SECTION 2: Hazards identification

Note: Health effects listed below are for exposure to metallurgical powders, dust, vapor or mist from altering the tool. No health effects have been reported for exposure to this material in solid form. In the form of a powder, this odorless, colorless, gray material may be flammable and may cause respiratory and/or skin irritation. Overexposure to this material in the form of metallurgical powder, dust, vapor or mist from grinding or sweeping is hazardous to health. Cobalt is an eye, skin and mucous membrane irritant and may cause temporary or permanent respiratory disease. Permanent respiratory disease can lead to disability or death. Preexisting pulmonary and skin conditions such as emphysema, asthma, bronchitis and dermatitis may be aggravated by exposure to this material. Inhalation Irritant/Sensitizer 10mg(Ni)/m3, 20mg(Co)/m3 or 10mg (Co)/m3 is immediately dangerous to life and health. Acute Overexposure: May cause respiratory tract irritation with wheezing, shortness of breath, and fits of coughing which may produce blood and soreness in the chest. May also cause weight loss, bronchitis, asthma, and inflammation of or damage to lung tissue. Chronic Overexposure: May cause build-up of dust in the lungs, allergic respiratory reaction, obstructed airways, and lung damage or disease, with symptoms as described in acute exposure. Previously exposed individuals may be at increased risk. Skin Contact Irritant/Sensitizer In the form of metallurgical powder, dust or mist from grinding Acute Overexposure: May cause irritation with inflammation, rash, and itching. May also cause allergic skin reaction if previously exposed. A rash may develop , usually in the flexor areas of the elbow, neck and face. Chronic Overexposure: May cause inflammation and/or rash (irritant or allergic contact dermatitis) Eye Contact: Irritant Acute Overexposure: May cause irritation with redness, pain, and itching. Chronic Overexposure: May cause conjunctivitis. Ingestion Irritant In the form of metallurgical powder, dust, or mist from grinding Acute Overexposure: May cause abnormally low blood pressure and gastrointestinal irritation with pain, vomiting, and sensations of hotness or nausea. Large doses may cause diarrhea. Severe exposure may cause heart damage, convulsions, or enlargement of the thyroid. Chronic Overexposure: May adversely affect the pancreas, thyroid gland, heart, or bone marrow.
