EMERGENCY OVERVIEW: When this product is used for it’s intended purpose, fumes and
gases produced as a by product can be hazardous to health.
Aggravation of pre-existing respiratory or allergic conditions may occur in some workers.
Arc rays can injure eyes and burn skin. Electric shock can kill.
Potential Health Effects
Eye: No special hazard risk under normal use. Dusts or particulates may cause mechanical
irritation including pain, tearing, and redness. Scratching of the cornea can occur if eye is
rubbed. Fumes may be irritating. Contact with the heated material may cause thermal burns.
Skin: No special hazard risk under normal use. Dusts or particulates may cause mechanical
irritation due to abrasion. May cause skin irritation in sensitive individuals. Contact with heated
material may cause thermal burns.
Ingestion: Ingestion is an unlikely route of exposure; no hazard in normal industrial use.
Swallowing of excessive amounts of the dust may cause irritation, nausea, and diarrhoea.
Inhalation: No special hazard risk under normal use. Dusts may cause irritation of the nose,
throat, and lungs. Excessive inhalation of metallic fumes and dusts may result in metal fume
fever, an influenza-like illness.
Chronic: Respiratory tract irritation, metal fume fever, eye irritation. Long term repeated
exposures to excessive fume concentrations may lead to intoxication, including kidney disease,
anemia, nervous disorders, birth defects and nasal and lung cancer.
Eyes: In case of overexposure to dusts or fumes, immediately flush eyes with plenty of water
for at least 15 minutes occasionally lifting the eye lids. Seek medical attention if irritation
persists. Thermal burns should be treated as medical emergencies.
Skin: In case of overexposure to dusts or particulates, wash with soap and plenty of water.
Seek medical attention if irritation develops or persists.
Ingestion: Seek medical aid. Do not induce vomiting.
Inhalation: If inhaled, remove to fresh air. Seek medical attention if symptoms develop.

8. Storage and Handling
General Information: As in any fire, wear self-contained pressurised breathing apparatus and
full protective gear. This material is not flammable. However, welding arc and sparks can ignite
combustibles. Grinding or other machining operations can produce fine particulate dust that
may explode in the presence of a strong ignition source. During a fire,irritating and highly toxic
gases may be generated by thermal decomposition or combustion.
Extinguishing Media: Never use water as an extinguishing agent around molten or smoldering
metal. Water will react violently around any molten metal. Use dry chemical, CO
2
or sand.
General Information: Use proper personal protective equipment as indicated in Section 9.
Spills/Leaks: Sweep up and place in suitable containers for recycle or disposal. Spilled or
released at long industrial condition: Remove ignition sources, Keep away from heat and flame,
evacuate area. Avoid breathing dust, vapour, smoke. Wear protective equipment. Shut off
source of the leak only if it is easy to do so. Keep spilled material out of sewers, ditches and
bodies of water.
Handling: In accordance with good industrial practice, handle with care and avoid unnecessary
personal contact. Wash thoroughly after handling. Use with adequate ventilation. Minimise dust
generation and accumulation. Do not eat, drink or smoke while handling the product. Keep
away from sources of ignition.
Storage: Keep away from heat and flame. Store in a cool, dry place away from incompatible
substances.
Engineering Controls: Facilities storing or utilising this material should be equipped with an
eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations
low.
Individual Protection for Industrial Use:
Eyes: Wear appropriate protective eye glasses or chemical safety goggles.
Skin: For prolonged or repeated contact, use protective gloves.
Clothing: Choose body protection according to the amount and concentration of the dangerous
substance in the workplace.
Respirators: Follow the European Standard EN 149. Use a European Standard EN 149
approved respirator if exposure limits are exceeded, or if irritation or other symptoms are
experienced.
