Potential Health Effects
----------------------------------
Inhalation: Calcium Chloride 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. If inhaled, remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion: Do NOT induce vomiting
unless directed to do so by medical personnel. Never give anything by mouth
to an unconscious person. If large quantities of this material are
swallowed, call a physician immediately. Loosen tight clothing such as a
collar, tie, belt or waistband.
Skin Contact: Calcium Chloride 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: Check for and remove any contact
lenses. In case of contact, immediately flush eyes with plenty of water for
at
least 15 minutes. Cold water may be used. Get medical attention.
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: It is not considered to be a fire hazard.
Explosion: It is 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 face piece operated in the pressure
demand or other positive pressure mode. At high temperatures or when moistened
under fire conditions, it may produce toxic or irritating fumes.
6. Accidental Release Measures
Small Spill: Use
appropriate tools to put the spilled solid in a convenient waste
disposal container. Finish cleaning by
spreading water on the contaminated surface and dispose of according
to local and regional authority requirements.
Large Spill: Use a shovel to put the material into a
convenient waste disposal container. Finish cleaning by spreading
water on the contaminated surface and allow to evacuate through the
sanitary system.
7. Handling and Storage
Keep
Calcium Chloride 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.
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,
glycerin, 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.
9. Physical and Chemical Properties
Appearance:
It is white or gray-white granules.

Solubility:
It is freely soluble in water, exothermic.
Density:
Calcium Chloride has specific gravity of
2.15
pH:
8 - 9 Aqueous solution of Calcium Chloride
% Volatiles by volume @ 21C (70F):
0
Boiling Point:
> 1600C (> 2912F)
Melting Point: 772C (1422F)
Vapor Density (Air=1):
No information found.
Vapor Pressure (mm Hg):
No information found.
Evaporation Rate (BuAc=1):

10. Stability and Reactivity
Stability:
Calcium Chloride is 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: It emits toxic chlorine fumes when heated to decomposition. Calcium
Chloride 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.
11. Toxicological Information
Oral rat LD50: 1000 mg/kg. Investigated as a tumorigen and mutagen.
12. Ecological Information
Environmental Fate:
Based on available information for Calcium Chloride anhydrous, this material
will not biodegrade or bio accumulate.
Environmental Toxicity:
The LC50/96-hour values for fish are over 100 mg/l.
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
of Calcium Chloride and unused contents in accordance with federal, state and local requirements.
14. Transport Information
