Gas is usually easy to come into contact with, some of them are poisonous gas.
In the process of production, use, storage and transportation if you can't be effective protection, may cause harm to human body, cause serious accident.
The following is a list of common characteristics and hazard of toxic gas in the industrial gases, in order to increase our safety consciousness, to prevent the harm to human body and poisoning accidents.
1.Irritant gas, toxic gas chemical industry is often encountered.
The most common form of chlorine, ammonia, nitrogen oxides, phosgene, hydrogen fluoride, sulfur dioxide, sulfur trioxide and dimethyl sulfate, etc.
Can irritate the eyes and respiratory tract mucosa of excitant gas species
2. Toxic gas asphyxiation - can result from a lack of oxygen to the body.
Asphyxiation asphyxiation and can be divided into pure asphyxiation, blood cell asphyxiation.
Such as nitrogen, methane, ethane, ethylene, carbon monoxide, nitrobenzene steam, hydrogen cyanide, hydrogen sulfide, etc.
