Anthracite poisoning symptoms?

summary

Anthracite has high fixed carbon content, low volatile yield, high density, high hardness, high ignition point and no smoke during combustion. Black, hard and metallic. Friction with grease will not pollute, the fracture will be shell like, and the flame will be short and smoke will be less. No coking. Generally, the carbon content is more than 90%, and the volatile matter is less than 10%. There was no glial layer thickness. The calorific value is about 6000-6500 kcal / kg. Sometimes it is called semi anthracite if the content of volatile matter is extremely high; Very small is called high anthracite. Anthracite poisoning symptoms? Let's talk about it

Anthracite poisoning symptoms?

The time of poisoning is short, the carboxyhemoglobin in blood is 10% - 20%. The early symptoms of poisoning include headache, dizziness, palpitation, nausea, vomiting, weakness of limbs, and even transient fainting. Generally speaking, the patient is still conscious and inhales fresh air. After leaving the toxic environment, the symptoms disappear rapidly and no sequelae is left.

If the rescue is timely, the patient can wake up quickly and recover completely within a few days, generally without sequelae.

It is found that if the time is too late, too much gas is inhaled, or high concentration of carbon monoxide is inhaled in a short time, the concentration of carboxyhemoglobin in blood is often more than 50%. The patient presents with deep coma, disappearance of various reflexes, incontinence of urine and urine, cold limbs, decreased blood pressure, shortness of breath, and will soon die. In general, the longer the coma time, the more serious the prognosis, often leaving dementia, memory and understanding decline, limb paralysis and other sequelae.
