SECTION 3. HAZARDS IDENTIFICATION
Emergency Overview: A silver metal that does not burn in bulk but may form explosive mixtures if dispersed in air as a fine
powder. Contact with acids or alkalis may generate flammable hydrogen gas that can accumulate in poorly-ventilated areas. Do
not use water or foam in fire fighting. This product is relatively non-toxic and does not pose an immediate hazard to the health of
emergency response personnel or to the environment in an emergency situation.
Potential Health Effects: Pure zinc, tin and copper are relatively non-toxic to humans. This product may cause mild local irritation
to eyes, nose, throat and upper airways, particularly if the product is heated to the point of fuming. Acute over-exposure to zinc
oxide fume may cause metal fume fever, characterized by flu-like symptoms such as chills, fever, nausea, and vomiting. Zinc, tin
and copper are not listed as carcinogens by OSHA, NTP, IARC, ACGIH or the EU. (see Toxicological Information, Section 11)
Potential Environmental Effects: In the form in which this product is sold it does not present a significant threat to the
environment. However, contamination of soil and water should be prevented. (see Ecological Information, Section 12)
EU Risk Phrase(s): Not applicable - zinc, tin and copper are not dangerous substances.
SECTION 4. FIRST AID MEASURES
Eye Contact: Flush with warm, running water, including under the eyelids, for at least 15 minutes. If irritation persists seek medical
attention.
Skin Contact: Dust: Remove contaminated clothing and wash affected area with soap and warm water. Seek medical attention if
irritation develops or persists. Molten Metal: Flush contact area to solidify and cool but do not attempt to remove encrusted material
or clothing. Cover burns and seek medical attention immediately.
Inhalation: Remove victim from exposure area to fresh air immediately. If breathing has stopped, give artificial respiration.
Medical oxygen may be administered, if available, where breathing is difficult. Keep affected person warm and at rest. Seek
medical attention immediately.
Ingestion: If victim is conscious, dilute stomach contents with 2-4 cupfuls of water or milk. Do not induce vomiting. Seek medical
attention immediately and bring a copy of this MSDS. Never give anything by mouth to an unconscious person.
SECTION 5. FIRE FIGHTING MEASURES
Fire and Explosion Hazards: Massive metal is not flammable; however, finely-divided metallic dust or powder may form
flammable or explosive dust clouds when mixed with air. Contact with acids and alkali hydroxides results in evolution of hydrogen
gas which is potentially explosive.
Extinguishing Media: Do NOT use water or foam on molten metals. Apply dry chemical, sand, or special powder extinguishing
media. Water may be ineffective for extinguishing a fire but should be used to keep fire-exposed containers cool.
Fire Fighting: If possible, move material from fire area and cool material exposed to flame. Apply dry chemical, sand, or special
powder extinguishing media. Zinc and tin oxide fumes may evolve in fires. Fire fighters should be fully trained and wear full
protective clothing including an approved, self-contained breathing apparatus which supplies a positive air pressure within a full
face-piece mask.
Flashpoint and Method: Not Applicable.
Upper and Lower Flammable Limit: Lower Flammable Limit (Zinc Dust): 500 g/m3; Upper Flammable Limit: Not Applicable.
Autoignition Temperature: Approximately 630 - 650潞C (dust cloud in air).
SECTION 6. ACCIDENTAL RELEASE MEASURES
Procedures for Cleanup: Solid metal is recyclable. Vacuuming recommended for accumulated metal dust. Molten metal should
be allowed to solidify prior to clean-up. Return uncontaminated spilled material to process if possible. Place contaminated and non-
recyclable material in suitable labeled containers for later disposal. Treat or dispose of waste material in accordance with all local,
regional and national requirements, as applicable.

Personal Precautions: Standard protective equipment used in soldering operations: heat-resistant gloves, approved respirator
where fume/dust are present, safety glasses/welding goggles, protection from hot-metal splash, safety-type boots.
Environmental Precautions: Zinc, tin and copper in the metallic forms present in this product have limited bioavailability and pose
no immediate ecological risk. However, good management practices should be applied in the storage and use of the product.
SECTION 7. HANDLING AND STORAGE
庐
Store Galva鈥uard in a DRY covered area, separate from incompatible materials. Always practice good personal hygiene. Refrain
from eating, drinking, or smoking in work areas. Thoroughly wash hands before eating, drinking, or smoking in appropriate
designated areas. No special packaging materials are required.
EU Safety Phrase(s): Not applicable - zinc, tin and copper are not dangerous substances.
SECTION 8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Protective Clothing: Gloves and coveralls, shop coat or other work clothing with long sleeves are recommended to prevent
庐
prolonged or repeated direct skin contact when Galva鈥uard is processed. Eye protection should be worn where fume or dust is
generated. Respiratory protection may be required where oxide fume is generated. Where hot or molten metal is handled, heat
resistant gloves, goggles or face-shield, and clothing to protect from hot metal splash should be worn. Safety type boots are
recommended.
Ventilation: Use adequate local or general ventilation to maintain the concentration of zinc and tin oxide fumes in the working
environment well below recommended occupational exposure limits. Supply sufficient replacement air to make up for air removed
by the exhaust system.
Respirators: Where zinc or tin oxide fumes are generated and cannot be controlled to within acceptable levels by engineering
means, use appropriate NIOSH-approved respiratory protection equipment (a 42CFR84 Class N, R or P-95 particulate filter
cartridge).

