Further to my post yesterday. I went to the walk in centre at the hospital yesterday afternoon and got seen within half an hour. I explained what had happened regarding the gas leak to the doctor who saw me. He put a pulse monitor on my finger and then checked my blood pressure. He looked on his computer and went on the internet and then told me I was fine as propane cannot emit carbon monoxide (wrong, wrong, wrong). Headache gone although I don’t think it will take much to bring it back. Still feeling bit queasy and dizzy. I have been feeling like this for many months, but obviously a lot worse when the two leaks happened. I went to the doctor weeks ago and had blood tests but obviously they didn’t test for carbon monoxide at the time as I hadn't been suspicious it was that, but now wondering if we have had low level of leakage from the boiler for a long time. We have been in the mobile for 16 months now and although I don't live there full time I stop there at weekends. They thought my symptoms at the time were to do with anxiety as I was shaky, heart racing, dizzy, headachey.

Our dog is having breathing problems at the moment and is under investigation by the vet at the moment (thought it was reverse sneezing she was suffering from) and my partner is feeling constantly tired all the time. We had the calor gas service engineer out last time and he fixed the fault and says it would be okay but we are obviously going to have another service engineer out now although we are now hooked up to a full canister of gas now which should prevent the problem.


The doctor at the walk in centre at A&E was totally incorrect in what he was saying that propane does not cause carbon monoxide poisoning, I found numerous internet sites including a fact sheet from Calor Gas stating that propane does cause Carbon Monoxide and you can smell it (as it had odorant added for safety) once the volume of leakage exceeds 5%. It is a very low lying gas but certain conditions (like leakage from boilers) and as in the case of the previous leak we had where the wind was pushing the gas upwards underneath the mobile through the bedroom floorboards. You are not allowed to completely block the sides of the mobile on floor level as if there is a leak it can accumulate and then explode which is why in certain weather conditions leaking gas can be pushed upwards. If propane mixes with water it creates harmless carbon dioxide. Mixed with oxygen it can cause carbon monoxide.

The carbon monoxide detector that my Mum bought us following the first leak did not go off on Saturday although I tested it afterwards by pressing the button and it worked okay. This is due to the fact that propane is a natural gas, and you need a different type of monitor for butane/propane although we didn’t know at the time. Now we know.

The doctor thinks I have a flu bug or something similiar as my Oxygen sats were 94 and if they are under 92 there is a problem and he said if they had been lower he would have sent me for a blood test. He also said that he wouldn't expect me to still be suffering from symptoms of posioning (even though it stays in your blood for a while). I think the doctor yesterday was hinting that my symptoms were psychosomatic.
 
Crikey - having just done a course on the safety of propane gas installations I would be more worried about my home exploding than carbon monoxide poisoning.

I think what the doctor may mean is that breathing propane wont cause carbon monoxide poisoning, its the incomplete combustion of propane that causes carbon monoxide formation.

Hope you feel better soon.
 
I know how you feel - I suffered this last summer in my Mum's caravan. I kept having headaches etc etc and said i could smell gas in my room, but we couldn't smell it in any other rooms in the caravan which we thought was strange.

Got the gas man out and we had a leak in one of the pipes underneath. The caravan in fenced in around the bottom so it trapped the gas in. The reason I could only smell it in my room was apparently because, as you say, that sort of gas is very heavy and will find the lowest point to collect in - there was a dip in the concrete base directly under my room. if it had gone undetected for longer it would have smelt through out the caravan.

I suffered effects on and off for about two weeks. the gas man said we were lucky as one spark and the whole lot would have gone up!

Hope you feel better soon.
 
Thank you for your help Porkie. I appreciate it as everyone seems to be thinking I am making a fuss. I hope I still don't feel like this in a fortnight though.
 
Any fuel containing carbon, eg Propane , natural gas. coal coke, wood can produce Carbon Monoxide by partial combustion . But Propane itself can nomore give you Carbon Monoxide poisoning than a fence post can.
 
The correct way to test for carbon monoxide poisoning is to test arterial blood. I know this because I had it done. I suspected I had mild carbon monoxide poisoning from a leaky car exhaust but no-one believed me. I could tell there was something wrong because I do athletics and I could hardly finish a session and otherwise had the symptoms you describe above. Carbon monoxide poisoning often mimics the symptoms of flu. It took about 3 months for me to feel back to normal though I was never really ill but it did trigger my asthma and I had to take a steriod inhaler for this time. I also got a lot of viral infections too.

There seems to be a great deal of ignorance about the dangers of carbon monoxide poisoning in the medical profession. Apparantly leaky car exhausts are a common cause but if you get a very small dose not very often most people won't notice it. Most carbon monoxide alarms are not sensitive enough. I got one for my car which measured as low as 1 ppm and I can tell you by trial and experience if it goes above 5 on a car journey you are in trouble yet most only measure above 10 or 20ppm!

Surely your caravan should have an annual landlord's gas safety certificate? If your landlord's gas safety installer isn't testing properly for carbon monoxide, contact CORGI.

I don't know what to suggest but having suffered from it once, I refused to drive that car again and bought a new car. (There were various attempts to fix it but none of them were entirely successful). I actually hired a car for a month while it was sitting in the drive because I didn't want to drive it!
 
Sure, that may be the correct way to test for CO poisoning - but you ONLY get CO poisoning as a result of incomplete combustion. OP says it was propane gas - the likelihood of her getting CO poisoning was somewhat less than that of her chewing on a piece of silver paper left on a sweet by mistake with a filling and igniting the leaking gas.
 
Carbon Monoxide will not come from the gas cylinder (not unless someone has set it alight).

Carbon Monoxide is the result of incomplete combustion so for instance if the boiler has not been maintained correctly the result of incomplete combustion will be Carbon Dioxide.

It is all the gas appliances such as the boiler, heater and cooker that need to be checked out to determine if they have been correctly maintained and also if the flues, chimneys and vent panells are operating correctly. It may well be that there are no open ventilation panells in the caravan which are starving the gas appliances of oxygen in the air.

Get the gas switched off and get a proper gas engineer to check out everyting.
 
If you do not have adequate ventilation when operating gas appliences fumes can draw back into the room. Make sure that plenty of fresh air can get in.Fumes cant leave up the chimney if air isnt drawn into the room to replace them.
