1. Intoxication during pregnancy entails high risks for the mother as it increases the risk of short term complications The foetus risks death abnormal development and brain damage due to lack of oxygen Carbon monoxide intoxications are frequent and their consequences are very serious They can cause immediate death but may also entail complications and after effects which are often left untreated It is therefore essential to avoid them by installing alarm and safety systems inside the home The content of this document can be changed without previous notice MEASUREMENTS AND NORMS The result of the analysis is given in volume units called ppm Pom means part per million When the COACH alarm indicates a result of 60 ppm as a measurement of maximum level of expo sure this means that there has been a proportion of 60 volumes of CO 60 cm3 for 1000 000 volu mes 1m3 of air or 60 millionths of CO in the air Starting from this level of concentration the calculator takes into account exposure under a given amount of time in order to calculate the theoretical level of COHb If this level exceeds the threshold stipulated by the norm this alarm is triggered off The corresponding European norm EN50291 imposes the theoretical COHb limit by giving the follo wing standard levels of exposure Level of exposure No alarm before Alarm before 30ppm 120 minutes 50ppm 60 minutes 90 minutes 100ppm 10 minutes 40minutes 300ppm 3 min2. the premises leaving the doors and windows open In a multi storey building make sure that other occupants have been warned of a risk of CO intoxication 3 Do not return to the premises as long as the alarm is activated red LED if the alarm has been acknowledged 4 Call a doctor immediately if any symptoms associated with CO appear headache nausea vomi ting and indicate that there is suspected CO intoxication see the symptoms described in the chapter measurements and norms 5 If the alarm is triggered off the relay automatically cuts off the heater or boiler When the alarm stops the relay is reactivated and the appliance can be started up again If you are present and The content of this document can be changed without previous notice if the appliance has to be restarted manually first you must make sure that the source of CO has been identified and that the fault has been corrected Call the maintenance service for your heater or boiler and inform them about the incident Do not switch on the appliance which has produced the CO which triggered off the alarm before it has been checked by a professional The following points may modify the measures recommended above and might have to be taken into account when your boiler or heater is installed A It may be the case that excessive ventilation increases the level of CO in the premises when for example traffic is particularly heavy outside especially when it is cold In this
