Potential Acute Health Effects:
Very hazardous in case of skin contact (corrosive, irritant, permeator), of eye contact (irritant), of ingestion, .
Non-corrosive to the eyes. Non-corrosive for lungs. 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. 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:
CARCINOGENIC EFFECTS: Not available.



p. 1
MUTAGENIC EFFECTS: Mutagenic for bacteria and/or yeast. [Ammonia, anhydrous].
TERATOGENIC EFFECTS: Not available.
DEVELOPMENTAL TOXICITY: Not available.
The substance is toxic to upper respiratory tract, skin, eyes.
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 a highly 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. Immediately flush eyes with running water for at least 15 minutes,
keeping eyelids open. Cold water may be used. Get medical attention immediately. Finish by rinsing thoroughly
with running water to avoid a possible infection.

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 medical attention.
