must be:
o Directly exhausted to the outdoors with no recirculation of ETS-containing air to the non-smoking area of a building
o Enclosed impermeable deck to deck partitionso Operated at a negative pressure compared to
surrounding 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) when the doors to the smoking room are closed.
Performance of the smoking rooms differential air pressure shall be verified conducting 15 minutes of measurement with a min 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 rooms closed. The testing will be conducted with each configured for worst case conditions of transport of air from the smoking rooms to adjacent spaces OR

In addition, all doors in the resi units leading to common hallways shall be weather-stripped to minimize air leakage into the hallway. Acceptable sealing of residential units shall be demonstrated by blower doors tests conducted in accordance with ANSI/ASTM standard AND using the progressive sampling methodology defined in Chapter 7 “Home Energy Rating Systems” (HERS).
