Sick Building Syndrome!
Article By: Nisha Gopinath, Manager-Administration
All living beings depend on healthy air to breathe, however, atmospheric air also contains certain components called as air pollutants that are harmful to both plants and animals. Outdoor air quality depends on the pollution (and the control measures are taken up) caused by emission from industry, agriculture, and automobiles, while indoor air quality depends on the materials used for the building’s construction and the ventilation systems that limit exposure to various toxic chemicals within the indoor air spaces.
Sick building syndrome describes a situation in which building occupants experience acute health and comfort effects linked to time spent in the building. Most of the complainants report relief soon after leaving the building. The causes of contributing factors to sick building syndrome are inadequate ventilation & chemical contamination from indoor and outdoor sources.
Concentrations of indoor pollutants are often two to five times higher than outdoor concentrations. Indoor air pollution consists of toxic gases or particles that can harm health. These pollutants can build up rapidly indoors to levels much higher than those usually found outdoors. Moreover, “tighter” construction in newer homes can prevent pollutants from escaping to the outdoors. Modern residences contain a staggering variety of synthetic materials from carpets and foam cushions to insulation and chemically treated pressed wood products. These products outgas which means that the chemical compounds they contain break down with age and are slowly released into the air over time in the form of toxic fumes.
The effects of indoor air pollutants range from short-term effects [eye and throat irritation] to long-term effects [respiratory disease and cancer]. Exposure to high levels of some pollutants, such as carbon monoxide, can even result in immediate death. As energy-efficient construction becomes absolutely essential, green building designers have become justifiably concerned about this indoor air quality dilemma. The most effective way to control most indoor air pollutants is to eliminate the source. Improving ventilation by bringing cleaner outdoor air inside can also be beneficial.
ONLY 10% OF COMMON COLD IS CAUGHT OUTDOORS….
90% ARE CAUGHT INDOORS!!!
