Hazards and Protection.
Storage
Store in a tightly closed container in a cool, dry place, away from heat and direct sunlight.
Handling
Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data sheet must be observed.
Protection
Wear appropriate protective eyeglasses or chemical safety goggles, gloves and adequate protective clothing to minimise skin exposure. Wash hands and face thoroughly after handling and before eating, drinking smoking or using toilet facilities.
Respirators
In dusty conditions, wear a dust mask or air-supplied breathing apparatus depending on levels of dust.
Small spills/leaks
Clean up personnel should wear protective clothing including breathing apparatus in dusty conditions. Avoid generating dust. Vacuum or sweep up material and place in suitable containers. Hold for reuse or disposal. Wash spill site with soapy water after initial pickup is complete.
Stability
Stable under normal conditions of use.
Incompatibilities
Can react with strong acids, strong oxidising agents and powdered metals. May react violently with hydrogen peroxide.
Decomposition
Carbon dioxide, sulphur oxides (SOx), including sulphur oxide and sulphur dioxide, oxides of manganese.

Fire.
Fire fighting
Extinguish fire using No data Wear a self-contained breathing apparatus with a full facepiece operated in the positive pressure demand mode with appropriate turn-out gear and chemical resistant personal protective equipment.
Fire potential
Material is non-flammable.
Hazards
Fire-fighters should wear full protective clothing including self-contained breathing apparatus. Use water spray, dry chemical, carbon dioxide or chemical foam type extinguishers. Use equipment/media appropriate to surrounding fire conditions.

Exposure effects
Chronic inhalation or ingestion may result in nonspecific neurological symptoms of headache, apathy, and weakness of legs, followed by psychosis, and finally appearing with neurological symptoms similar to those of Parkinson's disease. In its acute form, manganese poisoning has an effect characteristic of other heavy metals, leading to metal fume fever if dust or fume is inhaled in sufficient quantity.
   Ingestion
May cause gastrointestinal irritation with nausea, vomiting and diarrhea.
   Inhalation
May cause respiratory tract irritation.
   Skin
May cause skin irritation. Low hazard for usual industrial handling.
   Eyes
May cause mild eye irritation.

First aid
 
   Ingestion
If victim is conscious and alert give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Seek medical attention.
   Inhalation
Remove from exposure to fresh air immediaetly - avoid becoming casualty. If not breathing, give artificial respiration. If breahting is difficult, give oxygen. Seek medical attention immediately.
   Skin
Flsu skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Seek medical attention if irritation develops or persists.
   Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids. Seek medical attention.
