Samarium Cobalt Alloy Powder (2:17) Co-reduced

SECTION 2: Hazards identification

2.1 Classification of the substance or mixture

R11, R42/43, R53 Based on the cobalt contained within the alloy, this mixture is classified as dangerous according to Directive 67/548/EEC.

Physical hazards

Material is flammable

2.3 Other hazards

May cause sensitisation by inhalation and skin contact Prolonged exposure may cause chronic effects

Environmental hazards

May cause long-term adverse effects in the aquatic environment Specific Hazards: Elevated temperatures or mechanical action may form dust or fumes which may be irritating to the eye, mucous membranes and respiratory tract. Heating above the melting point releases metallic oxides which may cause metal fume fever by inhalation. The symptoms are shivering, fever, malaise and muscular pain. Acute exposure to cobalt metal, dust and fume may cause irritation of skin and eyes. In sensitized individuals, exposure causes an asthma- like attack, with wheezing, bronchospasm and dyspnea. The effects may be delayed. Suspect cancer hazard. Mechanical processing may cause dust. High concentrations of dust may form explosive mixture with air. Main Symptoms: Irritation of nose and throat. Irritation of eyes and mucous membranes. Cough, shortness of breath. Wheezing. Sensitization. General Comments on the preparation: This material is thought to be of low acute toxicity. However, the long-term inhalation of Cobalt is reported as producing pulmonary fibrosis, no data is available for this alloy, but it is assumed that it will present a similar hazard. Cobalt is an allergen and, although no data is available for this alloy, it is assumed that it will present a similar hazard; the material is classified on the basis of the Cobalt content. The absorption of Cobalt or its compounds is reported as producing adverse side effects upon heart muscle. Changes in blood factors such as red blood cell count or haemoglobin content have also been reported. The other components are not thought to present a significant hazard in the quantities present. No systematic Samarium toxicity data is available. This material is classified as a flammable solid and may be readily ignited if exposed to a flame or other sources of ignition. It is supplied under an inert atmosphere and should be stored in similar conditions.
