If a person is standing outdoors, odds are they can find some sort of clean air to breathe, except in rare cases and in countries like China. When people are indoors however they have no air except the air that is circulating through the building, house, or whatever they may be in. There should be strict standards in order to ensure the air pollution is not at an unsafe level when indoors.
It is a known fact that indoor air pollutants such as smoke, carbon monoxide, mold, particulate matter such as asbestos and vapors from unsafe paints and carpet fibers, cause thousands to sicken each year. Without government oversight regulating and providing monitoring mechanisms for indoor air quality, there would be no protection for unwary consumers
The air we are around every day indoors is very important. If we cannot rely on the air in a facility or a store, then what can we really rely on? We should not have to worry about the air being such a low quality that someone could get hurt from it.
I think that indoor air pollution standards should be strenghtened. I think it is important because a lot of people are usually affected by such thing as second-hand smoke. And when people do not have the rights to not be exposed by it, it can cause problems and issues with their health.
Indoor air pollution standards are a bit more stringent than outdoor standards. This is due to the lack of ventilation, and high possibility of saturation. Typical violations of indoor standards are CO2 and paint fumes. These chemicals can collect fast and injure without much warning. This is why they are already so highly regulated. I don't think there needs to be any additional indoor air pollution standards. Perhaps more enforcement of what is in place would help.
