Coal smoke poisoning can be deadly

Each year, Bach Mai Hospital's Poison Control Center (Hanoi) provides emergency treatment for 10 to 20 patients poisoning by inhaling coal gas. In addition to the deaths, many people cannot return to normal because of brain damage.

On March 18, at the seminar "Bringing clean and friendly honeycomb coal into use", Dr. Pham Due, Director of Bach Mai Hospital's Center for Toxic Protection (Hanoi), said that charred coal will produce To poison, if burned in a well-ventilated place, it will dilute the concentration of toxins. If burning in a closed room, burning coal will burn off oxygen, concentration of toxins, causing anemia and human poisoning.

The critical condition of the patient depends on the time of brain ischemic fast or long. "We design houses very dangerous, even the hotel is closed, no ventilation holes. Therefore, in order to avoid poisoning of coal gas, the most important thing is the kitchen must be open. If coal gas accumulates In the house, no poisoning at the level will be poisoned slowly, ' Dr. Du explained.

This expert also said that each year, Bach Mai Hospital's Center for Poisoning Center provides 10 to 20 patients poisoning by inhaling coal gas. In addition to the deaths, there are also many people who cannot return to normal because of brain damage, even some people still live plants.

According to some recent surveys, in Hanoi city, 70% of households use gas, electricity and the rest use honeycomb charcoal for cooking. In the suburbs and other provinces, the rate is 30% using gas, electricity and 70% using charcoal.

For a long time, honeycomb coal is produced from raw coal dust mixed with mud and then pressed into members, not yet treated toxic. When burning coal toxic gases such as SO ₂ , CO, CO ₂ , NO ₂ are very much released. When burning, sulfur in activated coal with O ₂ produces SO ₂ gas, people who inhale will have sore throat, pneumonia. The CO gas produced during the process of coal or incubation will be toxic to the nervous system.

After 13 years of research, Mr. Hoang Van Thuong (Hanoi) has released clean coal without using additives as chemicals and mud, but using plants to detoxify coal, so the amount of toxic substances discharged Very low environment.

Anh Thuong said, although the price of this type of coal is quite high (VND 2,900 / member, while the price of ordinary honeycomb is VND 1,700 / member), but with the advantage of using only 1/4 newspaper, it can burn burning, not burning with electricity like ordinary coal, emitting less harmful gas so people can still accept.

Hoang Thuong clean coal has been tested by the Technical Center 1 (General Department of Standards, Metrology and Quality - Ministry of Science and Technology) for toxic substances and dust all many times. Specifically, SO ₂ reduced 98%, NO ₂ reduced 59%, CO reduced 54% compared to the standard.
