How to Conduct Testing for Cigarette Smoke in Your Multi-Family Building
Cigarette smoke can present a challenging odor problem in multi-family buildings, including environmental tobacco smoke (ETS), secondhand smoke (smoke exhaled by smokers or emitted from a lit cigarette), and thirdhand smoke (lingering cigarette odors absorbed and released by various surfaces and materials). While the adverse health effects of smoking are well-documented, ETS exposure can lead to its own set of acute and chronic health issues for non-smokers.
Short-term effects of ETS include asthma triggers, eye and respiratory irritation, and hoarseness, while long-term exposure has been linked to asthma development and is the second leading cause of lung cancer in non-smokers. In a multi-family setting, you have limited control over your neighbors' actions, and due to the complex airflow dynamics within a building, you may encounter cigarette smoke odors in your unit even if you've never smoked indoors. So, how can you confirm the presence of ETS?
Testing for ETS can be challenging, as cigarette smoke consists of numerous chemicals and particulate matter. Laboratories attempt to detect it using "indicator compounds" that are unique to cigarette smoke and not commonly found in indoor environments. However, it's worth noting that human noses are often more sensitive to cigarette smoke odor than current laboratory tests, and the smell alone doesn't always correlate with laboratory results.
One testing method involves taking wipe samples from hard surfaces in areas with tobacco smoke odors. These samples are then analyzed for nicotine, a common marker of ETS. Notably, not all surfaces in such areas will have detectable nicotine levels, with surfaces closer to recent smoking activities being more likely to test positive.
Another approach is to monitor particulate matter levels and maintain an odor log. This method allows for a longer observation period compared to laboratory tests, making it suitable for situations where the odor pattern is unpredictable.
It's important to remember that controlling cigarette smoke from entering your unit can be as challenging as testing for it. Each project is unique, and depending on the circumstances, multiple testing methods may be necessary to document cigarette odors in your home. If you're dealing with cigarette smoke issues in your home, consider contacting professionals who can provide guidance and solutions tailored to your specific situation.
Living in a multi-unit building with a smoking neighbor can be a source of frustration. Secondhand smoke from such neighbors can lead to immediate health issues like asthma exacerbation, eye and respiratory irritation, and hoarseness. Furthermore, prolonged exposure to secondhand smoke has been linked to the development of lung cancer. This situation becomes even more vexing if your neighbor is violating building regulations by smoking indoors.
To address this problem, you may want to explore methods for detecting and providing evidence of the smoke violation. However, it's important to be aware of potential challenges and pitfalls in gathering proof.
When polite requests to your neighbor and communication with building management prove ineffective in resolving the issue, it may become necessary to take matters into your own hands.
We recommend initiating the process with air and wipe tests specifically designed to detect nicotine presence. This evidence can substantiate the claim that your property is adversely affected by your neighbor's smoking habit. An indoor air quality consultant can assist in collecting an air sample using a thermal desorption tube, aiming to identify the presence of environmental tobacco smoke (ETS). This specialized test assesses three key ETS markers: 2,5-dimethylfuran, 3-Ethenylpyridine, and nicotine. The identification of any of these compounds at any level serves as analytical confirmation that ETS is infiltrating your unit. In addition, a wipe test can further verify the presence of nicotine on the surfaces within your property.
What other factors can influence the test results?
Is your neighbor smoking on their porch or indoors? If it's outdoors, the smoke is likely to disperse into the surrounding air, making it challenging to obtain accurate readings. On the other hand, if they smoke indoors, it's crucial to identify whether the strongest odor is in the ceiling plenum or within the ductwork. Additionally, consider whether furnaces or air conditioners are in operation, as this can influence the circulation of air and odors within the building. In such cases, providing the consultant with information about where the odors are most pronounced and the prevailing conditions is essential.
If the suspected smoker resides next door, the consultant may employ a method involving the opening of an electrical outlet cover and placing the testing tube in proximity to the open wall. This technique requires precise timing but can yield successful results by detecting whether smoke is accumulating within the wall cavity.
It's worth noting that factors like wind speeds and building pressurization can also impact test results. Engaging a qualified indoor air quality consultant, such as Indoor Science, can significantly enhance the likelihood of success. In many cases, obtaining concrete evidence may be sufficient to persuade your neighbor to cease smoking in areas that affect your living space.
Testing can indeed be a bit tricky!
For air sampling to yield the most reliable results, it's crucial that your neighbor is actively smoking during the designated two-hour testing period. In cases where your neighbor refrains from smoking during the test, the outcomes may end up inconclusive. Surprisingly, many of my clients find it helpful to maintain a written log that documents when their neighbor smokes.
Given that humans tend to follow routines, this log serves as a valuable tool for scheduling the testing appointment strategically. If you're aware that your neighbor typically smokes on specific days and times, such as Mondays, Tuesdays, and Fridays between 10:00 AM and 11:30 AM, this information can assist the indoor air quality (IAQ) consultant in optimizing the timing of the tests.
