Thoroughly clean and dry contaminated clothing and shoes before reuse.

Eye Contact: Flush eyes with plenty of water for at least 15 minutes. Get immediate 

medical attention. 

Ingestion: Do not induce vomiting. If vomiting occurs, lean patient forward or place on 

left side (head-down position, if possible) to maintain an open airway and 

prevent aspiration. Keep patient quiet and maintain normal body 

temperature. Get medical attention.

5.3 Special Protective Equipment and Precautions

Protect container from physical damage. Move container from fire area if it can be done without risk. Cool containers 

with water spray until well after the fire is out. Do not allow water to enter the containers. Stay away from the ends of 

tanks. For fires in cargo or storage area: Cool containers with water from unmanned hose holder or monitor nozzles 

until well after fire is out. If this is impossible then take the following precautions: Keep unnecessary people away, 

isolate hazard area and deny entry. Let the fire bum. Use extinguishing agents appropriate for surrounding fire. Avoid 

inhalation of material or combustion by-products.

See Section 4.2 for symptoms related to the physical, chemical, and toxicological characteristics.

11.3 Short and Long Term Effects

Inhalation 

Acute Exposure (Manganese): Dust or fumes may be irritating to the mucous membranes. Occupational 

exposure to dust or fumes has been reported to cause upper respiratory tract 

problems, black mucous membrane discharge from the nose, and 

neurological damage. Metal fume fever, an influenza-like illness, may occur 

Section 11: Toxicological Information
Ferromanganese, High Carbon Safety Data Sheet

Format: GHS Revised: April 24, 2015

Language: English (US) Version 2

Page 8 of 12

due to the inhalation of freshly formed metal oxide particles sized below 1.5 

microns and usually between 0.02-0.05 microns. Symptoms may be delayed 

4-12 hours and begin with a sudden onset of thirst, and a sweet, metallic or 

foul taste in the mouth. Other symptoms may include upper respiratory tract 

irritation accompanied by coughing and a dryness of the mucous 

membranes, lassitude and a generalized feeling of malaise. Fever, chills, 

muscular pain, mild to severe headache, nausea, occasional vomiting, 

exaggerated mental activity, profuse sweating, excessive urination, diarrhea 

and prostration may also occur. Tolerance to fumes develops rapidly, but is 

quickly lost. All symptoms usually subside within 24-36 hours.

Acute Exposure (Carbon): Inhalation of dust may cause slight mucous membrane irritation.

Chronic Exposure (Manganese): If sufficient quantities of manganese dust or fumes are inhaled and absorbed, 

systemic poisoning known as "manganism", a Parkinsonian-like syndrome 

may occur. It is characterized initially by anorexia, asthenia, headache, 

insomnia or somnolence, irritability, restlessness, and spasm or pain in the 

muscles. Manganese psychosis may follow with uncontrollable behavior, 

unaccountable laughing or crying, visual hallucinations, confusion and 

euphoria. Sexual excitement followed by impotence may occur. These 

symptoms may disappear with the onset of true neurological manifestations 

of slow, slurred and irregular speech, monotonous tone, double vision, 

impaired hearing, and difficulty with fine motor movements, and disturbances 

in gait and balance with frequent propulsion or retropulsion. Mask-like face, 

decreased movement of the eyelids and eyes and tremors of the upper 

extremities and head may also occur. Other signs and symptoms may 

include urinary bladder disturbances, excessive salivation and sweating, 

hematological changes, vasomotor disorders, decreased pulmonary function, 

kidney and possibly liver damage. Removal from exposure shortly after onset 

of symptoms usually results in improvement, although there may be residual 

disturbances in gait and speech. Once manganism is well established it 

becomes irreversible and progressive, but not fatal. An increased incidence 

of bronchitis and pneumonitis has been reported in studies of workers 

exposed to manganese dust and fume, and although these effects have 

been confirmed by animal experiments, they may represent an aggravation 

of a pre- existing condition. Allergic diseases of the respiratory tract have 

also been reported in one study.

Chronic Exposure (Carbon): Repeated or prolonged exposure may cause irritation and pulmonary 

disorders. Lung damage may result if sufficient exposure occurs.

Skin Contact

Acute Exposure (Manganese): 500 mg applied to the skin of rabbits caused mild irritation.

Acute Exposure (Carbon): Contact may cause irritation.

Chronic Exposure (Manganese): Sensitization has been reported in guinea pigs.

Chronic Exposure (Carbon): Repeated or prolonged contact may cause mechanical irritation.

Eye Contact

Acute Exposure (Manganese): Dust or fumes may be irritating to the eyes. 500 mg applied to the eyes of 

rabbits caused mild irritation.

Acute Exposure (Carbon): Contact with dust may cause mechanical irritation. May also cause 

conjunctivitis.

Chronic Exposure (Manganese): Fumes may cause conjunctivitis.

Chronic Exposure (Carbon): Repeated or prolonged exposure may cause mechanical irritation.

Ingestion

Acute Exposure (Manganese): Extremely large doses may cause gastrointestinal irritation and possibly 

systemic toxicity.

Acute Exposure (Carbon): Extremely large doses may produce gastrointestinal disturbances.

Chronic Exposure (Manganese): Manganese poisoning has been reported in persons drinking manganesecontaminated well water. Prolonged ingestion of manganese in water has 

produced lethargy, edema, and decreased movement of the eyes and 

eyelids.

Chronic Exposure (Carbon): No data available.
