If breathing difficulties occur, administer oxygen inhalation. If breathing has stopped, immediately administer artificial respiration and get medical advice/attention. If irritation or rash persists, get medical advice and attention. IFON SKIN If dust from grinding scraps is contacted with skin, take off contaminated clothing and rinse the affected area with soapy water thoroughly. If itTitation or rash persists, get medical advice/attention. IF IN EYES If dust from grinding scraps is in eyes, immediately wash away with clean water. If irritation persists, get medical advice/attention.

Most important symptoms/effects, acute and delayed; May cause an allergic skin reaction May cause allergy or asthma symptoms or breathing difficulties if inhaled May cause respiratory irritation Suspected of causing genetic defects Suspected of causing cancer Suspected of damaging fertility or the unborn child Causes damage to respiratmy system, kidney May causes damage to systemic toxicity Causes damage to respiratmy system through prolonged or repeated exposure Indication of immediate medical attention and special treatment needed, if necessary; No information Section 5: Fire-fighting measu_::.r:..:e::.s_________________ _ Suitable (and unsuitable) extinguishing media; Suitable extinguishing media: To extinguish the fire of dusts resulting from grinding, use dry sand, dry dolomite, ABC type (general, oil, electric fire) powder extinguishers or water. Unsuitable extinguishing media No water allowed for the dust containing cut powders of light metal such as magnesium and aluminum. Specific hazards arising from the chemical; General caution; powdered materials may cause dust explosions under certain conditions. Special protective equipment and precautions for fire-fighters; Dusts resulting fi·om grinding are very fine and under the specific conditions in which the dusts are mixed with grinding oil with low flash point, it is possible to become pyrophoric. If dusts under very flammable conditions are dispersed in the air, it is possible to explode. In such cases, look to your own safety first and then take necessary fire-fighting measures. In fighting a fire, wear a dust-proof respirator or respiratory protective equipment. Section 6: Accidental release measures Personal precautions, protective equipment, and emergency procedures; It is recommended that someone who cleans grinding scraps or dusts should wear clothing and respiratory protective equipment to minimize exposure. Dispose of dusts as industrial wastes and prevent release in water systems. Methods and materials for containment and cleaning up; Cemented Carbide, Cemented Carbide Tool, Coated Cemented Carbide, and Coated Cemented Carbide Tool DUET Industrial Co., LTD. ~ Japan PageS of 11 Date of issue: 22"d June, 2015 If there are dusts from resulting from grinding and mechanical processing, isolate the area and remove with a cleaner equipped with a filter which can take up fine particles very efficiently. If appropriate removing methods are not available, sweep with water sprayers or wet mops. Section 7: Handling and storage Precautions for safe handling Protective measures: Install appropriate equipment and wear suitable protective apparatus described in Section 8: Exposure controls/personal protection. Cemented Carbide is stable and has little effect on health. However prolonged or repeated exposure to the dust or grinding liquid containing cobalt or nickel may cause rough skin. As the specific gravity of Cemented Carbide is great, handle as a large-sized product or in the case of large quantity, as a heavy product. In grinding or mechanical processes, provide local exhaust ventilation and use personal protective equipment to minimize exposure to human body, due to the possibilities of the disperse of dust containing cobalt or nickel. Do the same way for grinding sludge. Regular physical checkups are recommended. Advice on general occupational hygiene: Wash hands thoroughly before eating, drinking, and smoking. Do not eat, drink, and smoke in the handling area. Conditions for safe storage! including any incompatibilities Technical measures: In the storage area, install adequate light and ventilation systems to handle hazardous materials. Incompatible materials: Oxidizing substances (Hydrogen
