contact (permeator), of inhalation. Slightly hazardous in case of skin contact (corrosive). 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.
MUTAGENIC EFFECTS: Not available.
TERATOGENIC EFFECTS: Not available.
DEVELOPMENTAL TOXICITY: Not available.
The substance is toxic to lungs, mucous membranes.
Repeated or prolonged exposure to the substance can produce target organs damage.

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. Do not use an eye ointment. Seek medical attention.
Skin Contact:
After contact with skin, wash immediately with plenty of water. Gently and thoroughly wash the contaminated skin
with running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin.
Cover the irritated skin with an emollient. 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 immediate
medical attention.
Inhalation: Allow the victim to rest in a well ventilated area. Seek immediate medical attention.
Serious Inhalation: Not available.
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 immediate medical attention.
Serious Ingestion: Not available.

Section 7: Handling and Storage
Precautions:
Keep container dry. Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire
risk, evaporate the residue under a fume hood. Ground all equipment containing material. Do not ingest. Do not
breathe dust. 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
Storage:
Keep container dry. Keep in a cool place. Ground all equipment containing material. Keep container tightly
closed. Keep in a cool, well-ventilated place. Combustible materials should be stored away from extreme heat
and away from strong oxidizing agents.
Section 8: 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. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.
Gloves.
Personal Protection in Case of a Large Spill:
Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used
