Ingredient CAS No Percent Hazardous
----------------- ------------ ------------ ---------
Zinc Sulfate 7733-02-0 100% Yes
Inhalation: Causes irritation to the respiratory tract. Symptoms may
include coughing, shortness of breath.
Ingestion: As with other soluble zinc salts, zinc sulfate may hydrolyze
into acid if swallowed. Severe irritation and burns of the mouth, throat and
digestive system may occur. Symptoms may include vomiting, stomach pain,
increased pulse rate without blood pressure decrease, blood pressure decrease,
acute pulmonay edema (fluid in the lungs), diarrhea, kidney damage, other
gastrointestinal disturbances and hemorrhagic pancreatitis. A fatality following
ingestion of 10 grams has been reported.
Skin Contact: Causes irritation to skin. Symptoms include redness,
itching, and pain.
Eye Contact: Irritant, can cause pain and redness, possible mechanical
harm. May cause severe irritation.
Chronic Exposure: Chronic exposure may cause fatigue, slow tendon
reflexes, intestinal inflammation (with bleeding), diarrhea, blood effects,
central nervous system depression, tremors and paralysis of the extremities.
Repeated skin or eye contact can cause skin and eye effects.
Aggravation of Pre-existing Conditions: Persons with pre-existing skin
disorders or impaired respiratory function may be more susceptible to the
effects of the substance.
Inhalation: Remove to fresh air. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion: If swallowed, give several glasses of water to drink. Vomiting
may occur spontaneously, but DO NOT INDUCE! Never give anything by mouth to an
unconscious person. Get medical attention.
Skin Contact: Wipe off excess material from skin then immediately flush
skin with plenty of water for at least 15 minutes. Remove contaminated clothing
and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean
shoes before reuse.
Eye Contact: Immediately flush eyes with plenty of water for at least 15
minutes, lifting lower and upper eyelids occasionally. Get medical attention
immediately.
Fire: Not considered to be a fire hazard.
Explosion: Sealed containers may rupture when heated.
Fire Extinguishing Media: Use any means suitable for extinguishing
surrounding fire. Use water carefully as material will react with water to form
acidic solution. Water spray may be used to keep fire exposed containers cool.
Special Information: In the event of a fire, wear full protective
clothing and NIOSH-approved self-contained breathing apparatus with full
facepiece operated in the pressure demand or other positive pressure mode. Zinc
sulfate can decompose at high temperatures to form toxic oxides, sulfur and zinc
oxide as well as water vapor. Sealed containers of this material may rupture at
moderate temperatures (release of water vapor). Forms acidic solutions in water.
Ventilate area of leak or spill. Keep unnecessary and unprotected people away from area of spill.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Material dissolves in water to form an acidic solution. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Airborne Exposure Limits: None established.
Ventilation System: A system of local and/or general exhaust is
recommended to keep employee exposures as low as possible. Local exhaust
ventilation is generally preferred because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general work
area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of
Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): For
conditions of use where exposure to dust or mist is apparent and engineering
controls are not feasible, a particulate respirator (NIOSH type N95 or better
filters) may be worn. If oil particles (e.g. lubricants, cutting fluids,
glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or
instances where the exposure levels are not known, use a full-face
positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators
do not protect workers in oxygen-deficient atmospheres.
Skin Protection: Wear impervious protective clothing, including boots,
gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection: Use chemical safety goggles and/or a full face shield
where splashing is possible. Maintain eye wash fountain and quick-drench
facilities in work area.