SECTION 10. STABILITY AND REACTIVITY
Stability and Reactivity: Product is stable under normal temperatures and pressures. Fine, condensed zinc or tin dust or powder
can ignite spontaneously in the presence of air when damp. Zinc metal will react with acids and strong alkalis to generate hydrogen
gas. A violent, explosive reaction may occur when powdered zinc or tin is heated with sulphur or halogenated hydrocarbons.
Mixtures with potassium chlorate or ammonium nitrate may explode on impact.
Incompatibilities: Always keep product dry. Avoid contact with strong acids or alkalis or elemental sulphur dust. Incompatible
with strong oxidizing agents such as chlorine, fluorine, bromine, sodium potassium or barium peroxide, sodium or potassium
chlorate or fused ammonium nitrate. Acidic arsenic or antimony solutions in contact with Galva鈥uard庐 metal or dust may generate
highly toxic arsine or stibine gas.
Hazardous Decomposition Products: High temperature operations such as oxy-acetylene cutting, electric arc welding or
overheating a molten bath will generate metal oxide fume which, on inhalation in sufficient quantity, can produce metal fume fever.

SECTION 11. TOXICOLOGICAL INFORMATION
General: In the metallic form in which it is sold this product is relatively non-toxic. The major route of exposure would be through
the generation and inhalation of metal oxide fume, particularly zinc oxide.
Acute:
庐
Skin/Eye: Contact with Galva鈥uard dust or fume may cause local irritation but would not cause tissue damage.
庐
Inhalation: If excessive quantities of Galva鈥uard fume are inhaled, it can result in the condition called metal fume fever. The
symptoms of metal fume fever will occur within 3 to 10 hours, and include immediate dryness and irritation of the throat, tightness of
the chest, and coughing which may later be followed by flu-like symptoms of fever, malaise, perspiration, frontal headache, muscle
cramps, low back pain, occasionally blurred vision, nausea, and vomiting. The symptoms are temporary and generally disappear,
without medical intervention, within 24 to 48 hours of onset. There are no recognized complications, after affects, or chronic affects
that result from this condition.
Ingestion: When ingested in excessive quantities, zinc and tin can irritate the stomach resulting in possible nausea and vomiting.
Chronic: There is no chronic form of metal fume fever but in rare instances an acute incident may be followed by complaints such
as bronchitis or pneumonia. Some workers may develop a short-term immunity (resistance) so that repeated exposure to zinc oxide
fumes does not cause metal fume fever. This immunity (resistance) however is quickly lost after short absences from work
(weekends or vacations). Workers exposed to finely-divided metallic zinc for up to 35 years revealed no acute or chronic illnesses
attributable to zinc. Chronic exposure to tin dust or fumes is known to cause a benign pneumoconiosis (Stannosis) characterized by
progressive X-ray changes of the lung while exposure continues, but without any distinctive fibrosis or scarring of the lungs and
without any evidence of disability. Zinc, tin and copper are not listed as human carcinogens by the Occupational Safety and Health
Administration (OSHA), the National Toxicology Program (NTP), the International Agency for Research on Cancer (IARC), the
American Conference of Governmental Industrial Hygienists (ACGIH) or the European Union (EU).
SECTION 12. ECOLOGICAL INFORMATION
Zinc and copper in the metallic forms have limited bioavailability and pose no immediate ecological risk. However, use of this
product or processes in the environment may increase their bioavailability. In aquatic systems, zinc and copper can be toxic and
can bioaccumulate in both plants and animals with pH, hardness and dissolved organic compounds being regulating factors. Zinc
and copper can also bioaccumulate in terrestrial plants, soil invertebrates and mammals in accordance with the species and soil
properties. Tin, as a metal, has limited bioavailability and poses no immediate ecological risk. Its compounds are only moderately
toxic in the environment.
