2.1 Classification of the substance or mixture
Classification according to Regulation (EC) No. 1272/2008 [CLP/GHS] Zinc metal in massive form is not classified as hazardous. Classification according to Directive 67/548/EEC [DSD] The product is not classified as dangerous according to Directive 1999/45/EC and its amendments. See Section 11 for more detailed information on health effects and symptoms. See Section 16 for the full text of the R phrases or H statements declared above. 2.2 Label elements

2.3 Other hazards
Other hazards which do
: Hazards may be created by change in the physical condition of the metal, e.g. during melting. On result in classification
heating zinc metal above 750oC freshly formed fumes of zinc oxide will be evolved. Zinc oxide fume is associated with the onset of Metal Fume Fever, a reversible illness with flu-like symptoms. If the lead content of the metal is over 1% and the physical state of the metal is altered, and dust or fumes are generated, then the hazard statements are harmful by inhalation and if swallowed. Danger of cumulative effects. Zinc may be taken up and bio-accumulated in invertebrates and other 3: Composition/information on ingredients

Type
[1] Substance classified with a health or environmental hazard.
Occupational exposure limits, if available, are listed in Section 8. 4: First aid measures
4.1 Description of first aid measures
Eye contact
: Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical attention if irritation occurs. Inhalation
: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give Skin Contact
: Wash with soap and water. Cover the irritated skin with an emollient. Get medical attention if irritation Ingestion
: Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If large quantities of this material are swallowed, call a physician immediately. Loosen tight clothing such as a collar, tie, belt or waistband. Protection of first-aiders
4.2 Most important symptoms and effects, both acute and delayed
Potential acute health effects
Eye contact
: No significant irritation expected other than possible mechanical irritation. Inhalation
: Zinc dust is discomforting to the respiratory tract when inhaled and initially acts as a respiratory irritant. Zinc oxide fumes and vapour produced from high temperature processes can produce ‘metal fume fever’. Symptoms include headache, nausea, chills, muscle aches, fever, coughing, chest tightness and a metallic taste in the mouth. The onset of symptoms may be delayed by up to 24 hours after exposure however normally symptoms present between 3 and 10 hours post exposure and can last for approximately 48 hours. Personnel may be particularly susceptible to metal fume fever after a period of non-exposure. Skin contact
: Material may be mildly discomforting to the skin. Zinc may irritate the skin and produce redness and Ingestion
: Not normally a hazard due to the physical form of the product. Material is discomforting to the digestive tract and may cause nausea, vomiting, headache, abdominal discomfort and diarrhea. Convulsion, collapse and unconsciousness and death may occur in severe cases. Over-exposure signs/symptoms

4.3 Indication of any immediate medical attention and special treatment needed
Notes to physician
: Treat symptomatically. Contact poison treatment specialist immediately if large quantities have Specific treatments
5: Firefighting measures
5.1 Extinguishing media
Suitable extinguishing
: Use an extinguishing agent suitable for the surrounding fire. Dry sand or other inert material. Use Unsuitable extinguishing : Water, foam or CO2 extinguishers
5.2 Special hazards arising from the substance or mixture
Hazards from the
substance or mixture
Hazardous combustion
: Zinc + NaOH causes ignition. Oxidation of zinc by potassium proceeds with incandescence. products
Residues from zinc dust /acetic acid reduction operations may ignite after long delay if discarded into waste bins with paper. Incandescent reaction when Zinc and Arsenic or Tellurium, or Selenium are combined. When hydrazine mononitrate is heated in contact with zinc, a flaming decomposition occurs at temperatures a little above its melting point. Contact with acids and alkali hydroxides (sodium hydroxide, postasium hydroxide, calcium hydroxide, etc.) results in evolution of hydrogen with sufficient heat of reaction to ignite the hydrogen gas. Zinc foil ignites if traces of moisture are present. It is water reactive and produces flammable gases on contact with water. Damp zinc metal dust may heat spontaneously and ignite on exposure to air.
5.3 Advice for fire fighters

Special precautions
Special protective
: Clothing for fire-fighters (including helmets, protective boots and gloves) conforming to European equipment
standard EN 469 will provide a basic level of protection for chemical incidents. 6: Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
For non-emergency
: Provide adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Put on personnel
appropriate personal protective equipment. For emergency responders : See Section 8 for information on appropriate personal protective equipment. Follow good industrial

6.2 Environmental precautions
: Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains and sewers. Inform the relevant authorities if the product has caused environmental pollution (sewers, waterways, soil or air).
6.3 Methods and materials for containment and cleaning up
: Move containers from spill area. Vacuum or sweep up material and place in a designated, labeled waste container. Dispose of via a licensed waste disposal contractor. Do not overheat molten zinc. Extracted air containing metallic or metallic oxides should be cleaned before discharge. If product is still hot after casting, cordon off area and allow cooling. If molten product spills, prevent spreading with sand. Solid material should be picked up by shovel or by hand using leather gloves if necessary. Ensure all chips or small particles are picked up and prevented from entering
