9. Carbon Monoxide Colorless and odorless Sources: cigarettes, stoves, heaters Binds to Hemoglobin in RBC’s, therefore hemoglobin cannot bind with oxygen

12. Ammonia –Cleaning agents Asbestos –insulation Bacteria, Fungi –Heating and cooling ducts

13. What is Legionaires disease Bacterial disease Inhale the bacteria
