SECTION 3. HAZARDS IDENTIFICATION
Emergency Overview: Colorless, odorless granules. Not flammable or explosive, but will decompose in extreme heat to
produce toxic sulfur oxide gas and zinc oxide fume. The granular solid or dust is relatively non-toxic to humans and poses little
immediate hazard to emergency response personnel but is freely soluble in water and can pose a threat to watercourses.
Potential Health Effects: May irritate eyes, skin and respiratory tract. If dusty it may cause breathing difficulty and irritation of
mucous membranes. Ingestion may cause strong stomach cramps and diarrhea and may induce spontaneous vomiting. Chronic
health hazards include stomach irritation, abdominal cramps and nausea. Zinc sulfate monohydrate is not considered a
carcinogen by OSHA, NTP, IARC, ACGIH or the EU (see Toxicological Information, Section 11).
Potential Environmental Effects: This product is highly water soluble and is toxic to fish and other aquatic life. It can also be
toxic to plant life and other terrestrial organisms at elevated concentrations in soils (see Ecological Information, Section 12).

SECTION 4. FIRST AID MEASURES
Eye Contact: Do not allow victim to rub eye(s). Let the eye(s) water naturally for a few minutes. If particle/dust does not
dislodge, flush with lukewarm, gently flowing water for 5 minutes or until particle/dust is removed, while holding eyelid(s) open. If
irritation persists, obtain medical attention. DO NOT attempt to manually remove anything stuck to the eye.
Skin Contact: Remove contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Quickly and gently blot or
brush away excess chemical. Wash gently and thoroughly with lukewarm gently flowing water and non-abrasive soap for 5
minutes. If irritation persists, repeat flushing. Obtain medical advice. Completely decontaminate clothing, shoes and leather
goods before reuse or else discard.
Inhalation: If symptoms are experienced, remove source of contamination or move victim to fresh air. Obtain medical advice.
Ingestion: Never give anything by mouth if victim is rapidly losing consciousness, or is unconscious or convulsing. Have victim
rinse mouth thoroughly with water. DO NOT INDUCE VOMITING. Have victim drink 2 鈥? 8 oz. (60 鈥? 240 ml) of water. Zinc sulfate
is an emetic and may cause vomiting. If vomiting occurs naturally, have victim rinse mouth with water again. Obtain medical
advice and bring a copy of this MSDS.
SECTION 5. FIRE FIGHTING MEASURES
Fire and Explosion Hazards: Zinc sulfate does not burn or support combustion.
Extinguishing Media: Use any means of extinction appropriate for the surrounding fire conditions such as water spray, carbon
dioxide, dry chemical, or foam.
Fire Fighting: Toxic fumes of sulfur dioxide may result from combustion. As with any fire, 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 facepiece mask. Do not use water directly on material. Do not allow water run-off to enter sewers or watercourses.
Flashpoint and Method: Not Applicable.
Upper and Lower Flammable Limit: Not Applicable.
Autoignition Temperature: Not Applicable.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Procedures for Cleanup: Stop release if possible to do so safely. Contain spill, isolate hazard area, and deny entry. Sweep up
or vacuum. Place contaminated material in suitable, labeled containers for final disposal. Dispose of waste material consistent
with the requirements of waste disposal authorities.
Personal Precautions: Gloves and coveralls or other protective clothing are recommended for persons responding to an
accidental release (see also Section 8). Close-fitting safety goggles may be necessary in some circumstances to prevent eye
contact.
Environmental Precautions: This product can pose a threat to the environment. Contamination of soil and water should be
prevented. Keep spillage and runoff from storage areas from entering soil, streams or sewers.
SECTION 7. HANDLING AND STORAGE
Store in cool, dry, well-ventilated area away from incompatible substances. Protect from physical damage. It is good practice to
keep container closed when not in use. Avoid generating dust and the release of dust into the workplace. Good housekeeping is
important to prevent accumulations of dust. Always practice good personal hygiene. Refrain from eating, drinking, or smoking in
work areas.
SECTION 8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Protective Clothing: The hazard potential of this material is low. Where there is large scale use of this material and significant
potential for worker contact, gloves and long sleeved work clothes or disposable coveralls may be necessary. Eye protection
should be worn where dust is generated and there is a potential that eye contact may occur.
Ventilation: Use adequate local or general ventilation where necessary to maintain the concentrations of zinc sulfate dust well
below the recommended occupational exposure limits for general Particulates, Not Otherwise Specified (PNOS).
Respirators: Where dust or 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: This material is stable and not considered reactive under normal temperatures and pressures.
Hazardous polymerization or runaway reactions will not occur.
Incompatibilities: None have been identified to date. Avoid excessive heating that may lead to decomposition of the material.
Hazardous Decomposition Products: High temperature operations such as oxy-acetylene cutting, electric arc welding or
severe overheating will generate zinc oxide fume which, on inhalation in sufficient quantity, can produce metal fume fever.
Under such conditions, sulfur dioxide will also be generated and can cause respiratory distress.
SECTION 11. TOXICOLOGICAL INFORMATION
General: In the form in which this product is sold it is relatively non-toxic. The major route of exposure would be through the
generation and inhalation of airborne dust and especially the generation of zinc oxide fume through thermal decomposition.
Acute:
Skin/Eye: Direct contact may cause local irritation of the eyes or skin but would not cause tissue damage. Eye contact with
solutions (>1%) may cause the appearance of white flecks on the lens of the eye. Dust or fume from burning or welding
operations may also cause local irritation.
Inhalation: Acute inhalation may result in irritation but is not expected to cause significant harmful effects. Symptoms may
include discomfort, coughing, tingling sensation, sneezing and/or shortness of breath and wheezing. Extreme heating of zinc
sulfate monohydrate will generate zinc oxide fume. If inhaled, this fume can result in the condition called metal fume fever. The
symptoms of metal fume fever will occur within 3 to 10 hours of exposure, 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: Ingestion of large doses can cause anemia and stomach symptoms. Zinc sulfate is very astringent, and when
ingested in excessive quantities, can irritate the stomach, resulting in abdominal pain, nausea, diarrhea and spontaneous
vomiting.
Chronic: In general, zinc is considered to be a low toxicity metal. Zinc is a very important trace element for humans and the
body regulates the amount of zinc stored by decreasing absorption and increasing excretion when intake is increased. Industrial
experience has not identified any significant chronic effects from zinc sulfate to date. Zinc sulfate is not listed as a carcinogen 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
This product has high water solubility and its zinc contents are directly bioavailable. The zinc in particular may be toxic to aquatic
organisms, especially fish, with water hardness, pH and dissolved organic carbon levels being regulating factors. In terrestrial
systems, the mobility of zinc in soil and its degree of bioaccumulation in organisms is dependent on soil chemical conditions.
