In many cases, such action will entail triggering an ancillary device3.10warm-up timethe time interval between the time when the apparatus is switched on and the time when theapparatus is fully operationalSIST EN 50292:2002

- 7 -EN 50292:2001Flue reversal may occur under certain climatic conditions with appliances using combustionair taken from within the premises. This is a temporary phenomenon which may occur withcertain types of appliance, even when correctly maintained.4.3.1 Space and water heatingSolid, liquid and gaseous fuels may be used for space and water heating. They are used ina variety of ways, either as a local heat source or a remote central heat source, including: appliance with flue using room air; appliance without flue using room air; appliance with flue using external air.In defective warm air systems, carbon monoxide may be distributed into remote rooms.4.3.2 CookingNatural gas, town gas or LPG are the main fuels for cooking, generally using unfluedappliances.
In some cases, solid fuels are used in appliances which are fitted with flues.It should be emphasised that barbecue grills using charcoal, emit very high amounts ofcarbon monoxide and should only be used outdoors.4.4 Uncontrolled burningCarbon monoxide is a major gaseous product from fires resulting from uncontrolled burningof carbonaceous material. Varying concentrations of carbon monoxide are produced,depending on the material, burning conditions, etc.4.5 Tobacco smokingSmoking produces a significant concentration of carbon monoxide.4.6 Internal combustion enginesA major source of carbon monoxide in the non-industrial environment is the combustionengine. The concentration of carbon monoxide in exhaust gas is normally in the range 1 % -3 % but may reach 7 % in a badly maintained or badly tuned engine.The exhaust gases from internal combustion engines (vehicles or electricity generators forexample) running in an enclosed space will quickly produce dangerous levels of carbonmonoxide.4.7 Multi-occupancy and multi-storey buildingsIn multi-occupancy and multi-storey buildings, carbon monoxide produced in one area maybe transported to and leak into another part of the building, e.g. across roof spaces,between floors, along ducting and in shared flues.SIST EN 50292:2002
