Physical and chemical properties of manganese sulfate

[Density]: 3.12

: CH ₂ MnO4

: 132.962

: 132.933365

[ PSA ]：72.42000

It should be stored in a cool, ventilated, and dry warehouse. It should be protected from moisture, heat, and deterioration. During transportation, it should be protected from rain and sun exposure. Handle with care during loading and unloading to prevent packaging damage. When a fire breaks out, water, sand, and fire extinguishers can be used to extinguish it.

[Stability]:

Stable in dry air, exposed to humid air, gradually turning brownish black due to oxidation. Decompose when heated. Hydrolysis occurs when boiling with water.

Hazard statement

Toxicological data

Health hazards: Harmful by inhalation, ingestion, or transdermal absorption, with irritant effects. Long term inhalation of dust from this product can cause chronic manganese poisoning, with early symptoms mainly including neurasthenia syndrome and neurological dysfunction, and later developing tremor paralysis syndrome.

Environmental hazards: Harmful to the environment and can cause pollution to water bodies.

Explosive hazard: This product is non flammable and has irritant properties.

Oral - Rat LD50：2150 mg/kg； Mouse LD50： 2330mg/kg。[1]

First aid measures

Skin contact: Remove contaminated clothing and rinse with running water.

Eye contact: Immediately lift the eyelids and rinse with plenty of flowing water or saline solution for at least 15 minutes. Seek medical attention.

Inhalation: Quickly leave the scene and move to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, administer oxygen. If breathing stops, immediately perform artificial respiration. Seek medical attention.

Ingestion: Rinse mouth with water and drink milk or egg whites. Seek medical attention.

fire prevention measures

Dangerous characteristic: Cannot burn on its own. Under high heat decomposition, toxic gases are released.

Harmful combustion products: sulfur dioxide.

Fire extinguishing method: Firefighters must wear full body fire and gas protective clothing and extinguish the fire in the upwind direction. When extinguishing a fire, try to move the container from the fire scene to an open area as much as possible. Then select appropriate fire extinguishing agents based on the cause of the fire to extinguish it.

Emergency response to leakage

Emergency response: Isolate the contaminated area and restrict access. It is recommended that emergency personnel wear dust masks and general work clothes. Do not come into direct contact with the leaked material.

Minor leakage: Avoid dust, carefully sweep up, collect and transport to waste disposal site for disposal.

Massive leakage: Collect and recycle or transport to waste disposal sites for disposal.

Handling and Storage

Precautions for operation: Closed operation, local exhaust. Prevent dust from being released into the workshop air. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety goggles, anti toxic work clothes, and rubber gloves. Avoid generating dust. Avoid contact with acids. Equip with emergency response equipment for leaks. Empty containers may contain residual harmful substances.

Storage precautions: Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. Protect from direct sunlight. Sealed packaging. It should be stored separately from acids and avoid mixing storage. The storage area should be equipped with suitable materials to contain leaked materials.Manganese sulfate pentahydrate
