Section 3: Hazards Identification
Potential Acute Health Effects:
Very hazardous in case of skin contact (corrosive, irritant, permeator), of eye contact (irritant, corrosive), of ingestion. 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 mayproduce severe irritation of respiratory tract, characterized by
coughing, choking, or shortness of breath. Severe over-exposure can result in 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:
Non-corrosive for skin. Non-irritant forskin. Non-sensitizer for skin. Non-permeator by skin. Non-irritating to the eyes.
Non-hazardous in case of ingestion. Non-hazardous in case of inhalation. Non-irritant for lungs. Non-sensitizer for lungs.
CARCINOGENIC EFFECTS: Not available. MUTAGENIC EFFECTS: Not available. TERATOGENIC EFFECTS: Not available.
DEVELOPMENTAL TOXICITY: Not available. The substance may be toxic to lungs, mucousmembranes, skin, eyes, bones,

teeth. 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. Repeated exposure to ahighly toxic
material may produce general deterioration of health by an accumulation in one or many human organs.

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 15-30
minutes. Cold water may be used. Keep the eyelids apart and away from the eyeballs during irrigation. Do not useoily drops
or ointment or HF skin burn treatments on the eyes. Get medical attention immediately, preferrably an eye specialist. If a
physician is not immediately available, apply one or two drops of ophthalmic anesthetic (e.g. 0.5% Pontocaine Hydrochloride
solution). Place ice pack on eyes until reaching emergency room.
Skin Contact:
In case of contact, immediately flush skin with plenty ofwater 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. While waiting for medical attention, it has been shown that flushing
the affected area with water for one minute and then massaging HF Antidote Gel...
