Do waste rock iron have any harm to human body?
Liquid sulfur, liquid sulfur is the main risk of low ignition point, easy to form toxic hydrogen sulfide, easy to burn violently, and contact with the skin will cause severe burns. The maximum allowable concentration of hydrogen sulphide in daily work is 10 * 10-6, according to the American Society of industrial hygienists. The highest concentration is 20 * 10-6, according to the occupational safety and health administration.
The pyrite pyrite smelting sulfur harm on environment and governance of the 1. indigenous smelting sulfur harmful, sulfur dioxide gas generated a strong stimulation, cause damage to the eyes and respiratory system, when the concentration reaches 8 * 10-6 to 20 * 10-6, causing coughing and eye discomfort, when the concentration exceeds 5 * 10-4, will endanger life. Damage to the environment is also very serious, in the indigenous smelting sulfur area, the surrounding farmland and forest were destroyed, barren, waste gas pollution serious destruction of the natural ecological balance.
What harm to the body without inhalation of pyrite, only in the machining process mainly has the following hazards: (a) sulfur has no toxicity to the environment and health hazards and governance of 1. solid sulfur solid sulfur itself, but when it enters the human body, can react with protein to generate hydrogen sulfide, in the intestine was partly absorbed, taking a large number of will hydrogen sulfide poisoning symptoms appear. Sulfur dust can also cause eye conjunctivitis, which can irritate the skin and respiratory tract. Sulfur is low in ignition, producing static electricity, flammable and explosive. To protect against the harmful effects of solid sulfur, people who are exposed to solid sulfur must wear protective clothing and protective glasses.
