Project of Indoor Air Quality painting

There are many factors to think before beginning a painting project. Special care should be taken when sanding a surface to prepare for painting due to the dust free into the air. The dust may include lead particles, if the surface contains lead-based paint. Exposure to excessive levels of lead could affect a child's mental enlargement, and interfere with nervous system development, which could cause learning disabilities and impaired hearing. In adults, lead can raise blood pressure. Unless a lead-based paint checked to shows it doesn't, you should treat paint in homes built before 1978 as if it contained lead.

Most paints give off volatile organic compounds (VOCs)--chemicals that disappear in the air--that could lead to IAQ(Indoor Air Quality) problems. The ability of these chemicals to cause health effects varies deeply. As with any chemical, the likelihood of a response and the extent and type of health effect will depend on many factors. These factors include the amount of chemical in the indoor air, the length of time a person is exposed to the chemical, and a person's age, pre-existing medical conditions, and individual susceptibility. Eye and throat or lung irritation, headaches, dizziness, and vision problems are among the immediate symptoms that some people have experienced soon after coverage to some chemicals. In professional painters who are exposed to high levels of paint vapors for long periods of time, some chemicals in paints have injured the nervous system, liver, and kidneys. Some chemicals cause cancer or reproductive and developmental special effects in laboratory animals. Because of these concerns, susceptible people, such as young children and individuals with breathing problems, should avoid paint vapors. To avoid any health risks for themselves and their unborn babies, pregnant women should avoid undertaking painting projects and should limit their time in freshly painted rooms, particularly when oil-based paints are being used.
