Introduction
Burning coal briquettes may cause poisoning. It is safe when ventilation is adequate and combustion is complete, but poses risks in enclosed environments or when combustion is incomplete. If coal briquettes are burned in a well-ventilated area (such as outdoors or in a spacious room with open windows) and the combustion is sufficient—producing only small amounts of carbon dioxide without accumulation of toxic gases—normal use generally will not lead to poisoning, and there is no need for excessive concern.
Under normal circumstances, burning coal briquettes may cause poisoning. It is safe when ventilation is good and combustion is complete, but there are risks in enclosed environments or when combustion is incomplete. If in doubt, it is advisable to seek medical consultation in advance. The detailed analysis is as follows:
If coal briquettes are burned in a well-ventilated environment (such as outdoors or in a spacious room with open windows) and the combustion is sufficient, only small amounts of carbon dioxide are produced, without accumulation of toxic gases. Under such conditions, normal use generally does not lead to poisoning, so excessive concern is unnecessary.
However, if coal briquettes are burned in a closed or poorly ventilated environment (such as a bedroom with tightly closed doors and windows or a small confined room), incomplete combustion can generate large amounts of carbon monoxide. This gas cannot disperse and accumulates easily, leading to poisoning upon inhalation. Symptoms may include dizziness, nausea, and unconsciousness, and in severe cases, it can be life-threatening. Extreme caution is required in such situations.
When burning coal briquettes, ensure adequate ventilation at all times and avoid use in enclosed spaces. Use only qualified, high-quality coal briquettes to ensure complete combustion. If symptoms of suspected poisoning occur, immediately move to a well-ventilated area and seek prompt medical evaluation and treatment to prevent delays in care.
