Spanish regulations, like those of other countries, lay down various criteria for the permanent ventilation opening which must exist in premises containing gaspowered domestic food cookers. There is growing concern as to the effects of NOx on the health of weaker people such as children old people and those suffering from respiratory ailments, who spend most time at home.
Domestic gas apparatus generate oxides of nitrogen (NOx), which have been classed in recent years as problem products in the context of indoor air quality (IAQ). These, together with carbon monoxide which may also be present in the products of gas combustion, mean that the formulation of regulations for health protection presents complex problems. The present work shows the importance of this matter and presents interesting case studies taken from the Basque Country and our area of influence. It also makes specific recommendations as to how existing regulations should be changed.
