		Indoor air pollution is one risk that you can do something about.
		Indoor air quality (IAQ) is a critically important aspect of creating and maintaining school facilities.
		The mission of the Partnership is to improve health, livelihood, and quality of life by reducing exposure to air pollution, primarily among women and children, from household energy use.

	Indoor air quality - Wikipedia, the free encyclopedia
		One of the most acutely toxic indoor air contaminants is carbon monoxide (CO), a colorless, odorless gas that is a byproduct of incomplete combustion of fossil fuels.
		Indoor levels are an indicator of the adequacy of outdoor air ventilation relative to indoor occupant density.
		NIOSH considers that indoor air concentrations of carbon dioxide that exceed 1,000 ppm are a marker suggesting inadequate ventilation (1,000 ppm equals 0.1%).

	Indoor Air Quality and Health Fact Sheet
		Indoor sources of contaminants include cigarette smoke, renovation and remodeling materials, dirt, deteriorating lining in the ventilation system itself, cleaning compounds, materials that are used inside such as white-out, copy machines, laser printers, pesticides, etc. Outdoor sources include car exhaust, pollen, and industrial emissions from nearby buildings.
		Air that is too humid, RH greater than 60%, may cause moisture to form and mold to grow.
		The air is transported to all the rooms through the ductwork and blown into each room through the diffusers to both ventilate and maintain the desired temperature.

	Air Quality Program
		The goal of the Air Quality Program is to maintain air quality levels in South Dakota that protect human health, safety and welfare and the National Ambient Air Quality Standards established through the Federal Clean Air Act.
		Once an air quality problem is identified, it is addressed by the rulemaking process, permitting process, or outside of the regulatory process.
		The most typical air quality problems and complaints are associated with open burning and fugitive dust.

	Indoor Air Quality
		The first way to help clean the air in your home is by allowing the air to be filtered as it passes through the air mover of your heating and air conditioning system.
		Air filters have different costs, and they have widely different efficiencies in their ability to filter the air.
		An air conditioning system with a variable drive blower can be set up to recognize this high humidity condition and to help relieve it without over cooling your home to an uncomfortably low temperature.

	Safety and Health Topics: Indoor Air Quality
		Concerns with indoor air quality (IAQ) have increased since energy conservation measures were instituted in office buildings during the 1970s, minimizing the infiltration of outside air and contributing to the buildup of indoor air contaminants.
		IAQ generally refers to the quality of the air in an office environment.
		Complaints about IAQ range from simple complaints, such as the air smelling odd, to more complex, where the air quality causes illness and lost work time.

		This established the baselines and has included periodic inspections to ensure that indoor air quality goals continue to be achieved in the months and years to come.
		The design outdoor air quality requirement for the ERC is 20 cubic feet/minute/person, which is in line with ASHRAE Standard 62, and equates to 800 ppm carbon dioxide assuming an occupancy level of 142 square feet/person.

	Indoor Air Quality
		The quality of the air in your home can impact your health or the health of those you live with.
		Indoor air pollution can be a real concern because people can spend as much as 90% of their time indoors, and much of that time is in their homes.
		One way to determine whether you have an indoor air quality problem is to look at how you or those in your household feel when home.

		Poor indoor air quality can cause or contribute to the development of chronic respiratory ailments such as asthma and hypersensitivity pneumonitis which is an inflammation of the lungs caused by an allergic reaction or virus.
		However, how effective an air cleaner is depends on how well it traps the pollutants from the indoor air, which is expressed as a percentage efficiency rate, and how much air it draws through its cleaning or filtering unit, which is expressed as cubic feet per minute.

	PEOSH Indoor Air Quality
		Because of this and increased awareness regarding poor indoor air quality (IAQ), it is not surprising that the number of reported employee complaints of discomfort and illness in nonindustrial workplaces is increasing.
		Investigating IAQ complaints, however, can be very complicated due to employee concerns, unknown sources of contamination, and the complexities of buildings and their ventilation systems.
		To achieve acceptable IAQ, outdoor air should be adequately distributed to all office areas at a minimum rate of 20 cubic feet per minute (cfm) per person OR the concentration of all known contaminants of concern be restricted to some specified acceptable levels as identified in ASHRAE's "Ventiliation for Acceptable Indoor Air Quality" Standard.

		As fresh air flow is reduced, the natural removal of contaminants from the air also diminishes, leading to sick building syndrome, a condition characterized by a build up of contaminants in indoor air.
		When occupants of buildings begin to complain of persistent or reoccurring headaches, irritation of the upper respiratory tract, eye irritation, and/or general discomfort, a study of the quality of the air in the building is recommended.
		Potential indoor air problems and their sources can be identified through the use of questionnaires, evaluations, chemical testing and ventilation system inspections.

		If the air pressure is lower indoors than in the soil, air and gases in the soil will enter.
		Since air pressure is higher in the house, soil gas moves to the exhaust pipe rather than into the house.
		All of these suggestions are directly related to controlling air leakage in the house, because the faster the air leaks out of the house, the more it inducts radon by increasing negative pressure in the bottom of the house.

	Indoor Air Quality
		Most often, unfavorable air quality is the result of mold and fungal growth, volatile organic compounds (VOCs) from cleaning or maintenance procedures, air intake contamination from vehicles, maintenance operations such as snow removal equipment or from exhaust air being blown back in to the air intake, and lack of adequate air exchanges.
		The fact is that IAQ problems are hard to track down due to the variety of potential sources and the inconsistencies of when the problem occurs on a day to day basis.
		The ability of air to hold water decreases as the temperature is lowered, hence outside air has less humidity in the winter than it does in the summer.
