RE: Deice trucks/MSDS
Hi David,
I have to agree with you regarding avoiding the use of CaCl2 on the roads.
While it is less hazardous than salt in a lot of ways, the calcium chloride
dust is less than desirable. Once the snow and ice is gone, the calcium
chloride remains. I'd rather drive a bit more carefully on untreated roads.
Regarding the "slippery" nature of calcium chloride. If there is
insufficient water to dissolve it, it becomes like a "mud" and is indeed
slippery. This is what the MSDS refers to. However, when applied to snow or
ice, I believe it is already dissolved in water (as a de-icer, it only works
when dissolved) and is not at all slippery.
I do agree that it makes snowy roads more slick as it turns snow into slush.
Personally, I have a lot more trouble driving in deep slush.
Thanks
Bill Strand

Heck if this is the stuff that is being sprayed on the roads I wish they
would stop.
Notice that at the end of #8 it makes surfaces....slippery?!
So its not your imagination if you think so too.

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.

hydrogen
chloride in presence of sulfuric or phosphoric acids or with water at
elevated
