INGESTION: Dilute the product immediately with large amounts of water or milk and remove by gastric
lavage unless the victim is already vomiting ( Dreisbach, Handbook of Poisoning, 12th Ed.).
Administration of gastric lavage should be performed by qualified medical personnel. Get medical
attention immediately. Treat symptomatically and supportively. If vomiting occurs, keep head lower than
hips to prevent aspiration.
NOTE TO PHYSICIAN: Antidote: The antidote, for poisoning from zinc salts recommended, is from
Dreisbach, Handbook of Poisoning, 12th Edition. However, the decision as to whether the severity of
poisoning requires administration of any antidote and actual dose required should be made by qualified
medical personnel.
SECTION 5: FIRE FIGHTING MEASURES
FIRE AND EXPLOSION HAZARD: Negligible fire and explosion hazard in dust form when exposed to
heat or flame.
EXTINGUISHING MEDIA: Dry chemical, carbon dioxide, water spray or foam, as appropriate for
surrounding material. For larger fires, use water spray, fog or regular foam (1996 North American
Emergency Response Guidebook, RSPA P 5800.7, Guide Number 171).
FIREFIGHTING: Move product from fire area if you can without risk. Extinguish fire using agent suitable
for type of surrounding fire and/or chemicals. Do not use water directly on material. Avoid breathing
vapors; keep upwind. Dike area to prevent runoff and contamination of water sources.
HAZARDOUS COMBUSTION PRODUCTS: Thermal decomposition may include toxic and hazardous
oxides of zinc and sulfur.
SECTION 6: ACCIDENTAL RELEASE MEASURES
OCCUPATIONAL SPILL: Do not touch spilled material. Pick-up dry spills by scooping, shoveling or
vacuuming and place into containers for reuse or disposal. Wear respirator, protective clothing and
gloves. Keep unnecessary people away. Isolate hazard area and deny entry to avoid material dispersal.

SECTION 8: EXPOSURE CONTROLS, PERSONAL PROTECTION
EXPOSURE LIMITS: No occupational exposure limits established by OSHA/ACGIH/NIOSH.
VENTILATION: Provide local exhaust or process enclosure ventilation.
EYE PROTECTION: Wear safety glasses with splash shields or safety goggles/shield to prevent contact
with this product.
EMERGENCY WASH FACILITIES: Where there is any possibility that an employee鈥檚 eyes and/or skin
may be exposed to this product, the employer should provide an eye wash fountain and quick drench
shower within the immediate work area for emergency use.
CLOTHING: Wear appropriate protective clothing and equipment to prevent repeated or prolonged skin
contact with this product. Although skin contamination is not generally a problem, it increases the
possibility of ingestion through poor personnel hygiene. Contaminated work clothing and shoes should
not be taken from the workplace.
GLOVES: Wear appropriate protective gloves to prevent contact with this product.

TARGET EFFECTS: Poisoning may affect the liver and kidneys
HEALTH EFFECTS:
INHALATION (Zinc Sulfate):
Acute Exposure: Inhalation of dust may cause irritation or the respiratory tract with sore throat,
coughing, shortness or breath, labored breathing, pain in the nose, mouth, and throat, and burns
of the mucous membranes. If sufficient quantities are inhaled, pulmonary edema may develop,
often with a latent period of 5 - 72 hours. The symptoms may include tightness in the chest,
dyspnea, frothy sputum, cyanosis, and dizziness. Physical findings may include weak, rapid
pulse, hypotension, hemoconcentration, and moist rales.
Chronic Exposure: Depending on the concentration and duration of exposure, repeated or
prolonged exposure may cause inflammatory and ulcerative changes in the mouth and possibly
bronchial and gastrointestinal disturbances.
SKIN CONTACT (Zinc Sulfate):
Acute Exposure: Direct contact may cause severe irritation, redness, pain, and possibly burns.
Chronic Exposure: Effects depend on concentration and duration of exposure. Repeated or
prolonged contact with metal salts may result in dermatitis with erythematous, papular, and
granulomatous reactions in susceptible individuals or effects similar to acute exposure.
EYE CONTACT (Zinc Sulfate):
Acute Exposure: Direct contact may cause severe irritation, redness, pain, blurred vision, and burns,
possibly severe. The degree of injury depends on the concentration and duration of contact. The
full extent of the injury may not be immediately apparent. Application of a 20% zinc sulfate
solution to corneas infected with herpetic keratitis ulcers resulted in edema and residual scarring
upon healing.
Chronic Exposure: Effects depend on concentration and duration of exposure. Repeated or
prolonged contact may result in conjunctivitis or effects as in acute exposure.
INGESTION (Zinc Sulfate):
Acute Exposure: Ingestion may cause a burning pain in the mouth and throat, fever, nausea, violent
vomiting with severe abdominal pain , watery or bloody diarrhea, prostration, tenemus, retching,
hyperglycemia, anuria, liver damage, kidney damage with albuminuria, acetonuria, and
glycosuria, hypotension, sudden collapse, and convulsions.
Chronic Exposure: Depending on the concentration, repeated ingestion may cause effects as with
acute ingestion. Prolonged ingestion of 33,000 mg/kg in drinking water resulted in severe
anemia in mice. Reproductive effects have been reported in animals (anhydrous).
