As temperatures drop in South Africa, the use of imbawulas (coal braziers) for heating and cooking has increased.However, emergency services are cautioning against indoor use due to carbon monoxide poisoning risks.Five young people died from suspected carbon monoxide inhalation after sleeping in a room with a burning coal braai stand.The gas, which is odourless and colourless, can cause unconsciousness or death in enclosed spaces.Health experts warn that burning wood or charcoal releases toxic emissions, fine dust particles, and pollutants that harm respiratory health.Precautions include using imbawulas outdoors, ensuring proper ventilation, avoiding treated wood or plastics, and extinguishing fires before leaving.Vulnerable groups like children, elderly individuals, and those with respiratory conditions are at higher risk.Emergency services urge residents to follow safety guidelines to prevent accidents and fatalities during winter.
