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 the dust or mist is apparent,
a half-face dust/mist respirator may be worn. 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.
9. Physical and Chemical Properties
Appearance: White or gray-white granules.
Odor: Odorless.
Solubility: Freely soluble in water,
exothermic.
Density: 2.15
pH: 8 - 9 Aqueous solution
% Volatiles by volume @ 21C (70F): 0
Boiling Point: > 1600C (> 2912F)
Melting Point: 772C (1422F)
Vapor Density (Air=1): No
information found.

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.
