3 Hazard identification
Potential heath effects
Eye: Irritation; fragment in cornea may cause cataracts.
Inhalation: Low immediate health risk by inhalation.
Skin: Irritation; possible flu-like symptoms.
Ingestion: May be moderately irritating to the stomach lining. Can cause irritation of upper
respiratory tract, headache, nausea, vomiting, diarrhoea, chills, fever and aching muscles.
Medical conditions aggravated: Chronic respiratory disease, skin diseases, and Wilson’s
disease..
Chronic: Respiratory disease; lung, heart, kidney damage possible.
4 First aid measures
Eye contact: Remove fragments and flush eyes with water.
Inhalation: Remove from exposure.
Skin Contact: Wash off thoroughly with water. Remove contaminated clothing and wash before
re-use. Get medical aid if irritation develops or persists.
Ingestion: Induce vomiting if victim is conscious.
Notes to physician: Individuals with Wilson’s disease are more susceptible to chronic copper
poisoning.

5 Fire-fighting measures
Special risks
Flammable
Hazardous combustion products: Toxic metal fumes
Fine tin and copper powder is a moderate fire hazard. For tin and copper powder fires do not
use water. Tin and copper react violently with acetylene, ammonium nitrate, bromates,
chlorates, iodates, chlorine, bromine, (Cl2+OF2), chlorine trifluoride, bromine fluoride, ClF2,
ethylene oxide, fluorine, hydrogen peroxide, hydrazine mononitrate, hydrazoic acid, hydrogen
sulphide, lead azide, potassium peroxide, sodium azide, sodium peroxide, cupric nitrate and
sulphur.
Suitable extinguishing media
6 Accidental release measures
Wear appropriate protective clothing.
If material is molten allow to cool and solidify.
Observing precautions in the protective equipment section. Sweep up, then place into a
suitable container for disposal. Avoid generating dusty conditions.
7 Handling and storage
Handling:
Avoid conditions which create toxic fumes of dust. Wash exposed skin after handling material.
Storage:
Store in a tightly closed container. Store in a cool, dry well ventilated area away from
incompatible substances.
8 Exposure controls, personal protection
As appropriate to the situation and the quantity handled.
Respirator: NIOSH/MSHA approved respirator if toxic fumes are present.
Ventilation: Local exhaust if toxic fumes are present.
Gloves:
Eye protection: Safety glasses if particles become airborne.
