Chemical: Sulfuric acid, manganese(2+) salt (1:1), monohydrate

Regulation (EC) No 1831/2003 (amended)

Sulfuric acid, manganese(2+) salt (1:1) monohydrate is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Sulfuric acid, manganese(2+) salt (1:1) monohydrate are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)

Manganese (II) sulphate, monohydrate: Does not have an individual approval but may be used under an appropriate group standard

Flash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)

Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

SYMPTOMS: Symptoms of exposure to this compound include mild irritation of the eyes and mucous membranes of the respiratory tract. Symptoms of exposure to this type of compound include apathy, anorexia, headache, recurring leg cramps, loss of balance, clumsiness, pneumonia and associated pulmonary problems. Other symptoms include central nervous system damage, pulmonary system damage, upper respiratory infections, languor, sleepiness, weakness in the legs, a stolid, mask-like face, muscular twitchings, varying from a fine tremor of the hands to coarse, rhythmical movements of the arms, legs and trunk; slight increase in tendon reflexes, ankle and patellar clonus, typical Parkinsonian slapping gait and minute handwriting (affected by micrographia). It can cause spastic gait, insomnia, dystonia, fatiguability, asthenia and an inability to concentrate. It can also cause impaired mentation, ataxia, difficulty in walking and decreased movement of the eyelids and eyes. Other symptoms include lethargy, edema, extrapyramidal effects, sleep disturbances, dermatitis, irritability, liver enlargement, increased muscle tone, muscular cramps, mental deterioration, excessive salivation and perspiration, sexual disturbances, blood changes and, very rarely, hypothyroidism. Exposure can cause spasms, arthralgias and speech disturbances such as slurred speech, slow and monotonous voice tone, inability to speak above a whisper, difficult articulation and incoherence, and even complete muteness. Psychosis may occur with unaccountable laughter, euphoria, impulsive acts, absentmindedness, mental confusion, aggressiveness and hallucinations. Propulsion, retropropulsion and lateropropulsion are affected with no movement for protection when falling. Absolute detachment may occur, broken by sporadic or spasmodic laughter. Inhalation may cause acute bronchitis, nasopharyngitis and itching. Numbness of the extremities and impairment of libido may occur. Other effects include weakness, delusions；ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits toxic fumes of sulfur oxides. (NTP, 1992)

No evidence of carcinogenicity in rats and equivocal evidence in mice in 2-year feeding studies; [NTP] Intermittent inhalation studies of rats produced changes in testicular weight (0.5 mg/m3 for 45 days) and degenerative changes to brain (0.01 mg/m3 for 13 weeks); [RTECS] May cause irritation; Targets lungs and nerves; [Aldrich MSDS] See Manganese and linked occupational diseases.

Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. A water spray may also be used. (NTP, 1992)

In case of fire in the surroundings, use appropriate extinguishing media.

Fresh air, rest.

Rinse with plenty of water for several minutes (remove contact lenses if easily possible).

Rinse mouth. Seek medical attention if you feel unwell.

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.；SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.；INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.；INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)

SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.；STORAGE PRECAUTIONS: You should store this chemical under ambient temperatures, and protect it from moisture. If possible, it would be prudent to store this compound under inert atmosphere. (NTP, 1992)

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Store and dispose of according to local regulations.

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:；IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.；SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.；FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)
