SAFETY
Today unfortunately we still hear about accidents, sometimes deadly, caused by carbon monoxide poisoning. In effect, the danger of gas installations in the domestic field is minimally due to the fuel gas flammability but mostly due to the formation of carbon monoxide (CO) and especially to its accidental release and stagnation in inhabited places.
Safety of a functional system and danger of an inefficient system

Today unfortunately we still hear about accidents, sometimes deadly, caused by carbon monoxide poisoning. In effect, the danger of gas installations in the domestic field is minimally due to the fuel gas flammability but mostly due to the formation of carbon monoxide (CO) and especially to its accidental release and stagnation in inhabited places. Carbon monoxide is an odorless gas, so it is undetectable and consequently deceitful precisely when it it is mixed to other gases, such as gases generated by combustion. Subjects that suffered of prolonged loss of consciousness after exposition to carbon monoxide can be subjected to permanent injuries: in most of the cases they suffer of nervous system injuries, that can also extend to the cardiovascular system and other organs. The most common consequence of carbon monoxide poisoning is oxygen deficiency.



Hartridge diagram shows that an adult faints and risks to go into a coma if exposed for one hour to a place containing 0.1% carbon monoxide. If the exposure in the same place persists for an additional hour, the subject will certainly pass away.

A 0.5% of carbon monoxide leads to death in 5/6 minutes. Apparently peacefully asleep, the intoxicated person manifests a healthy rosy complexion and bright red lips: none of the symptoms prefigures that the person is in real danger. On the contrary, to save the subject it is necessary to promptly intervene: the person must be brought outside the intoxicated place and it is necessary to call for medical help. In this case, it is important to remember that even the rescuer needs to prevent himself from the risk of intoxication by promptly aerating the carbon monoxide poisoned place, by breathing through a wet handkerchief and breathing fresh non poisoned air in order to protect the respiratory system.

The following chart shows the human general symptoms related to CO percentage in the blood

CO percentage in the blood Symptoms
 
0-10% Usually not felt or taken for a general discomfort
 
10-20% Headache, shortness of breath, chest pain
 
20-30% Pulsating migraine, nausea, vomit, fatigue, loss of concentration
 
30-40% Dizziness, fatigue, weakened mental processes
 
40-50% Rapid breathing, increased heart beat, dizziness, confusional state
 
50-60% Respiratory insufficiency, collapse, convulsions and coma
 
60-70% Respiratory insufficiency, low blood pressure and coma
 
More than 70% Coma, imminent death

From a chemical point of view, during the combustion reaction, the carbon monoxide formation takes place in the following way:


The carbon monoxide generates from incomplete combustion, that is in deficiency of oxygen.

There are two main causes: Vent flap absent or under-dimensioned (vent flap dimensioning has the aim to lead the correct amount of air for the combustion and must be properly installed).

Obstruction of the exhaust system caused by the products of combustion.

If the products of the combustion are not properly exhausted, whether because of an obstruction or because of an erroneous vent flap dimensioning, the comburent air can hardly flow. It is very important to have a flue system that works properly: in every condition (except for very short periods of transience) it is fundamental to avoid any fumes return phenomenon in the room (backup). To prevent from this phenomenon, as we already clarified, the characteristics of the system (vent flaps, appliance, chimney or chimney flue) must consent, in case of natural draught, the formation of a proper depression inside the flue pipe and of the chimney/chimney flue and, in case of artificial draught, a proper depression inside the chimney/chimney flue.

Therefore, it is substantial to work with extreme accuracy in all the interventions on the heating system, even when they seems ordinary. Independently from the nature of the intervention, the vent flap suitability and the flue system checks must always be done.
