Precautionary statements

Obtain special instructions before use Do not handle until all safety precautions have been read and understood Avoid breathing dust or fume Wear protective gloves, protective clothing, eye, and face protection Contaminated work clothing should not be allowed out of the workplace If exposed or concerned, get medical advice/attention See Section 11 for more detailed information on health effects and symptoms 3. FIRST-AID MEASURES These measures apply primarily to the byproducts produced during thermal spray or welding. Inhalation: Move exposed person to fresh air. Keep the person warm and at rest. If not breathing or if breathing is irregular or if respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel. It may be dangerous to the person providing aid to give mouth-to-mouth resuscitation. Obtain medical attention if unconscious, place in recovery position and get medical attention immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband. Ingestion: Wash out mouth with water. Remove dentures if any. Move exposed person to fresh air. Keep the person warm and at rest. If material has been swallowed and the exposed person is conscious, give small quantities of water to drink. Stop if the exposed person feels sick as vomiting may be dangerous. Do not induce vomiting unless directed to do so by medical personnel. If vomiting occurs, the head should be kept low so that vomit does not enter the lungs. Obtain medical attention if symptoms occur. Never give anything by mouth to an unconscious person. If unconscious, place in recovery position and get medical attention immediately. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband. Skin Contact: Flush contaminated skin with plenty of water. Remove contaminated clothing and shoes. Obtain medical attention if symptoms occur. Wash clothing before reuse. Clean shoes thoroughly before reuse. .Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Check for and remove any contact lenses. Get medical attention if irritation occurs. Protection of First Aiders: No action shall be taken involving any personal risk or without suitable training. See Section 11 for more detailed information on health effects and symptoms. 4. FIRE-FIGHTING MEASURES This section applies primarily to the wire as supplied. Extinguishing Media Suitable: Use an extinguishing agent suitable for the surrounding fire. Not Suitable: None known Special Exposure Hazards: No specific hazard Hazardous Thermal Decomposition Products: Some metallic oxides Special Protective Equipment for Fire-Fighters: Fire-fighters should wear appropriate protective equipment and self contained apparatus (SCBA) with a full face-piece operated in positive pressure mode. 5. ACCIDENTAL RELEASE MEASURES These measures apply to the wire as supplied and the byproducts produced during the thermal spray or welding process. Personal Precautions: Immediately contact emergency personnel. Keep unnecessary personnel away. Use suitable protective equipment. Environmental Precautions: Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains and sewers. Methods for Cleaning Up: Use appropriate tools to transfer the spilt solid to a convenient waste disposal container. Recycle if possible. 6. HANDLING AND STORAGE This section applies primarily to the wire as supplied. Handling: Eating, drinking and smoking should be prohibited in areas where this material is handled, stored and processed.

Additional information

A portion of metallic chromium may be converted during the welding process to hexavalent chromium. Hexavalent chromium is classified as an IARC Group 1 carcinogen. NTP classifies hexavalent Chromium as Known to be Carcinogenic. ** A portion of nickel may be converted during the thermal spray process to nickel compounds which are classified as an IARC Group 1 Carcinogen. NTP classifies nickel compounds as Known to be Carcinogenic. which are classified as an IARC Group1 Carcinogen. NTP classifies nickel compounds as Known to be Carcinogenic. Monitoring Procedures: If this product contains ingredients with exposure limits, personal, workplace atmosphere or biological monitoring may be required to determine the effectiveness of ventilation or other control measures and/or the necessity to use respiratory protective equipment. Reference should be made to European Standard EN 689 for methods for the assessment of exposure by inhalation to chemical agents and national guidance documents for methods for the determination of

Hazardous Ingredients

Exposure Controls Occupational Exposure: Use process enclosures, local exhaust ventilation or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fumes or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit. Respiratory Protection: Use a properly fitted, air-purifying or air-fed respirator complying with an approved standard if a risk assessment indicates this is necessary. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product and the safe working limits of the selected respirator. Hand Protection: Gloves should be worn to minimize contact. During the thermal spray process, heat insulated gloves are recommended. Eye Protection: Safety glasses or goggles are recommended when handling this material. During the thermal spray process, safety goggles and dark lenses must be worn. Skin Protection: Personal protective equipment for the body should be selected based on the task being performed and the risks involved and should be approved by a specialist before handling this product. Hearing Protection: During the thermal spray process, the operator and other personnel close to the spray operation must be protected from excessive noise. Use hearing protection that meets local standards. Hygiene Measures: Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period. Appropriate techniques should be used to remove potentially contaminated clothing. Wash contaminated clothing before reusing. Ensure that eyewash stations and safety showers are close to the workstation location. 8. PHYSICALAND CHEMICAL PROPERTIES This section applies primarily to the wire as supplied.
