Section 2. HAZARDS IDENTIFICATION

2.1 Classification of the substance or mixture
Classification according to Regulation (EC) 1271/2008 [CLP] applicable
2.2 Label elements
2.3 Other hazards Note: When preparing (grinding) and using these electrodes as part of the welding process additional potential hazards are likely: Grinding: Toxic dusts. Ensure adequate dust extraction, ventilation and dust disposal When the product is used in the welding process the most important hazards are: Overexposure to fumes and gases from welding can be dangerous to health. Watch out for splatter, hot metal and slag. It may cause skin burn and cause fire. Arc rays can injure eyes and burn skin. Electric shock can kill. Avoid touching live electrical parts. Section 3.

Section 4. FIRST AND MEASURES

4.1 Description of first aid measures
Inhalation
IF INHALED: If breathing is difficult, remove to fresh air and keep at rest in a position comfortable for breathing. Call a physician if symptoms occur. Skin contact
Burns should be treated by a doctor. Eye contact
IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Burns from radiation, see doctor. Ingestion
Contact a doctor if more than an insignificant amount has been swallowed.
4.2 Most important symptoms and effects, both acute and delayed
Inhalation
Inhalation of vapours may cause irritation of the respiratory system in very susceptible persons.

Section 6. ACCIDENTAL RELEASE MEASURES
6.1 Personal precautions, protective equipment and emergency procedures General ventilation and local fume extraction must be adequate to keep fume concentrations within safe limits. Use respiratory equipment when welding in a confined space. Wear protective clothing and eye protection appropriate to arc welding. Skin contact should be avoided to prevent possible allergic reactions. 6.2 Environmental precautions Try to prevent the material from entering drains or water courses. Waste, dust filters and recipients are to de disposed of in a safe and secure way, according to respective national regulations in force. Grey washing or grinding water is to be captured and disposed of. 6.3 Methods and material for containment and cleaning up 6.4 Reference to other sections For Personal protection see section 8. For Disposal see section 13. For Environmental precautions see section 12. For Precautions for safe handling see 7.1. Section 7. HANDLING AND STORAGE
7.1 Precautions for safe handling Preventive handling precautions
Ensure adequate ventilation for the welder and others. Use respiratory equipment when welding in a confined space. Wear protective clothing and eye protection appropriate to arc welding. Remove all flammable materials and liquids before welding. General hygiene
Wash hands before breaks and immediately after handling the product. 7.2 Conditions for safe storage, including any incompatibilities Store welding consumables inside a room without humidity. Do not store welding consumables directly on the ground or beside walls. Store away from chemical substances like acids which could cause chemical reactions. 7.3 Specific end use(s) Welding process.

Carcinogenicity: May cause cancer The classification information above relates to the fume during use.
Section 11. TOXICOLOGICAL INFORMATION

11.1 Information on toxicological effects
Conditions to avoid: none in the form supplied When welding, fumes and gases generated can be dangerous to health. Acute toxicology
This product does not feature an acute oral, dermal toxicity or toxicity through inhalation Irritation
Corrosive effects
May cause sensitisation by skin contact Welding fumes are possibly carcinogenic to humans Repeated dose toxicity
Finding after intratracheal application of 50mg tungsten dust per week during 3 weeks on guinea pigs lead to the conclusion that the substance is relatively inert. Still an effect on the pulmonary tissue could be proved which must not be neglected. Reproductive toxicity
Section 12. ECOLOGICAL INFORMATION
12.1 Toxicity The welding process can effect the environment if fume is released directly into the atmosphere. 15.6mg/L (rainbow trout, oncorhynchus mykiss,28d) Aluminiumoxide: >100 mg/l Salmo trutta IC Amphibians 72h: 2.9mg/L (toad,gastrophryne carolinensis, 7d) 12.2 Persistence and degradability Tunsten forms a series of oxohalogenides (e.g. WOCL ) SAFETY DATA SHEET
