IICRC Odor Control Technician (OCT) Practice Exam

The recommended initial procedure for removing environmental tobacco smoke involves washing surfaces. This step is crucial because nicotine and other components of tobacco smoke can adhere to various surfaces, such as walls, furniture, and upholstery, creating an ongoing odor issue. Cleaning these surfaces with appropriate cleaning solutions can effectively remove the smoke residue and reduce the source of the odor. While vacuuming surfaces may help to remove particulates, it does not adequately address the chemical components of tobacco smoke. Air purifiers can assist in improving air quality by filtering out airborne particles, but they may not eliminate odors that are absorbed into materials. Spraying odor neutralizers might provide a temporary masking effect, but it does not tackle the underlying issue of smoke residue. Therefore, washing surfaces is the most effective initial step in eliminating the source of environmental tobacco smoke odors, helping to ensure a more thorough and lasting resolution to the problem.
