What is an Indoor Air Quality Assessment Checklist?

An indoor air quality assessment checklist is a tool used by building managers, facility managers, homeowners, employers, and environmental health professionals and inspectors to evaluate the quality of the air inside buildings or other enclosed spaces. It includes a series of questions and tasks to identify potential sources of indoor air pollutants, assess overall air quality, and ensure a safe and healthy indoor environment.

Hence, it’s important to check and comply with laws and regulations related to indoor air quality that are specific to regions or countries.

It’s also essential to note that inadequate air quality assessments, ventilation, and prolonged exposure to indoor air pollutants can lead to a range of health problems such as the following:

  • Respiratory Irritation and Infections (caused by dust, pollen, mold spores, and pet dander)
  • Allergies
  • Asthma Exacerbation
  • Eye Irritation
  • Skin Irritation
  • Fatigue and Headaches
  • Volatile Organic Compounds (VOCs)
  • Cardiovascular Effects
  • Aggravation of Chronic Conditions
  • Sick Building Syndrome (SBS)
  • Reduced Cognitive Function
  • Long-Term Health Risks
  • Impact on Vulnerable Populations
  • Decreased Quality of Life
