Sodium permanganate is an inorganic compound with the chemical formula of NaMnOfour。Soluble in water, ethanol and ether.It has strong oxidizability, and its reduction products vary with the acidity and alkalinity of the medium: it is reduced to Mn in acid solution2+；It is reduced to MnO in slightly acidic, neutral and slightly alkaline solutiontwo；It is reduced to Na in strong alkaline solutiontwoMnOfour, further compare with Mn2+And produce intermediate valence compound MnOtwo, as a characteristic reaction of manganese compounds.[5]Sodium permanganate is easy to explode when it contacts with concentrated sulfuric acid, and will burn when it contacts, rubs or collides with organic matter, and will emit oxygen when heated.It can be used as oxidant, bactericide, antidote, and substitute for potassium permanganate.
Listed in the List of Explosive Hazardous Chemicals[3]，It shall be controlled in accordance with the Public Security Management Measures for Explosive Hazardous Chemicals[4]。
Health hazard: This product is strongly irritating.High concentration exposure seriously damages mucous membrane, upper respiratory tract, eyes and skin.Contact may cause burning, cough, wheezing, shortness of breath, laryngitis, headache, nausea and vomiting.
Environmental hazards
Hazardous characteristics: strong oxidant.It can explode when encountering sulfuric acid, ammonium salt or hydrogen peroxide.It can cause spontaneous combustion when encountering glycerol and ethanol.There is a risk of combustion and explosion when contacting or mixing with reducing agents, organics, combustibles such as sulfur, phosphorus, etc.
Isolate the leakage contaminated area and restrict access.It is recommended that emergency personnel wear self-contained breathing apparatus and anti poison clothing.Do not touch the leakage directly.Do not allow the leakage to contact with organics, reducing agents and inflammables.Small amount of leakage: mixed with sand, dry lime or soda ash.Collect them in closed containers and mark them for disposal.Large amount of leakage: cover with plastic cloth and canvas to reduce flying.Then collect and recycle or transport to waste disposal site for disposal.[1]
Protective measures
Respiratory system protection: It is recommended to wear a hood type electric air supply filter type dust respirator when it may be exposed to dust.
Eye protection: protection has been made in respiratory system protection.
Body protection: wear adhesive tape anti-virus clothing.
Hand protection: wear neoprene gloves.
Others: Smoking, eating and drinking are prohibited at the work site.After work, take a shower and change clothes.Keep good hygiene habits.[1]
First aid measures
Skin contact: Take off the contaminated clothes immediately and wash with plenty of flowing water for at least 15 minutes.Get medical attention.
Eye contact: immediately lift the eyelid, and thoroughly flush it with a large amount of flowing water or physiological saline for at least 15 minutes.Get medical attention.
Inhalation: quickly leave the site to a place with fresh air.Keep the respiratory tract unobstructed.If breathing is difficult, give oxygen.If breathing stops, perform artificial respiration immediately.Get medical attention.
Ingestion: Rinse the mouth with water and drink milk or egg white for those who take it by mistake.Get medical attention.
Extinguishing method: extinguishing agent: fog water, sand.[1]
Storage and transportation
