Document Summary

Functions: uniformly distributed animals like consistency, maintain temperature, remove moisture bacteria migrate toward moisture and heat, remove contaminants this is management get gases out of the facility. Cold air is denser than warm air; it sinks to the floor when brought into a warm building. Cold air does not hold very much moisture; as air warms up volume expands and can now absorb more moisture components of air = sulfur dioxide, methane, nitrous oxide, ozone, nitrogen dioxide, iodine, carbon monoxide, ammonia.

Air contaminants: dust particles from bedding, feed, manure, dander. Origin and composition mainly organic animals (skin, hair, feather debris, feces), feed, bedding (plant particles, mold) allergens include mold, pollen, mites. Greater than 10 microns normal defense mechanisms work. Less than 10 microns enters the lower airway. Dust/bioaerosols and health lowers disease resistance causes irritation and inflammation: harbors pathogens concentrates non-pathogenic organisms, absorbs harmful gases.
