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

Inhalation:
Granular material does not pose a significant
inhalation hazard, but inhalation of dust may cause irritation to the
respiratory tract, with symptoms of coughing and shortness of breath.

Ingestion:
Low toxicity material but ingestion may cause
serious irritation of the mucous membrane due to heat of hydrolysis. Large
amounts can cause gastrointestinal upset, vomiting, abdominal pain.

Skin Contact:
Solid may cause mild irritation on dry skin;
strong solutions or solid in contact with moist skin may cause severe
irritation, even burns.
Eye Contact:
Hazard may be either
mechanical abrasion or, more serious, burns from heat of hydrolysis and
chloride irritation.
Chronic Exposure:
No information found.

Aggravation of Pre-existing Conditions:
No information found.

4. First Aid Measures

Inhalation:
Remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion:
Induce vomiting immediately as directed
by medical personnel. 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.

Note to Physician:
Oral ingestion may cause
serum acidosis.

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:
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. At high temperatures or when
moistened under fire conditions, calcium chloride may produce toxic or
irritating fumes.

6. Accidental Release Measures

Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Spills: Sweep up and
containerize for reclamation or disposal. Vacuuming or wet sweeping may be
used to avoid dust dispersal. Small amounts of residue may be flushed to sewer
with plenty of water.

7. Handling and Storage

Keep in a tightly closed container, stored in a cool, dry,
ventilated area. Protect against physical damage. Moist calcium chloride and
concentrated solutions can corrode steel. When exposed to the atmosphere,
calcium chloride will absorb water and form a 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.

8. Exposure Controls/Personal Protection

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
protective gloves and clean body-covering clothing.
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.
Other Control Measures:

Maintain good housekeeping in work area. Dust deposits on floors and other
surfaces may pick up moisture and cause the surfaces to become slippery and
present safety hazards.

10. Stability and Reactivity

Stability:
Stable under ordinary conditions of use and
storage. Substance will pick up moisture from the air and go into solution if
exposed in open containers.
Hazardous Decomposition Products:

Emits toxic chlorine fumes when heated to decomposition. May form hydrogen
chloride in presence of sulfuric or phosphoric acids or with water at elevated
temperatures.
Hazardous Polymerization:
Will not occur.

Incompatibilities:
Methyl vinyl ether, water, zinc, bromine
trifluoride, mixtures of lime and boric acid, barium chloride, and 2-furan
percarboxylic acid. Metals will slowly corrode in aqueous calcium chloride
solutions. Aluminum (and alloys) and yellow brass will be attacked by calcium
chloride.
Conditions to Avoid:
Incompatibles.

13. Disposal Considerations

Whatever cannot be saved for recovery or recycling should be
managed in an appropriate and approved waste disposal facility. Processing,
use or contamination of this product may change the waste management options.
State and local disposal regulations may differ from federal disposal
regulations. Dispose of container and unused contents in accordance with
federal, state and local requirements.
