|
Definition
Indoor air quality is an important aspect of human health because 90% of our time is spent indoors.

Term
| Why do institutional environments present potential hazards to those working, living or admitted to them? Be able to name and briefly describe five of the common problems associated with institutional environments. |
|
Definition
Institutional environments present potential hazards for those working living or admitted into them because they are small communities that have frequent opportunities for the spread of disease.
• Highly stressed/overworked employees.
• At risk individuals for infection due to weakened biological systems.
• Frequent opportunity for disease transmission
• Invasive procedures on the body
• There is also the problems involving common air, waste and food handling, hazardous chemicals and equipment sharps, and blood borne pathogens. |
