Manganese carbonate is an important chemical raw material, widely used in metallurgy, ceramics, glass, fertilizer and other fields. However, manganese carbonate has a certain degree of danger, so strict compliance with regulations is required during storage and transportation to ensure safety. This article will detail the safe storage and transportation specifications of manganese carbonate. Hazard of
1. manganese carbonate
manganese carbonate is pink to almost white crystalline or amorphous powder, odorless. Relative density 3.1. The decomposition temperature is about 500°C. Stable in dry air, it quickly oxidizes to a brown compound when wet, and decomposes into manganese oxide and carbon dioxide gas when heated. Soluble in dilute acid, insoluble in water.
manganese carbonate dust is irritating to eyes and skin. Inhalation of manganese carbonate dust can cause respiratory irritation, long-term exposure can cause chronic rhinitis, bronchitis and other respiratory diseases. Misuse of manganese carbonate can cause oral, throat and digestive tract irritation symptoms, severe cases can occur collapse, coma. Long-term exposure to manganese carbonate dust can cause neurological dysfunction.
2. manganese carbonate storage specification
1. storage place should be dry, well ventilated, avoid direct sunlight.
2. Storage containers shall be well sealed to prevent leakage.
3. The storage area should be kept away from fire and heat sources, and smoking and open flames are prohibited.
4. should be stored separately with oxidants, acids, food, do not mix storage.
5. The storage area shall be provided with suitable materials to contain spills.
3. of manganese carbonate transportation specifications
1. Before transportation, check whether the packaging container is complete and sealed. During transportation, ensure that the container does not leak, collapse, fall, or damage.
2. It is strictly prohibited to mix with oxidants, acids, food, etc.
3. During transportation, it shall be protected from sun exposure, rain and high temperature.
4. The vehicle shall be thoroughly cleaned after transportation.
4. manganese carbonate leakage treatment
isolate the leakage pollution area and restrict access. It is recommended that emergency personnel wear dust mask (full face mask) and protective clothing. Collect with a clean shovel in a dry, clean, covered container. If there is a large amount of leakage, collect and recycle or transport to waste treatment site for disposal.
5. first aid measures
skin contact: remove contaminated clothing and rinse with running water.
Eye contact: Lift the eyelid, flush with flowing water or normal saline, and seek medical attention in time.
inhalation: quickly leave the scene to fresh air, keep the respiratory tract unobstructed. If it is difficult to breathe, give oxygen and seek medical attention in time.
Intake: Drink plenty of warm water to induce vomiting. Gastric lavage, drainage, and timely medical treatment.
6. protective measures
engineering control: strictly airtight, provide sufficient local exhaust. Mechanized and automated as much as possible. Safety shower and eyewash equipment provided.
Respiratory system protection: when the dust concentration in the air exceeds the standard, you must wear a self-priming filter dust mask. Emergency rescue or evacuation, should wear air respirator.
eye protection: wear chemical safety goggles.
body protection: wear anti-poison penetration overalls.
hand protection: wear rubber gloves.
Other protection: Smoking, eating and drinking are prohibited at the work site. After work, shower and change clothes. Maintain good hygiene habits.
To sum up, manganese carbonate has important application value in the field of chemical production raw materials, but its risk can not be ignored. Therefore, in the process of storage and transportation, we must strictly abide by the norms to ensure safety. At the same time, scientific and reasonable measures should be taken to ensure the safety of personnel and the environment in case of leakage and first aid.
