Manganese powder is a flammable and explosive substance. In the production and preservation, people must pay attention to fire and explosion. The greater combustion heat of dust is, the smaller the particle will be.

Then the oxidation rate increases and it become easier to burn. Dust explosion requires three conditions: dust concentration,Safety and sanitation in production of electrolytic manganese powder Articles combustion substances and temperatures. Dusts of different substances have different explosive concentration. The concentration of manganese powder explosion is 210g/m3. The combustion substances refer to the concentration of oxygen. The temperature involves in lowest temperature that flame or spark burst the dust. So preventing burning occurrences should take the above three aspects into account.

Burning three conditions, that is a combustible material, oxidizing substances and sources of ignition. Fire, to stop the burning, that is to eliminate the burning conditions. Fire fighting in general there are three ways: the suffocation method is to remove the combustion material and a source of ignition; isolation, limit and stop the combustible material into the combustion zone; cooling method is to reduce the combustion temperature, to lower the temperature below the ignition point of combustible material . Manganese powder ignition point of 450 ° C, extinguish the burning manganese powder is suitable to use suffocation method and the isolation method.

Fire-fighting operation was gently cover the first use of asbestos in the fire source, and then dry powder fire extinguishing material scattered in the asbestos was on, until the flame goes out. In order to prevent the fire from spreading and to avoid the mixture of gas and dust explosion, fire fighting, and not to cause dust flying, and not to break the windows to avoid the formation. The product equipped with a container should be immediately transferred to safe areas. Body on fire, can not run around to quickly take off their clothes or asbestos was woolen been extinguished. Equipment or indoor fire, to immediately stop the operation of equipment, turn off all valves and fire fighting.

Plant domestic demand flare up, you should first flare location and environment to thoroughly clean equipment flare, the first device blowing clean, local removable parts should be detached and sent to a place of safety flare up and can not demolition or difficult to demolition must be before and after the flare site, disconnect the equipment system or partition isolation. Flare prepares a good and adequate fire fighting tools and materials. It develops effective fire prevention measures.

Manganese is one of the human body essential trace elements. Manganese uptake by the human body is absorbed in the intestine, mainly in the muscles, internal organs and brain. Manganese is the composition of the human variety of enzymes, play an important role in cell metabolism, Mn deficiency caused by osteoporosis, bone deformities, cartilage damage, such as lesions, but excessive intake of the body on the body to cause harm, cause poisoning. The clinical manifestations of manganese poisoning: light neurasthenia disease and autonomic dysfunction may be drowsiness, insomnia, headache, fatigue, memory loss and other symptoms. Irritability in some patients, nausea, and salivation increased loss of libido, sweating, numbness or pain, legs weakness. Low weight by language, manners slow, indifferent feelings or impulses. It often accompanied by psychiatric symptoms.

Therefore, metal powder supplier must be prepared to do labor protection and sanitation works. The specific practices are: the place which produces manganese dust needs control measures. The manganese dust exposed jobs should use protective masks. In workplace, smoking and eating are limited. People who are suffering from e nervous organic diseases, obviously neurasthenia syndrome, psychiatric, endocrine diseases will not be hired for the positions. At the same time, the workers need regular physical examination.Source:http://www.mhcmp.com
