Supply waterproof mats and walk-off mats over carpeted entryways and other areas used for drying clothing and umbrellas. Standards and Guidelines for Indoor Air Quality: Many office buildings and areas of public assembly have banned smoking indoors, or required specially designated smoking areas with dedicated ventilation systems be available. Concentrations of indoor air pollutants typically vary greatly over time, and the specific contaminant measured may not be causing the problem. 1-866-627-6767, Adhesive and Sealant Council IAQ investigators often find a large number of potential sources contributing low levels of various contaminants to the air. Nonetheless, your efforts may not have noticeably reduced the concentration of the contaminant or improved ventilation rates or efficiency. Fixing plumbing leaks and other unwanted sources of water. The school administration believes that an independent investigation would be better received or more effectively documented than an in-house investigation. Health-related concerns associated with portable classrooms have arisen. Step 5: Set thresholds for taking action. If the cause (or causes) of the IAQ problem has already been identified, proceed to the solution phase outlined in Section 6: "Solving IAQ problems.".
