Indoor Air Quality Audit Parameters
1. Temperature and Humidity
Harmful Effects: Microbiological growth, sweating at normal temperature, skin irritation, eye dryness.
2. Respirable Suspended Particulate Matter (RSPM) or PM (Particulate Matter)
RSPM / PM is tiny pieces of extremely fine liquids & solids that get mixed in air that we inhale. The smaller the PM, the more harmful it is; it then gets deeper into our lungs and even into our bloodstream and cause great damage to our body and system. The particulate matters are classified on the basis of their size.
3. Carbon Dioxide (CO2)
4. Volatile Organic Compounds (VOCs)
5. Formaldehyde (CH2O)
CH2O gas is colourless flammable and highly reactive at room temperature. Formaldehyde poses a great health threat because of the out gassing that occurs in new products and persists for many years. Formaldehyde settles in small cavities within the products. Over time the harmful vapours are discharged into the air. Formaldehyde irritates the mucous membranes of human beings, and high concentrations are intolerable.
6. Ozone (O3)
7. Carbon Monoxide (CO)
