4. FIRST AID MEASURES
Ingestion
DO NOT induce vomiting. Have conscious person drink several glasses of water or milk. Seek immediate medical attention.SERIOUS 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 medical attention.
Inhalation
Allow the victim to rest in a well ventilated area. Seek immediate medical attention.
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 dangerous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled material is toxic, infectious or corrosive. Seek immediate medical attention.
Skin Contact
If the chemical got onto the clothed portion of the body, remove the contaminated clothes as quickly as possible, protecting your own hands and body. Place the victim under a deluge shower. If the chemical touches the victim's exposed skin such as the hands. Neutralize exposed skin with a dilute solution of boric acid or acetic acid. Gently and thoroughly wash the contaminated skin with running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. COLD water may be used. 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 medical attention.
Eye Contact
Check for and remove any contact lenses. IMMEDIATELY flush eyes with running water for at least 15 minutes, keeping eyelids open. Rinse with a dilute solution of boric acid. Finish by rinsing thoroughly with running water to avoid a possible infection. COLD water may be used.
Other Information
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, characterised by coughing, choking, or shortness of breath. This product may irritate eyes and skin upon contact. Inflammation of the eye is characterised by redness, watering, and itching. Skin inflammation is characterised by itching, scaling, reddening, or, occasionally, blistering.
5. FIREFIGHTING MEASURES
Suitable extinguishing equipment

Special protective equipment and precautions for fire fighters
No special measures required.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures
Ensure adequate ventilation, remove unnecessary personnel from area. Wear appropriate protective clothing
Environmental precautions
Do not let enter drains unless heavily diluted.
Methods and materials for containment and clean up
SMALL SPILL:
Dilute with water and mop up, or absorb with an inert DRY liquid-binding material (sand, diatomite, acid binders, universal binders, sawdust). Use neutralizing agent. Reduce the risk of producing vapours/mist 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 vapour 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.
7. HANDLING AND STORAGE
Precautions for safe handling
Keep container dry. DO NOT ingest. Do not breathe gas, fumes, vapour or spray. 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. Keep away from incompatibles as moisture.
Conditions for safe storage
Alkalis may be stored in heavy duty gauge steel containers. Corrosive materials should be stored in a separate safety storage cabinet or room. Keep container tightly sealed. Store in a cool, dry location. Keep away from foodstuffs, beverages and feed.

Engineering controls
Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapours below their respective threshold limit value. Ensure that eyewash station and safety shower is proximal to the work-station location.
Personal protective equipment
Eye and face protection
Tightly sealed goggles
Skin protection
Protective gloves. The glove material has to be impermeable and resistant to the product/ the substance/ the preparation. Due to missing tests no recommendation to the glove material can be given for the product/ the preparation/ the chemical mixture. Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation.Material of gloves:The selection of the suitable gloves does not only depend on the material, but also on further marks of quality and varies from manufacturer to manufacturer. As the product is a preparation of several substances, the resistance of the glove material cannot be calculated in advance and has therefore to be checked prior to the application.Penetration time of glove material:The exact break through time has to be found out by the manufacturer of the protective gloves and has to be observed.
Body protection
Wear suitable clothing to prevent contact with skin. Full suit and boots.
Respiratory protection
In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use self-contained respiratory protective device.Wear appropriate respirator when ventilation is inadequate. Be sure to use a MSHA/NIOSH approved respirator or equivalent.
