HAZARDS IDENTIFICATION
_________________________________________________________________
POTENTIAL ACUTE HEALTH EFFECTS:
Slightly dangerous to dangerous in case of ingestion, of
inhalation. Very slightly to slightly dangerous in case of
skin contact (irritant, permeator), of eye contact
(irritant). Corrosive to eyes and skin. 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 over-exposure can produce lung damage, choking,
unconsciousness or death. This product may irritate eyes
and skin upon contact.
POTENTIAL CHRONIC HEALTH EFFECTS:
CARCINOGENIC EFFECTS: Not available.
MUTAGENIC EFFECTS: Not available.
TERATOGENIC EFFECTS: Not available.
The substance is toxic to mucous membranes. Toxicity of the
product to the reproductive system: Not available. Repeated
or prolonged exposure to the substance can produce target
organs damage. 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.

FIRST AID MEASURES
_________________________________________________________________
EYE CONTACT:
Check for and remove any contact lenses. IMMEDIATELY flush
eyes with running water for at least 15 minutes, keeping
eyelids open. COLD water may be used. DO NOT use an eye
ointment. Seek medical attention.
SKIN CONTACT:
If the chemical got onto the clothed portion of the body,
remove the contaminated clothes as quickly as possible,
protecting your own hands and body. Place the victim under
2
a deluge shower. If the chemical touches the victim's
exposed skin such as the hands: Neutralize exposed skin
with a dilute solution of sodium carbonate. Gently and
thoroughly wash the contaminated skin with running water and
non-abrasive soap. Be particularly careful to clean folds,
crevices, creases and groin. COLD water may be used. If
irritation persists, seek medical attention. Wash
contaminated clothing before reusing.
SERIOUS SKIN CONTACT:
Wash with a disinfectant soap and cover the contaminated
skin with an anti-bacterial cream. Seek medical attention.
INHALATION:
Allow the victim to rest in a well ventilated area. Seek
immediate 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 dangerous 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. Have conscious person drink several
glasses of water or milk. Seek immediate medical attention.
SERIOUS INGESTION:
DO NOT induce vomiting. Examine the lips and mouth to
ascertain whether the tissues are damaged, a possible
indication that the toxic material was ingested; the absence
of such signs, however, is not conclusive. Loosen tight
clothing such as a collar, tie, belt, or waistband. If the
victim is not breathing, perform mouth-to-mouth
resuscitation. Seek medical attention.

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 sodium
carbonate.
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. Eliminate all sources of
ignition. Call for assistance on disposal. Neutralize the
residue with a dilute solution of sodium carbonate.

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 a MSHA/NIOSH approved respirator
or equivalent. Gloves. Wear appropriate respirator when
ventilation is inadequate.
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.
