Indoor Air Quality
Indoor air quality is a major concern for a number of industries throughout Australia. From construction and engineering to maintenance teams - air quality testing for carbon monoxide, carbon dioxide and methane must be a serious consideration given the consequences. There have been many incidents in the recent years that highlight the importance of monitoring indoor air quality to protect both building oc - cupations and the environment itself.
What are the consequences of high carbon dioxide measurements?
Carbon dioxide (CO2) is a naturally-produced atmospheric gas which is recorded as parts per million (ppm). Away from heavy traffic areas and industries, the air contains around 380 ppm of CO2. However, humans also expel this gas and in the confined environment of a school or office, and CO2 levels can soon rise.
As office workers and students spend around half their days inside buildings, it is important to maintain adequate indoor air quality. According to several high-profile studies, a primary indicator of indoor air quality is the concentration of CO2. A recorded level above 1,000 ppm is regarded as ‘not ideal’, while the ‘reference range’ should be around 700 to 1,500 ppm. Although a level below 5,000 ppm isn’t going to harm someone’s health, it can have an affect on their mental state.In areas of high CO2 concentration, people report drowsiness, tiredness, lack of concentration and a sense that the air is stale. There is also research to suggest productivity is affected by high CO2 lev - els
What are the consequences of high carbon monoxide measurements?
Carbon monoxide (CO) is an odourless, colourless gas that can cause serious sudden illness and in some instances death. It is pr oduced by a combination of partly-burned gas and Liquid Petroleum Gas (LPG). This is commonly a problem in buildings where a gas appliance is poorly maintained, broken, badly fixed or incorrectly fitted.Carbon monoxide is a real concern for building professionals as a faulty heating system can soon fill a room with the toxic gas.However, if people become sick, it can be difficult to diagnose carbon monoxide poisoning as the cause as the symptoms are similar to a number of other illnesses. This highlights the importance of regular system monitoring and indoor air quality testing.It is recommended that industry professionals check and monitor gas heating systems and related infrastructure on an annual basis. This includes a full maintenance service as well as an in depth CO2 test to determine whether it is emitting gases to a dangerous level.
What are the consequences of high methane measurements?
Methane gas is another colourless and odourless gas that is widely found in the natural environment. However, it is widely encountered by workers in mines and manufacturing as well as being used to heat homes and commer cial buildings. The substance is used extensively in gas stoves, fireplaces and even water heaters. This means it can pose a problem to both workers and the general public if it begins to leak because of often hairline cracks in the pipelines.Ther e are a number of both physical and environmental reasons to detect if you have a methane gas leak. Headaches are a common sign as well as nausea and breathing difficulties. Methane gas is also toxic to vegetation so dead plants near a gas line are a sign of a leak and sometimes a dull hissing or roaring sound can be heard from the gas line itself
