Hazardous components
1. Zinc (foil rod, slug)

Index no. 030-001-01-9
SECTION 4: First-aid measures
4.1 Description of necessary first-aid measures
General advice Zinc is essentially non-toxic to humans. However, zinc oxide fumes may
cause mild local irritation to
eyes, nose, throat and upper airways. Acute over-exposure to zinc oxide
fume may cause metal fume fever, characterized by flu-like
symptoms such as chills, fever, nausea, and vomiting which may be delayed
3 – 10 hours in onset. In most cases, dermal exposure
to zinc or zinc compounds does not result in any noticeable toxic effects.
Zinc is not listed as a carcinogen by OSHA, NTP, IARC,
ACGIH or the EU (see Toxicological Information, Section 11).
If inhaled Symptoms: Coughing and irritation in heavy dust clouds. If symptoms are
experienced remove source of
contamination or move victim from exposure area to fresh air immediately
and obtain medical advice. NOTE: Metal fume fever
may develop 3-10 hours after exposure to zinc oxide fumes. If symptoms of
metal fume fever (flu-like symptoms) develop, obtain
medical attention.
In case of skin contact Symptoms: Soiling of skin. No health effects expected. If irritation does
occur, rinse with lukewarm, gently flowing
water for 5 minutes or until the product is removed. If skin irritation occurs or
you feel unwell, get medical advice/attention.
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.
In case of eye contact Symptoms: Mild eye irritation, redness. Do not rub eye(s). Let the eye(s)
water naturally for a few minutes. Look
right and left, then up and down. If particle/dust does not come out,
cautiously rinse eye(s) with lukewarm, gently flowing water for
5 minutes or until particle/dust is removed, while holding eyelid(s) open. If
eye irritation persists, get medical advice/attention. DO
NOT attempt to manually remove anything from the eye.

intervention is indicated as this material is not
likely to be hazardous by ingestion. However, if you are concerned or you
feel unwell, obtain medical advice.

Not available
Further information
Massive metal is difficult to ignite and is not considered a serious fire hazard. However, finelydivided
metallic dust may form flammable or explosive dust clouds when dispersed in the air at high concentrations and
exposed
to heat, flame, or other ignition sources. Bulk dust in a damp state may heat spontaneously and ignite on exposure
to air.
Contact with acids and alkali hydroxides results in evolution of hydrogen gas which is potentially explosive. Mixtures
with
potassium chlorate or fused ammonium nitrate may explode on impact.
SECTION 6: Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
Control source of release if possible to do so safely. Clean up spilled material immediately observing
precautions in Section 8, Personal Protection. Molten metal should be allowed to cool and harden before cleanup.
Once
solidified wear gloves, pick up and return to process. Powder or dust should be cleaned up by sweeping/shoveling,
etc. Solid
metal is recyclable. Return uncontaminated spilled material to the process if possible. Place contaminated material
in clean, dry, suitably labelled containers for later recovery or disposal. Treat or dispose of waste material in
accordance with all local,
state/provincial, and national requirements.

SECTION 7: Handling and storage
7.1 Precautions for safe handling
Store zinc in a DRY covered area, separate from incompatible materials. Zinc ingots suspected of containing
moisture should be

THOROUGHLY DRIED before being added to a molten bath. Ingots may contain cavities that collect moisture.
Entrained
moisture will expand explosively when immersed in a molten bath.

8.2 Appropriate engineering controls
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.

10.1 Reactivity
Not Reactive
10.2 Chemical stability
Stable
10.3 Possibility of hazardous reactions
Massive metal is stable and not considered reactive under normal temperatures and pressures.
Hazardous polymerization or runaway reactions will not occur. Zinc metal slowly becomes covered with a white
coating of a
hydrated basic zinc carbonate on exposure to moist air. Fine, condensed zinc dust or powder may heat
spontaneously and ignite
on exposure to 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 is heated with sulphur. Powdered zinc will become incandescent or ignite
in the
presence of fluorine, chlorine, bromine or interhalogens (e.g., chlorine trifluoride). Powdered zinc can also react
explosively with
halogenated hydrocarbons if heated. Mixtures with potassium chlorate or fused ammonium nitrate may explode on
impact.

SECTION 11: Toxicological information
Information on toxicological effects
Acute toxicity
Zinc, especially in the metal form, is relatively non-toxic. However, it can react with other materials, such as oxygen
or
acids, to form compounds that can be potentially toxic. The primary route of exposure would be through the
generation and
inhalation of zinc oxide fume.
