Section
3: Hazards Identification Potential Acute Health Effects:
Very
hazardous in case of ingestion, . Hazardous in case of skin contact (corrosive,
permeator). Slightly hazardous in case of eye contact (irritant), of inhalation
(lung sensitizer). Liquid or spray mist may produce tissue damage particularly
on mucous membranes of eyes, mouth and respiratory tract. Skin contact may
produce burns. Inhalation of the spray mist may produce severe irritation of
respiratory tract, characterized by coughing, choking, or shortness of breath.
Potential
Chronic Health Effects: Slightly
hazardous in case of skin contact (irritant), of eye contact (irritant), of
ingestion, of inhalation. Non-sensitizer for skin. CARCINOGENIC EFFECTS: Not
available. MUTAGENIC EFFECTS: Not available. TERATOGENIC EFFECTS: Not available.
DEVELOPMENTAL TOXICITY: Not available. The substance is toxic to blood, kidneys,
lungs, mucous membranes, bladder, gastrointestinal tract, upper respiratory
tract. Repeated or prolonged exposure to the substance can produce target organs
damage. Repeated or prolonged contact with spray mist may produce chronic eye
irritation and severe skin irritation. Repeated or prolonged exposure to spray
mist may produce respiratory tract irritation leading to frequent attacks of
bronchial infection.
Section
4: First Aid Measures 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 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. Cold water may be used. 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 immediate medical attention.
Inhalation:
If inhaled, remove to
fresh air. If not breathing, give artificial respiration. If breathing is
difficult, give oxygen. Get medical attention immediately.
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. Loosen tight clothing such as a collar, tie, belt or
waistband. Get medical attention if symptoms appear.
Serious
Ingestion: Not available.

Dilute
with water and mop up, or absorb with an inert dry material and place in an
appropriate waste disposal container. If necessary: Neutralize the residue with
a dilute solution of sodium carbonate.
Large
Spill: Flammable liquid.
Corrosive liquid. Keep away from heat. Keep away from sources of ignition. Stop
leak if without risk. Absorb with DRY earth, sand or other non-combustible
material. Do not get water inside container. Do not touch spilled material. Use
water spray curtain to divert vapor drift. Prevent entry into sewers, basements
or confined areas; dike if needed. Call for assistance on disposal. Neutralize
the residue with a dilute solution of sodium carbonate. 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. Keep away from heat. Keep away from sources of ignition. Ground
all equipment containing material. Do not ingest. Do not breathe gas/fumes/
vapor/spray. Never add water to this product. In case of insufficient
ventilation, wear suitable respiratory equipment. If ingested, seek medical
advice immediately and show the container or the label. Avoid contact with skin
and eyes. Keep away from incompatibles such as acids, alkalis. May corrode
metallic surfaces. Store in a metallic or coated fiberboard drum using a strong
polyethylene inner package.
Storage:
Store in a segregated and
approved area. Keep container in a cool, well-ventilated area. Keep container
tightly closed and sealed until ready for use. Avoid all possible sources of
ignition (spark or flame).
Section
