Section 3. Hazards Identification
Potential Acute Health Effects Very hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation. Hazardous in
case of skin contact (corrosive), of eye contact (corrosive). 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.

Effects
TERATOGENIC EFFECTS: Not available.
DEVELOPMENTAL TOXICITY: Not available.
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. In case of contact, immediately flush eyes with plenty of water for at
least 15 minutes. Cold water may be used. Get medical attention immediately.
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. 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 immediate medical attention.
Ingestion If swallowed, 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 immediately.
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.
Large Spill Flammable liquid. Corrosive liquid. Poisonous liquid.
Keep away from heat. Keep away from sources of ignition. 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. Use water spray to reduce vapors. Prevent entry into sewers,
basements or confined areas; dike if needed. Call for assistance on disposal.

equipment. 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 metals, moisture.
Keep container tightly closed. Keep container in a cool, well-ventilated area. Keep from any possible contact with
Storage
water. Do not allow water to get into container because of violent reaction.
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. Ensure that eyewash stations and safety showers are proximal to the
work-station location.
Personal Protection Face shield. Full suit. Vapor respirator. Be sure to use an approved/certified respirator or equivalent. Gloves.
