HAZARDS IDENTIFICATION
_________________________________________________________________
POTENTIAL ACUTE HEALTH EFFECTS:
Very dangerous in case of skin contact (corrosive,
irritant), of eye contact (irritant), of ingestion.
Slightly dangerous to dangerous in case of inhalation. Not
dangerous in case of skin contact (non-sensitizer for
skin). Corrosive to eyes and skin. Corrosive to skin and
eyes on contact. 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. This product may irritate eyes
and skin upon contact. 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:
Not dangerous in case of skin contact (non-corrosive for
skin, non-irritant for skin, non-permeator by skin), of eye
contact (non-irritant), of ingestion, of inhalation.
CARCINOGENIC EFFECTS: Not available.
MUTAGENIC EFFECTS: Not available.
TERATOGENIC EFFECTS: Not available.
2
The substance is toxic to lungs, 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 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.

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. Rinse with a dilute solution of boric acid.
Finish by rinsing thoroughly with running water to avoid a
possible infection. COLD water may be used.
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
a deluge shower. If the chemical touches the victim's
exposed skin such as the hands. Neutralize exposed skin with
a dilute solution of boric acid or acetic acid. 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.
3
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 an 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:
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 acetic acid.
LARGE SPILL:
Corrosive liquid.
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 acetic acid.
