Potential Health Effects
----------------------------------

Inhalation:
Extremely destructive to tissues of the mucous
membranes and upper respiratory tract. Symptoms may include burning sensation,
coughing, wheezing, laryngitis, shortness of breath, headache, nausea and
vomiting.
Ingestion:
Toxic. May cause irritation or corrosion
to the gastrointestinal tract with abdominal pain, nausea, and vomiting. May
cause delayed death occurring from strictures of the esophagus and pylorus.

Skin Contact:
May cause severe irritation, skin burns and
ulcerations. Solutions are corrosive. Symptoms include redness and pain.

Eye Contact:
May cause redness, pain, and blurred vision.
Splashes from solutions may cause eye damage.
Chronic Exposure:

Repeated skin contact can cause varying degrees of problems ranging from
dermatitis to ulcerations. Repeated Inhalation can cause occupational asthma.

Aggravation of Pre-existing Conditions:
Dermatitis, cardiac and
respiratory disorders.

4. First Aid Measures

Inhalation:
Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Get medical
attention immediately.
Ingestion:
If swallowed, DO NOT INDUCE
VOMITING. Give large quantities of water. Never give anything by mouth to an
unconscious person. Get medical attention immediately.
Skin
Contact:
Immediately flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Get medical attention
immediately. 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.

5. Fire Fighting Measures

Fire:
Not considered to be a fire hazard.

Explosion:
Not considered to be an explosion hazard.

Fire Extinguishing Media:
Use any means suitable for
extinguishing surrounding fire.
Special Information:
Use
protective clothing and breathing equipment appropriate for the surrounding
fire.

6. Accidental Release Measures

Ventilate area of leak or spill. Keep unnecessary and unprotected
people away from area of spill. Wear appropriate personal protective equipment
as specified in Section 8. Spills: Pick up and place in a suitable container
for reclamation or disposal, using a method that does not generate dust. Avoid
release to the environment. US Regulations (CERCLA) require reporting spills
and releases to soil, water and air in excess of reportable quantities. The
toll free number for the US Coast Guard National Response Center is (800)
424-8802.

7. Handling and Storage

Keep in a well closed container stored under cold to warm
conditions, 2 to 40 C, (36 to 104F). Protect against physical damage.
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.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
Zinc chloride:
OSHA
Permissible Exposure Limit (PEL):
1 mg/m3 (TWA) 8H, as fume.
ACGIH
Threshold Limit Value (TLV):
1 mg/m3 (TWA); 2 mg/m3 (STEL) for fume

Ventilation System:
A system of local and/or general exhaust is
recommended to keep employee exposures below the Airborne Exposure Limits.
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):
If the exposure
limit is exceeded, a full facepiece respirator with dust/mist filter may be
worn up to 50 times the exposure limit or the maximum use concentration
specified by the appropriate regulatory agency or respirator supplier,
whichever is lowest. For emergencies or instances where the exposure levels
are not known, use a full-facepiece 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 full face shield where dusting or splashing of
solutions is possible. Maintain eye wash fountain and quick-drench facilities
in work area.
