The percentage of U.S. homes with smoke-free rules increased from 43 percent in 1992-1993 to 83 percent in 2010-2011. Over the same period, among households with no cigarette smokers, the national percentage of smoke-free home rules increased from 56.7 percent to 91.4 percent. Among households with one or more adult smokers, the national percentage of smoke-free home rules increased from 9.6 percent to 46.1 percent. Considerable progress has been made increasing the percentage of U.S. households with smoke-free home rules over the past two decades. However, in 2010-2011, fewer than half of all households with smokers had not adopted smoke-free home rules. This is a concern because nearly all nonsmokers who live with someone who smokes inside the home are exposed to secondhand smoke. Exposure to secondhand smoke causes more than 41,000 deaths among nonsmoking adults each year, and causes respiratory problems and SIDS among children.

Laboratory workers and their employers should be familiar with current laboratory biosafety recommendations and ensure that the recommendations are implemented. Nonadherence to established laboratory biosafety recommendations can lead to laboratory-acquired infections among laboratory workers.
