Section 3. Hazards Identification
Potential Acute Health Effects Very hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion. Hazardous in case of skin
contact (corrosive), of eye contact (corrosive), in case of inhalation. 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. Inflammation of the eye is characterized by redness, watering, and itching. Skin
inflammation is characterized by itching, scaling, reddening, or, occasionally, blistering.

CARCINOGENIC EFFECTS: Not available.
Potential Chronic Health
MUTAGENIC EFFECTS: Mutagenic for mammalian somatic cells. [Sodium hydroxide].
Effects
TERATOGENIC EFFECTS: Not available.
DEVELOPMENTAL TOXICITY: Not available.
The substance may be toxic to mucous membranes, 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.
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 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. Seek medical attention.
Ingestion Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an
unconscious person. If large quantities of this material are swallowed, call a physician immediately. Loosen tight
clothing such as a collar, tie, belt or waistband.
Serious Ingestion Not available.

Section 6. 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. Be careful that the product is not present at a concentration level above TLV.
Check TLV on the MSDS and with local authorities.
Section 7. Handling and Storage
Keep locked up.. Keep container dry. Do not breathe gas/fumes/ vapor/spray. Never add water to this product.
Precautions
In case of insufficient ventilation, wear suitable respiratory equipment. If you feel unwell, seek medical attention
and show the label when possible. Avoid contact with skin and eyes. Keep away from incompatibles such as
oxidizing agents, reducing agents, metals, acids, alkalis, moisture.
Keep container tightly closed. Keep container in a cool, well-ventilated area.
Storage
Section 8. Exposure Controls/Personal Protection
Engineering Controls Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their
respective threshold limit value.
Personal Protection Face shield. Full suit. Vapor respirator. Be sure to use an approved/certified respirator or equivalent. Gloves.
Boots.
Personal Protection in Case of Splash goggles. Full suit. Vapor respirator. Boots. Gloves. A self contained breathing apparatus should be
a Large Spill used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist
BEFORE handling this product.
