2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. Eye
May cause mild eye irritation. Skin
May cause skin irritation. Low hazard for usual industrial handling. Inhaled
May cause respiratory tract irritation. 2.2 Health Effects - Chronic
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. An airborne concentration thought to be immediately dangerous to life or health is in the order of 10,000 mg/m3 (as Manganese).
2.3 First Aid
Swallowed
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.
Eye
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids. Seek medical attention.
Skin
Flush 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.
Inhaled
Remove from exposure to fresh air immediately - avoid becoming casualty. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Seek medical attention immediately.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
Treat symptomatically based on judgement of doctor and individual reactions of patient.
2.6 Toxicity Data
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
Long-term exposure at or below 0.5 to 1 mg/m3 should afford protection for those individuals who may be susceptible to the neurological effects of prolonged exposure to manganese. Accordingly, the Exposure Standards Working Group recommends an eight-hour TWA exposure standard of 1 mg/m3 for manganese and inorganic compounds. Although there is acknowledgement that the particle size distribution, type of manganese compound & oxidation state may play an important role in the development of both the neurological and respiratory effects of manganese, there is insufficient evidence to distinguish confidently between manganese fume, dust and other inorganic manganese compounds. For this reason it is recommended that a single exposure standard be applied for all inorganic manganese compounds, measured as inspirable dust (as Mn). Provided that the 8-hour TWA exposure standard is not exceeded, short-term exposures should not exceed 3 times the TWA exposure standard for more than a total of 30 minutes per 8-hour working day; and under no circumstances should the short-term value exceed 5 times the exposure standard (the general excursion limit approach).
3.2 Engineering Controls
Provide adequate general or local exhaust ventilation to keep airborne concentrations below the permissable exposure limits.
3.3 Personal Protection
Eye protection - chemical goggles. Skin protection - impervious gloves. Respiratory protection - L-type dust mask. Minimise dust-producing operations. Wash hands and face thoroughly after handling and before eating, drinking smoking or using toilet facilities.
3.4 Flammability
Material is non-flammable. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Store in a tightly closed container in a cool, dry place, away from heat and direct sunlight. No special transport requirements necessary.
4.2 Packaging / Labelling UN No. N/A Class None Allocated Sub Risk None Allocated Hazchem Code N/A Pack Group 0 EPG No. N/A Shipping Name MANGANESE SULPHATE, MONOHYDRATE Hazard HARMFUL
Risk Phrases R48/20/22 Harmful : danger of serious damage to health by prolonged exposure through inhalation and if swallowed.
Safety Phrases S2 Keep out of the reach of children. S22 Do not breathe dust.
4.3 Spills and Disposal
Spills
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.
Disposal
Dispose of in accordance with all Local, State and Federal regulations at an approved waste disposal facility.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Material will not burn or explode. Stable under normal conditions of use. Manganese sulphate can react with strong acids, strong oxidising agents and powdered metals. May react violently with hydrogen peroxide. Hazardous decomposition products include carbon dioxide, sulphur oxides (SOx), including sulphur oxide and sulphur dioxide, oxides of manganese. Hazardous polymerisation has not been reported. Commercial grade material is corrosive to most metals.
Extinguishing Media
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. 5 OTHER INFORMATION
