Dufuduo Chemical Co., Ltd. (hereinafter referred to as Dufuduo, stock code 002407) is headquartered in Zhongzhan District, Jiaozuo City. It is primarily engaged in the research, development, production, and sales of high-performance inorganic fluorides, lithium-ion battery materials, semiconductor lighting and photovoltaic materials, as well as nanometal materials. The company is committed to pursuing a path of corporate standardization based on the principles of \"technological patenting, patent standardization, and standard internationalization.\" At present, the company is leading or currently involved in the formulation and revision of more than 20 standards for inorganic fluorides such as cryolite and hydrofluoric acid; it is also responsible for formulating and revising various industry standards, and has developed standard samples for products including cryolite and aluminum fluoride. Is everyone familiar with this unit? I am in an interview for a position at the branch of this company, Baiyin Zhongtian Chemical. I would like to know some information about the development of this organization, as well as information regarding occupational hazards. Please. . . .
The overall efficiency of the company is quite good; as for occupational hazards, it depends on the specific position.

Fluorine is a non-metallic element; excessive accumulation in the body leads to fluorosis, whose main symptoms include yellowing or blackening of teeth, X-shaped or O-shaped legs, hunchback, or an inability to extend the arms. Mild cases result in dental fluorosis, while severe cases cause fluorosis of the bones, potentially leading to a complete loss of the ability to work and take care of oneself. Once fluorosis sets in, it remains a chronic condition for life; medications can only slow down the progression of the disease. Hydrogen fluoride gas and fluorine-containing dust are present in the workplace, and can enter the human body through the respiratory tract and esophagus. Inhaling high concentrations of hydrogen fluoride can cause acute poisoning, irritating the mucous membranes of the eyes and respiratory tract; in severe cases, bronchitis, pneumonia, or pulmonary edema may occur, and even reflexive asphyxiation can happen. 50% of the fluoride that enters the human body gets deposited in the bones and teeth, and long-term exposure can cause damage to these bones and teeth. Hydrogen fluoride is extremely corrosive. Measures: Preventive measures against fluoride hazards and dust toxicity hazards. The decomposition of phosphate rock with sulfuric acid releases hydrogen fluoride gas, which then reacts with silicon dioxide in the phosphate rock to produce silicon tetrafluoride gas. Water is generally used to absorb the escaping silicon tetrafluoride, and the absorption equipment consists of an absorption chamber and an absorption tower. The maximum allowable concentration of hydrogen fluoride in the workshop is 1 mg/m3; when this concentration is exceeded, a self-priming filter respirator (full-face mask) or an air respirator must be worn. It is recommended to wear an oxygen or air respirator during emergency response or evacuation. Attention should also be paid to skin protection. Special masks should be worn in positions where fluorine-containing dust is generated. To prevent the accumulation of fluorine-containing gases or dusts, ventilation should be improved and the sealing of equipment enhanced. Workers exposed to dust should undergo regular health checks and have health surveillance records kept.
