Hamad Medical Corporation (HMC) is seeing a sharp rise in carbon monoxide poisoning cases recently, prompting the healthcare facilitator to issue warnings to the public.
The colourless and odourless gas, is highly toxic and can be fatal, if inhaled, even in low concentration, according to experts. HMC has issued a warning to the public about the danger of carbon monoxide poisoning resulting from burning wood or charcoal indoors or in an enclosed space.
Burning wood or charcoal indoors without proper ventilation causes the gas to build up, leaving occupants vulnerable to suffocation and other severe complications including permanent brain injury or death.
Hamad General Hospital’s (HGH) Emergency Department has witnessed a sharp rise in the number of admissions caused by carbon monoxide poisoning. This has been due to residents burning wood or charcoal in confined spaces while trying to keep warm during the recent cold weather.
"Symptoms of carbon monoxide poisoning can start to appear within 5 to 20 minutes of exposure. However, lower concentrations may lead to a delay in the onset of symptoms and chronic exposure may cause symptoms to appear over days, weeks or months," said Dr Dominic Jenkins, Senior Consultant in Emergency Medicine and Deputy Chair for Clinical Affairs at HMC.
As the charcoal burns, the amount of carbon monoxide in the room gradually increases — without the occupants of the room being able to detect it. As it is inhaled, carbon monoxide attaches to the haemoglobin in the blood preventing it from being able to carry oxygen.
"Mild carbon monoxide poisoning may feel like food poisoning or the flu, although unlike the flu, carbon monoxide poisoning does not cause a high temperature (fever). Symptoms can include headache, tiredness, dizziness, nausea or vomiting. More severe cases of poisoning may cause muscle cramps and fainting and loss of consciousness due to the poor delivery of oxygen to the heart and the brain. The effects of carbon monoxide poisoning are particularly dangerous for children, pregnant women, people with chronic heart diseases, respiratory problems or anaemia," he added.
If case carbon monoxide poisoning is suspected, occupants should immediately leave the building, call 999 or seek medical assistance.
