Failing to properly vent fumes from a home using appropriate flue accessories could result in a number of health problems.
The most recent best practice guide from the Residential Ventilation Association (RVA) indicates that even single exposure to air pollutants in the home can be problematic.
Irritation of the eyes, throat and nose are among the most common, immediate problems following exposure to harmful gases such as carbon monoxide, or substances in smoke, including soot.
Headaches, dizziness and fatigue are common symptoms, although these are usually short-term and treatable, notes the RVA.
However, other health issues may not be apparent until years after exposure. Respiratory diseases, heart disease and even cancer can all cause problems.
As such, the RVA advises that attempts are made to improve air quality if any of these symptoms become apparent.
Evaluation of heating, ventilation and air conditioning is often a good place to start, allowing for further measurement of contamination levels for particular substances.
