Section 3: Hazards Identification
Potential Acute Health Effects:
Hazardous in case of eye contact (irritant), of inhalation (lung irritant). Slightly hazardous in case of skin contact (irritant,
sensitizer), of ingestion. The amount of tissue damage depends on length of contact. Eye contact can result in corneal
damage or blindness. Skin contact can produce inflammation and blistering. Severe over-exposure can produce lung damage,
choking, unconsciousness or death.
Potential Chronic Health Effects:
Slightly hazardous in case of skin contact (sensitizer). CARCINOGENIC EFFECTS: Not available. MUTAGENIC EFFECTS:
Not available. TERATOGENIC EFFECTS: Not available. DEVELOPMENTAL TOXICITY: Not available. The substance may
be toxic to teeth. Repeated or prolonged exposure to the substance can produce target organs damage. Repeated exposure
of the eyes to a low level of dust can produce eye irritation. Repeated skin exposure can produce local skin destruction, or
dermatitis. Repeated inhalation of dust can produce varying degree of respiratory irritation or lung damage.

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.
Skin Contact:
In case of contact, immediately flush skin with plenty of water. Cover the irritated skin with an emollient. Remove contaminated
clothing and shoes. Cold water may be used.Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical
Serious Skin Contact:
Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical attention.
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical
Serious Inhalation: Not available.
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.

Special Remarks on Explosion Hazards: Not available.
Section 6: Accidental Release Measures
Small Spill:
Use appropriate tools to put the spilled solid in a convenient waste disposal container. If necessary: Neutralize the residue
with a dilute solution of sodium carbonate. Finish cleaning by spreading water on the contaminated surface and dispose of
according to local and regional authority requirements.
p. 2
Large Spill:
Stop leak if without risk. Do not get water inside container. Do not touch spilled material. Use water spray to reduce vapors.
Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all ignition sources. Call for assistance
on disposal. Neutralize the residue with a dilute solution of sodium carbonate. Finish cleaning by spreading water on the
contaminated surface and allow to evacuate through the sanitary system.
Section 7: Handling and Storage
Keep away from heat. Keep away from sources of ignition. Ground all equipment containing material. Do not ingest. Do not
breathe dust. Wear suitable protective clothing 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 oxidizing agents, reducing agents, alkalis.
Storage: Keep container tightly closed. Keep container in a cool, well-ventilated area.
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:
Safety glasses. Lab coat. Gloves (impervious). Dust respirator. Be sure to use an approved/certified respirator or equivalent.
The dust respirator should be used for conditions where exposure has exceeded recommended exposure limits, dust is
apparent, and engineering controls(adequate ventilation) are not feasible.
Personal Protection in Case of a Large Spill:
Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid
inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this
