Section
3: Hazards Identification Potential Acute Health Effects:
Very
hazardous in case of skin contact (irritant), of eye contact (irritant), of
ingestion, of inhalation. Hazardous in case of skin contact (corrosive,
permeator), of eye contact (corrosive). The amount of tissue damage depends on
length of contact. Eye contact can result in corneal damage or blindness. Skin
contact can produce inflammation and blistering. Inhalation of dust will produce
irritation to gastro-intestinal or respiratory tract, characterized by burning,
sneezing and coughing. Severe overexposure can produce lung damage, choking,
unconsciousness or death. Inflammation of the eye is characterized by redness,
watering, and itching. Skin inflammation is characterized by itching, scaling,
reddening, or, occasionally, blistering.
Potential
Chronic Health Effects:
CARCINOGENIC
EFFECTS: Not available. MUTAGENIC EFFECTS: Not available. TERATOGENIC EFFECTS:
Not available.
DEVELOPMENTAL
TOXICITY: Not available. Repeated exposure of the eyes to a low level of dust
can produce eye irritation. Repeated skin exposure can produce local skin
destruction, or dermatitis. Repeated inhalation of dust can produce varying
degree of respiratory irritation or lung damage.
Section
4: First Aid Measure 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. WARM water
MUST be used. Get medical attention immediately.
Skin
Contact:In case of
contact, immediately flush skin with plenty of water for at least 15 minutes
while removing contaminated clothing and shoes. Cover the irritated skin with an
emollient. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get
medical attention immediately.
Serious
Skin Contact: Wash with a
disinfectant soap and cover the contaminated skin with an anti-bacterial cream.
Seek medical attention.
Inhalation:
If inhaled, remove to
fresh air. If not breathing, give artificial respiration. If breathing is
difficult, give oxygen. Get medical attention.
Serious
Inhalation:Evacuate the
victim to a safe area as soon as possible. Loosen tight clothing such as a
collar, tie, belt or waistband. If breathing is difficult, administer oxygen. If
the victim is not breathing, perform mouth-to-mouth resuscitation. WARNING: It
may be hazardous to the person providing aid to give mouth-to-mouth
resuscitation when the inhaled material is toxic, infectious or corrosive. Seek
immediate 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.
Serious
Ingestion: Not available.

Section
6: Accidental Release Measures Small Spill:
Use
appropriate tools to put the spilled solid in a convenient waste disposal
container. If necessary: Neutralize the residue with a dilute solution of acetic
acid.
Large
Spill: Corrosive solid.
Stop leak if without risk. Do not get water inside container. Do not touch
spilled material. Use water spray to reduce vapors. Prevent entry into sewers,
basements or confined areas; dike if needed. Call for assistance on disposal.
Neutralize
the residue with a dilute solution of acetic acid. Be careful that the product
is not present at a concentration level above TLV. Check TLV on the MSDS and
with local authorities.
Section
7: Handling and Storage Precautions: Keep
container dry. Do not breathe dust. Never add water to this product. In case of
insufficient ventilation, wear suitable respiratory equipment. If you feel
unwell, seek medical attention and show the label when possible. Avoid contact
with skin
and
eyes. Keep away from incompatibles such as organic materials, acids, moisture.
Storage:
Keep container tightly
closed. Keep container in a cool, well-ventilated area. Do not store above 24°C
(75.2°F).
Section
8: Exposure Controls/Personal Protection Engineering Controls:
Use
process enclosures, local exhaust ventilation, or other engineering controls to
keep airborne levels below recommended exposure limits. If user operations
generate dust, fume or mist, use ventilation to keep exposure to airborne
contaminants below the exposure limit.
Personal
Protection:Splash goggles.
Synthetic apron. Vapor and dust respirator. Be sure to use an approved/certified
respirator or equivalent. Gloves.
Personal
Protection in Case of a Large Spill:Splash
goggles. Full suit. Vapor and dust respirator. Boots. Gloves. A self contained
breathing apparatus should be used to avoid inhalation of the product. Suggested
protective clothing might not be sufficient; consult a specialist BEFORE
handling this product.
Exposure
Limits:TWA: 2 (mg/m3) from
ACGIH (TLV) [United States] TWA: 2 (mg/m3) [Canada] TWA: 5 (mg/m3) from OSHA

Conditions
of Instability: Incompatible
materials
Incompatibility
with various substances: Reactive
with organic materials, acids, moisture.
Corrosivity:
Not available.
Special
Remarks on Reactivity:
Absorbs
CO2 from air. Reacts with fluorine to evolve much heat and some light. Reacts
with water. Addition of water to Quicklime has generated temperatures as high as
800 C. Some reports describe the reaction as violent. In water, calcium oxide
forms calcium hydroxide generating a large quanity of heat. Ignition of sulfur,
gunpowder, wood, and straw by heat of Quicklime-water reaction has been
reported. Liquid hydrofluoric acid and calcium oxide react very violently.
Calcium reacts
with
phosphorous pentoxide extremely violently when initiated by local heating. Lime
becomes incandescent when heated to near its melting point (2500 C).
