Zinc oxide powder is a white powder-like substance, odorless and directly accessible to hands and skin. Zinc oxide reacts with hydrochloric acid in gastric juice to produce soluble zinc chloride, which can be absorbed by human body, but zinc ion is a trace element required by human body, and excessive inhalation can cause poisoning symptoms. Let's take a look at the effects and hazards of zinc oxide powder and protective measures.

Zinc oxide powder is a commonly used ointment in dermatology, and you must be wondering if prolonged exposure to zinc oxide powder is harmful to your body. Long-term exposure to zinc oxide, if properly protected by wearing a dust mask and protective clothing,, will not cause harm.

Symptoms of zinc casting fever caused by inhalation of zinc oxide powder include metallic taste in the mouth, thirst, dry throat, loss of appetite, chest tightness, dry cough, dizziness, pain in the extremities, high fever and aversion to cold.

However, in the production process of factory workers, zinc oxide powder is not very fine and large amount of zinc oxide dust can block sebaceous glands. Therefore, protective measures must be taken:Workers are advised to wear dust masks and protective clothing, and smoking and eating are strictly prohibited at the work site. In addition, zinc smelting industry, brass preparation and galvanizing work may produce zinc oxide fumes. To prevent haze, galvanized sheets cannot be directly welded and need to have the zinc film removed from the surface first.

Zinc oxide powder is a chemical and also has certain hazardous behavior characteristics. It reacts violently with magnesium and linseed oil by change. The mixture with chlorinated rubber may be subjected to high heat by heating to 215℃ or more problems, and a large amount of toxic fumes will be released. The following are the main hazards of zinc oxide powder.

The main ways of intrusion: inhalation, ingestion. Inhalation of zinc oxide soot can cause zinc casting fever. The symptoms include metallic taste in the mouth, thirst, dry throat, loss of appetite, chest tightness, dry cough, dizziness, pain in the extremities, and high fever. Large amounts of zinc oxide dust can block sebaceous ducts. Acute toxicity, low toxicity, ld50 of 7950 mg/kg. It reacts violently with magnesium and linseed oil, and when heated above 215°C, mixtures containing chlorinated rubber may explode. It decomposes at high temperature and emits toxic fumes. Combustion (products, naturally proceeding reaction products are unknown.

Therefore, there are certain protective measures for exposure to zinc oxide powder, specific protective measures are as follows:

1, respiratory protection, it is recommended that workers wear a dust mask.

2, eye protection, if necessary, you can use a mask.

3, protective clothing, wear tight-sleeved work clothes and long rubber shoes.

4. Smoking, eating and drinking are strictly prohibited in other workplaces. Shower and change clothes after work. Pay attention to personal hygiene.
