Section 3: Hazards Identification Potential Acute Health Effects:

Very hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation. Slightly hazardous in case of skin contact (corrosive, sensitizer), of eye contact (corrosive). The amount of tissue damage depends on length of contact. Eye contact can result in corneal damage or blindness. Skin contact can produce inflammation and blistering. Inhalation of dust will produce irritation to gastro-intestinal or respiratory tract, characterized by burning, sneezing and coughing. Severe over-exposure can produce lung damage, choking, unconsciousness or death. Inflammation of the eye is characterized by

redness, watering, and itching. Skin inflammation is characterized by itching, scaling, reddening, or, occasionally, blistering.

Potential Chronic Health Effects:

Slightly hazardous in case of skin contact (sensitizer). CARCINOGENIC EFFECTS: Not available. MUTAGENIC EFFECTS: Mutagenic for mammalian somatic cells. Mutagenic for bacteria and/or yeast. TERATOGENIC EFFECTS: Not available. DEVELOPMENTAL TOXICITY: Not available. The substance may be toxic to blood, cardiovascular system, upper respiratory tract, skin, eyes. Repeated or prolonged exposure to the substance can produce target organs damage. Repeated exposure

of the eyes to a low level of dust can produce eye irritation. Repeated skin exposure can produce local skin destruction, or dermatitis. Repeated inhalation of dust can produce varying degree of respiratory irritation or lung damage. Repeated exposure to a highly toxic material may produce general deterioration of health by an accumulation in one or many human organs.

Section 4: First Aid Measures Eye Contact:

Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Cold water may be used. Get medical attention immediately.

Skin Contact:

In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Cover the irritated skin with an emollient. Cold water may be used.Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.

Serious Skin Contact:

Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate medical attention.

Inhalation:

If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.

Serious Inhalation:

Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation. WARNING: It may be hazardous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled material is toxic, infectious or corrosive. Seek immediate medical attention.

Ingestion:

If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Loosen tight clothing such as a collar, tie, belt or waistband. Get medical attention immediately.

Special Remarks on other Toxic Effects on Humans:

Acute Potential Health Effects: Skin: Depending on the duration of skin contact, it may cause reddening,  discomfort, severe irritation, and possible chemical burns. Chemical burns result in blistering of the skin  and possible scarring. Skin contact may cause allergic sensitization and reaction in susceptible individuals. Eyes: Contact with eyes will cause severe irritation, pain, reddening, watering, and possibly burns, corneal damage and blindness. Inhalation: It may be destructive to the tissues of the mucous membranes and upper respiratory tract. Symtoms may include respiratory tract irritation or burning sensation/burns of the mucous membranes, breathing difficulty, coughing, wheezing, shortness of breath, dyspnea (labored breathing), nasal congestion, laryngitis, sore throat, headache, nausea, vomiting, and Methemoglobinemia (a condition that affects the ability of the blood to carry oxygen), and cyanosis (blue color of the skin due to lack of oxygen). Inhalation of low levels can cause allergic sensitization and reaction in susceptible individuals. Severe inhalation over-exposure can be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure may be delayed. Ingestion: Harmful if swallowed. It can cause severe irritation and burns of the mouth, throat, esophagus, and other tissues of the digestive tract, nausea, vomiting, diarrhea. Conversion of hemoglobin to methemoglobin may also occur producing cyanosis (see acute inhalation). It may also cause a fall in blood pressure, ringing in the ears, shortness of breath, and affect behavior/central nervous system (headache, vertigo, convulsions). Ingestion of large volumes may cause coma and be fatal as a result of circulatory collapse. Chronic Potential Health Effects: Skin: Repeated or prolonged skin contact to low concentrations may cause dermatitis. Inhalation: Repeated or prolonged inhalation may cause allergic reaction in sensitized individuals. Inhalation/Ingestion: Prolonged or repeated exposure by inhalation or ingestion may affect metabolism (decreased appetite, weight loss), spleen, thyroid and blood/cause bone marrow damage(decreased leukocyte count, anemia). It may also cause liver, kidney, and bone marrow damage. This substance is a blood toxin. Prolonged
