Adequate ventilation and good air distribution are important.
In our cities, the air we breathe is not clean. Coal plants and factories belch out harmful CO2, trucks and cars spew filthy exhaust fumes. Many families in our cities rely on coal and wood fires for heating and cooking. On the outskirts of the city, cows and other farm animals add methane to the mix. Sometimes just looking out your window at all the pollution may be enough to make you stay indoors.
Staying indoors
The degradation ofindoor air quality can be worse than outdoor pollution. Pollutants can build up more in the much smaller closed-up area of your home. They may not be ventilated to the outside.
You may think indoor air pollution does not apply to you. In addition, you don’t live near a highway, farm or industrial plant. You don’t smoke and you don’t use a wood-burning stove. However, the air you breathe may still be polluted.
Some very surprising sources cause indoor air pollution:
Your house itself.
The land on which your house is constructed.
Furthermore, we spend a large portion of our time indoors. Indoor pollution can then becomes a serious concern.
Side effects of air pollution
Some side effects of indoor pollution is maybe a little worse than the common cold. However, pollution can lead to coma, lung cancer and death if you are exposed over a long period. Continue reading “Air Pollution in Your Home”
Many homeowners have installed gas appliances due to high electricity costs. However, homeowners must comply with specific regulations which relate to safe installations, Gas Certificates of Conformity and South African National Standards.
Appliances must conform to the relevant SABS standard (SANS 1539).
As from 2009, the Occupation Health and Safety Act (No 85 of 1993) requires that all gas installations must have a Gas Certificate of Conformity! This applies to all permanent installations such as gas fires, hobs, stoves and braais. After an installation has been inspected a Gas CoC is issued if it is safe and leak-free.
Authorised installers registered with the Liquefied Petroleum Gas Safety Association of Southern Africa (LPGSASA) issue certificates.
Any homeowner who has a liquefied petroleum gas (LPGas) appliance installed in their home must have this certificate.
Home insurance
Gas appliances that leak could have major health implications for a family. Not to mention the huge danger of an explosion.
If you don’t have this gas certificate an insurance company will repudiate claims. This could have severe financial repercussions for you. Such an inspection is essential for your insurance policy to remain valid. Moreover, an inspection will ensure that the installation is safe and your family is not at risk.
When you sell your home. you are required to hand over the gas certificate to the new purchaser.
Safety service checks
If you smell gas or suspect your gas appliance is leaking turn off the appliance immediately. In addition, open all the doors and windows to air the room and shut off the gas supply at the control valve. Before you use it again, have it checked by a registered gas installer.
Have a registered gas installer perform an annual service check to ensure your gas installations remain in working order. Go to either the LPGSASA website or the SAQCCGAS websitefor a list of registered gas installers near you.

Staying indoors
Pollutants can build up more in the closed much smaller areas of your home than in open areas because they may not be released to the outside. As a result, the degradation of indoor air quality can be worse than outdoor air pollution.
You may think indoor air pollution does not apply to you. Furthermore, you do not live near a highway, farm or industrial plant. You do not smoke and you do not use a wood-burning stove. However, the air you breathe may still be polluted.

The land on which your house is constructed.
In addition, most people spend a large portion of their time indoors. Indoor pollution can then become a serious concern.
Side effects of pollution
Some side effects of indoor air pollution may be a little worse than the common cold. But, long-term exposure can lead to coma, lung cancer and death.
The likelihood is that you encounter at least one harmful chemical in your home every day. Even if this is not the case you may not yet be safe, e.g. using spray paint indoors can release high levels of air pollutants in a very short time.
For instance, chemicals leaching out of your carpet will, over time, severely affect the air quality.
Listed below are some most common causes of indoor air pollution:
Cigarette smoke
Cigarette smoke carries many toxins. It remains within contained spaces and can cause many medical problems for humans and pets. If you or someone in your family smokes do it outside the home to avoid pollution of the air inside your home.
Biological contaminants
Biological contaminants include bacteria, mould, mildew, viruses, animal dander, dust mites, cockroaches and pollen. Many of these are carried into the house or grow in damp, warm environments. When you don’t open windows and doors after using showers and baths mould will form on walls and ceilings. Furthermore, prevent condensation of windows and walls in your bedroom by keeping a window open while you sleep.
Combustion
Unvented gas heaters, woodstoves, fireplaces and gas stoves emit carbon monoxide, nitrogen dioxide and small particles. Therefore, be careful when using solid fuels like wood and coal for heating and cooking. Make sure the room or house is well-ventilated.
Household products
Paint, varnishes, hobby products, air fresheners and cleaning products release organic chemicals causing pollution in indoor air. Therefore, be careful with their use and storage.
Pesticides
Furthermore, up to 80% of exposure to pesticides happens indoors. Many homes have pesticides in indoor air at measurable levels. In addition, the potential harm from pollutants is dependent on individual sensitivity. Older people, the young and those with compromised immune systems are more susceptible.
Therefore, ventilation plays an important role in air quality and how these pollutants harm you. If fresh air frequently circulates throughout the area, pesticides won’t accumulate and reach dangerous levels. Open windows and doors when the weather is nice, and especially after a lightning storm when the air is cleaner to get rid of the pollution in the indoor air!
